 # osslsigncode change log
 
+### 2.14 (unreleased)
+
+- attach-signature now uses digest-only verification instead of full signature
+  validation; output file is not kept if digest verification fails
+
+### 2.13 (2026.02.10)
+
+**MULTIPLE SECURITY VULNERABILITIES**
+
+This release includes important security fixes. Users are strongly encouraged
+to upgrade, as the issues below may be exploitable when processing untrusted
+files.
+
+- fixed integer overflows when processing APPX compressed data streams
+  (by Małgorzata Olszówka)
+- fixed double-free vulnerabilities in APPX file processing
+  (by Małgorzata Olszówka)
+- fixed multiple memory corruption issues in PE page hash computation
+  (by Antoni Klajn (Opera) and Małgorzata Olszówka)
+
+### 2.12 (2026.02.02)
+
+**CRITICAL SECURITY VULNERABILITY**
+
+This release fixes a critical memory corruption vulnerability.  A malicious
+attacker could create a signed file, which, when verified with osslsigncode,
+triggers arbitrary code execution.  Any previous version of osslsigncode should
+be immediately upgraded if the tool is used for verification of untrusted
+files.
+
+- fixed a buffer overflow while extracting message digests
+  (reported and fixed by Antoni Klajn, Opera)
+
+### 2.11 (2026.01.20)
+- added keyUsage validation for signer certificate
+  (thanks to Hanqing Zhao and Zi-Quan You for reporting the issue)
+- added printing CRL details during signature verification
+- implemented a workaround for CRL servers returning the HTTP Content-Type
+  header other than application/pkix-crl (thanks to Chris Thibodeaux)
+- fixed HTTP keep-alive handling
+- fixed macOS compiler and linker flags
+- fixed undefined BIO_get_fp() behavior with BIO_FLAGS_UPLINK_INTERNAL
+
+### 2.10 (2025.06.23)
+
+- added JavaScript signing
+- added PKCS#11 provider support (requires OpenSSL 3.0+)
+- added support for providers without specifying "-pkcs11module" option
+  (OpenSSL 3.0+, e.g., for the upcoming CNG provider)
+- added compatibility with the CNG engine version 1.1 or later
+- added the "-engineCtrl" option to control hardware and CNG engines
+- added the '-blobFile' option to specify a file containing the blob content
+- improved unauthenticated blob support (thanks to Asger Hautop Drewsen)
+- improved UTF-8 handling for certificate subjects and issuers
+- fixed support for multiple signerInfo contentType OIDs (CTL and Authenticode)
+- fixed tests for python-cryptography >= 43.0.0
+
+### 2.9 (2024.06.29)
+
+- added a 64 bit long pseudo-random NONCE in the TSA request
+- missing NID_pkcs9_signingTime is no longer an error
+- added support for PEM-encoded CRLs
+- fixed the APPX central directory sorting order
+- added a special "-" file name to read the passphrase from stdin
+  (by Steve McIntyre)
+- used native HTTP client with OpenSSL 3.x, removing libcurl dependency
+- added '-login' option to force a login to PKCS11 engines
+  (by Brad Hughes)
+- added the "-ignore-crl" option to disable fetching and verifying
+  CRL Distribution Points
+- changed error output to stderr instead of stdout
+- various testing framework improvements
+- various memory corruption fixes
+
 ### 2.8 (2024.03.03)

+### Using the PKCS#11 Engine with osslsigncode
-An example of using osslsigncode with SoftHSM:
+If you want to use a PKCS#11 token, specify the PKCS#11 engine and module.
+Example usage with SoftHSM:
 ```
   osslsigncode sign \
-    -pkcs11engine /usr/lib64/engines-1.1/pkcs11.so \
+    -engine /usr/lib64/engines-1.1/pkcs11.so \

+### Using the PKCS#11 Provider with osslsigncode (OpenSSL 3.x only)
+OpenSSL 3.0 introduced a new provider-based architecture. To use a PKCS#11 token
+ with `osslsigncode`, specify the PKCS#11 provider and module.
+Example usage with OpenSC:
+```
+  osslsigncode sign \
+    -provider /usr/lib64/ossl-modules/pkcs11prov.so \
+    -pkcs11module /usr/lib64/opensc-pkcs11.so \
+    -pkcs11cert 'pkcs11:token=my-token;object=cert' \
+    -key 'pkcs11:token=my-token;object=key' \
+    -in yourapp.exe -out yourapp-signed.exe
+```
+
+### Using the CNG Engine with osslsigncode (Windows only)
+The CNG engine allows using certificates and keys stored in the Windows
+Certificate Store. It requires CNG engine version 1.1 or later. For more
+information, refer to
+
+  https://www.stunnel.org/cng-engine.html
+
+A non-commercial edition of CNG engine is available for testing, personal,
+educational, or research purposes.
+
+To ensure `osslsigncode` can locate and load the CNG engine module (`cng.dll`)
+even when it is not installed in the default system engine directory, you can:
+
+- Specify the full or relative path to `cng.dll`:
+```
+  osslsigncode sign -engine C:\my\engines\cng.dll ...
+```
+- Or set the `OPENSSL_ENGINES` environment variable to the directory containing
+`cng.dll`, and refer to the engine by its ID:
+```
+  set OPENSSL_ENGINES=C:\my\engines
+  osslsigncode sign -engine cng ...
+```
+
+Below is an example of how to use `osslsigncode` with the CNG engine on Windows:
+```
+  set OPENSSL_ENGINES=C:\my\engines
+  osslsigncode sign ^
+    -engine cng ^
+    -pkcs11cert osslsigncode_cert ^
+    -key osslsigncode_cert ^

+# DESCRIPTION
+
+`osslsigncode` signs and verifies Microsoft Authenticode signatures on
+supported file formats.  It can also extract data for detached signing,
+attach an externally produced signature, add timestamps or unauthenticated
+blobs to an existing signature, and remove an embedded signature.
+
+Supported input formats include PE files such as EXE, DLL, and SYS, CAB,
+CAT, MSI, APPX, and several script file types, including `.ps1`, `.ps1xml`,
+`.psc1`, `.psd1`, `.psm1`, `.cdxml`, `.mof`, and `.js`.
+
+The program supports these common workflows:
+
+- direct signing of an unsigned file
+- detached signing via `extract-data`, `sign`, and `attach-signature`
+- post-sign timestamping with `add`
+- verification of embedded signatures or catalog signatures with `verify`
+
+If no subcommand is given, `sign` is assumed.
+
+# FORMATS
+
+Support is not identical across all file formats.
+
+In particular, detached-signature workflows, nested signatures, catalog-based
+verification, and signature removal are format-dependent features.  A command
+that is valid for one supported file type may be unsupported for another.
+
+CAT files are a special case.  They are detached catalog containers for
+hashes of other files, not ordinary embedded-signature payloads.  A CAT
+file is itself a PKCS#7 structure containing authenticated entries for one
+or more external files.  In practice, the catalog signs file digests
+recorded in the catalog, rather than embedding a signature into each
+covered file.
+
+Because of this, CAT files behave differently from embedded-signature
+formats.  They do not support `attach-signature`, `remove-signature`,
+`extract-data`, or nested signatures.
+
+MSI files are also a special case.  They support an extended signature mode
+controlled by `-add-msi-dse`.  In this mode, the MSI signature covers file
+metadata as well as file content.  Detached-signing workflows and any later
+re-signing or nesting operations must use a mode consistent with the MSI
+file's existing signature structure.
+
+# COMMANDS
+
+## `sign`
+
+Create a new Authenticode signature.
+
+This command can sign a normal unsigned file, or it can sign PKCS#7 data
+previously produced by `extract-data`.
+
+## `extract-data`
+
+Extract the PKCS#7 content to be signed later.  This is used for detached
+signing workflows.
+
+## `add`
+
+Add unauthenticated attributes to an existing signature, typically an
+Authenticode timestamp, an RFC 3161 timestamp, or an unauthenticated blob.
+
+With `-index`, the selected signature in a multi-signature file is updated.
+
+## `attach-signature`
+
+Attach a detached PKCS#7 signature to an input file.
+
+With `-nest`, the new signature is attached as a nested signature instead of
+replacing the primary one, if the file format supports nested signatures.
+
+## `extract-signature`
+
+Extract the embedded PKCS#7 signature from a signed file.
+
+## `remove-signature`
+
+Remove the embedded signature from a signed file.
+
+## `verify`
+
+Verify an embedded signature or a catalog signature.
+
+Verification may include digest consistency, certificate chain validation,
+certificate revocation checking, timestamp validation, and optional checking
+of the signer's leaf certificate hash.
+
+When verifying that a file is covered by a catalog, use `verify -catalog
+catalog.cat -in file`.  Verifying the CAT file by itself validates the
+catalog signature; verifying with `-catalog` checks whether the specified
+input file is covered by that catalog.
+
+# OPTIONS
+
+Some options are available only in particular builds or OpenSSL versions.
+In particular, `-askpass` is build-dependent, `-provider` and `-nolegacy`
+require OpenSSL 3, and engine-related options depend on engine support in the
+build.
+
+## General options
+
+`--help`  
+: Show help text.  With a subcommand, show help for that subcommand.
+
+`-v`, `--version`  
+: Show version information.
+
+`-in` *file*  
+: Input file.
+
+`-out` *file*  
+: Output file.  Required for all commands except `verify`.
+
+`-verbose`  
+: Produce more detailed diagnostic output.
+
+## Signing material
+
+`-pkcs12` *file*  
+: Read the signing certificate and private key from a PKCS#12 container.
+
+`-certs`, `-spc` *file*  
+: Read the signing certificate chain.  The historical alias `-spc` is accepted.
+
+`-key` *file-or-URI*  
+: Read the private key.  This may also be a store or PKCS#11 URI.
+
+`-ac` *file*  
+: Add extra certificates to the signature block.
+
+`-pass` *password*  
+: Password or PIN for the key, token, or PKCS#12 container.
+
+`-readpass` *file*  
+: Read the password or PIN from *file*.  Use `-` to read from standard input.
+
+`-askpass`  
+: Prompt for the password interactively.
+
+## PKCS#11, engines, and providers
+
+`-pkcs11module` *module*  
+: Path to a PKCS#11 module.
+
+`-pkcs11cert` *URI*  
+: PKCS#11 URI identifying the certificate object.
+
+`-provider` *provider*  
+: OpenSSL 3 provider to load.  This is the preferred modern interface for
+  provider-based PKCS#11 use.
+
+`-engine`, `-pkcs11engine` *engine*  
+: OpenSSL engine identifier or path to a dynamic engine module.  This
+  interface is retained for compatibility with builds and deployments that
+  still support engines.
+
+`-login`  
+: Force login to the token for engine-based PKCS#11 use.
+
+`-engineCtrl` *command*[:*parameter*]  
+: Pass a control command to the selected engine.
+
+`-nolegacy`  
+: On OpenSSL 3 builds, do not automatically load the legacy provider.
+
+## Signature contents and digest control
+
+`-h` `md5` | `sha1` | `sha2` | `sha256` | `sha384` | `sha512`  
+: Select the digest algorithm.  The default is `sha256`.  `sha2` and
+  `sha256` are equivalent.
+
+`-n` *description*  
+: Description of the signed content.
+
+`-i` *URL*  
+: Informational URL associated with the signed content.
+
+`-comm`  
+: Use Microsoft Commercial Code Signing purpose instead of the default
+  individual purpose.
+
+`-jp` `low`  
+: Add the Java CAB permission attribute.  Only `low` is currently supported.
+
+`-ph`  
+: Generate page hashes for executable files.
+
+`-add-msi-dse`  
+: For MSI files, enable the `MsiDigitalSignatureEx` signing mode.  In this
+  mode, the signature covers MSI metadata as well as file content.  The
+  metadata portion includes stream names, sizes, and selected timestamps in
+  the MSI structure.  This option changes the MSI signature format and should
+  be used consistently in any detached-signing workflow involving
+  `extract-data`, `sign`, `attach-signature`, or `add`.
+
+  For a newly signed MSI, this mode is generally preferred because it extends
+  signing coverage beyond file content alone.  For an already signed MSI,
+  however, the chosen mode must match the file's existing signature
+  structure.  Switching between basic MSI signing and `MsiDigitalSignatureEx`
+  during re-signing or nested-signature operations can invalidate the
+  existing signature.
+
+`-pem`  
+: Write PKCS#7 output in PEM format instead of DER.
+
+## Timestamping and network options
+
+The following timestamping modes are **mutually exclusive** within a single
+`sign` or `add` invocation:
+
+- Authenticode timestamping with `-t`
+- RFC 3161 timestamping with `-ts`
+- built-in RFC 3161 timestamp generation with `-TSA-certs` and `-TSA-key`
+
+`-t` *URL*  
+: Add an Authenticode timestamp from the specified URL.  May be repeated.
+
+`-ts` *URL*  
+: Add an RFC 3161 timestamp from the specified URL.  May be repeated.
+
+`-p` *proxy*  
+: Proxy used for timestamp or CRL retrieval.
+
+`-noverifypeer`  
+: Do not verify the TLS certificate of the remote timestamp service.
+
+`-HTTPS-CAfile` *file*  
+: PEM bundle used to verify HTTPS peers contacted by `osslsigncode`.
+
+`-HTTPS-CRLfile` *file*  
+: PEM CRL file used while verifying HTTPS peers.
+
+`-TSA-certs` *file*  
+: PEM certificate chain for locally generated RFC 3161 timestamps.
+
+`-TSA-key` *file-or-URI*  
+: Private key for locally generated RFC 3161 timestamps.
+
+`-TSA-time` *unix-time*  
+: Timestamp time for locally generated RFC 3161 responses.
+
+## Nested signatures and indexed operations
+
+`-nest`  
+: Add a nested signature instead of replacing the primary signature.
+
+`-index` *n*  
+: Select a signature by index for `add` or `verify`.  Index 0 is the primary
+  signature.
+
+## Unauthenticated blob options
+
+`-addUnauthenticatedBlob`  
+: Add an unauthenticated blob to the signature.
+
+`-blobFile` *file*  
+: Read blob contents from *file*.  If omitted, a placeholder blob is created.
+
+## Verification options
+
+`-c`, `-catalog` *file*  
+: Verify the input file against the specified catalog file.
+
+`-CAfile` *file*  
+: PEM bundle of trusted CA certificates for signer validation.
+
+`-CRLfile` *file*  
+: PEM file containing CRLs for signer validation.
+
+`-TSA-CAfile`, `-untrusted` *file*  
+: PEM bundle of trusted CA certificates for timestamp validation.
+
+`-TSA-CRLfile`, `-CRLuntrusted` *file*  
+: PEM file containing CRLs for timestamp validation.
+
+`-time`, `-st` *unix-time*  
+: Verification time.  If a valid timestamp is present and used, chain
+  validation is normally performed at the timestamp time.
+
+`-ignore-timestamp`  
+: Skip verification of the timestamp signature.
+
+`-ignore-cdp`  
+: Do not fetch CRLs from CRL Distribution Points.
+
+`-ignore-crl`  
+: Disable CRL retrieval and CRL validation.
+
+`-require-leaf-hash` *alg*:*hex*  
+: Require the signer's leaf certificate to hash to the specified value.
+  The hash is computed over the DER encoding of the leaf certificate.
+
+# EXIT STATUS
+
+`0`  
+: Success.
+
+non-zero  
+: Failure.
+
+# DIAGNOSTICS
+
+Common causes of failure include:
+
+missing CA trust bundle  
+: On Unix-like systems, `verify` expects a readable CA bundle, either from
+  `-CAfile` or from a detected system default.
+
+detached-signing mismatch  
+: `extract-data`, `sign`, and `attach-signature` must use compatible
+  digest-affecting options such as `-h`, and where relevant `-ph` and
+  `-add-msi-dse`.
+
+unsupported format feature  
+: Some file formats do not support every subcommand or every signature mode.
+
+missing TSA trust chain  
+: Timestamp verification may fail unless the appropriate TSA trust anchors
+  are supplied with `-TSA-CAfile`, and where needed `-TSA-CRLfile`.
+
+conflicting timestamp modes  
+: `-t`, `-ts`, and built-in TSA signing cannot be combined in one command.
+
+MSI signature mode mismatch  
+: Re-signing or nesting an MSI signature must be consistent with whether the
+  file already uses `MsiDigitalSignatureEx`.  Mixing modes may invalidate the
+  existing signature.
+
+# ENVIRONMENT
+
+`HTTP_PROXY`, `http_proxy`  
+: Default proxy for HTTP access if `-p` is not given.
+
+`HTTPS_PROXY`, `https_proxy`  
+: Default proxy for HTTPS access if `-p` is not given.
+
+`OPENSSL_ENGINES`  
+: May help OpenSSL find engine modules.
+
+# FILES
+
+On Unix-like systems, `osslsigncode` tries common CA bundle locations for
+its default `-CAfile`, including:
+
+- `/etc/ssl/certs/ca-certificates.crt`
+- `/etc/pki/tls/certs/ca-bundle.crt`
+- `/usr/share/ssl/certs/ca-bundle.crt`
+- `/usr/local/share/certs/ca-root-nss.crt`
+- `/etc/ssl/cert.pem`
+
+If no readable CA bundle is available, `verify` may require an explicit
+`-CAfile`.
+
+# NOTES
+
+Use `extract-data` when you need to create a new detached signature object.
+Use `extract-signature` when you need to copy an existing embedded PKCS#7
+signature out of a file.
+
+For safer secret handling, prefer `-readpass` or `-askpass` over `-pass`.
+
+Data added with `-addUnauthenticatedBlob` is not protected by the signature
+and must not be treated as trusted.
+
+For new MSI signatures, `-add-msi-dse` is generally preferred because it
+extends signing coverage to MSI metadata as well as file content.  However,
+it is format-affecting rather than cosmetic, so existing signed MSI files
+should be re-signed only in a mode consistent with their current signature
+structure.
+
+Output files are not overwritten.
+

+  -in app.exe \
+  -out app-signed.exe
+
+osslsigncode verify \
+  -CAfile ca-bundle.pem \
+  -TSA-CAfile tsa-ca-bundle.pem \
+  -in app-signed.exe
+```

+  -readpass p12-pass.txt \
+  -add-msi-dse \
+  -in installer.msi \
+  -out installer-signed.msi
+```
+
+## Use a PKCS#11 provider
+
+```sh
+osslsigncode sign \
+  -provider /path/to/pkcs11prov.so \
+  -pkcs11module /path/to/opensc-pkcs11.so \
+  -pkcs11cert 'pkcs11:token=my-token;object=cert' \
+  -key 'pkcs11:token=my-token;object=key' \
+  -readpass pin.txt \
+  -in app.exe \
+  -out app-signed.exe
+```
+
+## Add a timestamp to an already signed file
+
+```sh
+osslsigncode add \
+  -ts "https://tsa.example.net/" \
+  -in app-signed.exe \
+  -out app-signed-ts.exe
+```
+
+## Verify that a file is covered by a catalog
+
