  • April 12, 2023
    The XML Security Library 1.3.0 release includes the following changes:

    • core xmlsec and all xmlsec-crypto libraries:
      • (ABI breaking change) Added support for the KeyInfoReference Element.
      • (ABI breaking change) Switched xmlSecSize to use size_t by default. Use "--enable-size-t=no" configure option ("size_t=no" on Windows) to restore the old behaviour (note that support for xmlSecSize being different from size_t will be removed in the future).
      • (API breaking change) Changed the key search to strict mode: only keys referenced by KeyInfo are used. To restore the old "lax" mode, set XMLSEC_KEYINFO_FLAGS_LAX_KEY_SEARCH flag on xmlSecKeyInfoCtx or use '--lax-key-search' option for XMLSec command line utility.
      • (API breaking change) The KeyName element content is now trimmed before key search is performed.
      • (API breaking change) Disabled FTP support by default. Use "--enable-ftp" configure option to restore it. Also added "--enable-http" and "--enable-files" configure options to control support for loading files over HTTP or locally.
      • (API/ABI breaking change) Disabled MD5 digest method by default. Use "--enable-md5" configure options ("legacy-crypto" option on Windows) to re-enable MD5.
      • (ABI breaking change) Added "failureReason" file to xmlSecDSigCtx and xmlEncCtx to provide more granular operation failure reason.
      • (ABI breaking change) Removed deprecated functions.
      • Added support for loading keys through ossl-store interface (e.g. for using keys from an HSM). Also see '--privkey-openssl-store' and '--pubkey-openssl-store ' command line options for XMLSec utility.
      • Added ability to control transforms binary chunk size to improve performance (see '--transform-binary-chunk-size' command line option for XMLSec utility).
      • Fixed all potentially unsafe integer conversions and all the other warnings.
      • Added XML Signature 1.1 interop (2012) and XML Encryption 1.1 interop (2012) tests.
    • xmlsec-openssl library:
    • xmlsec-nss library:
    • xmlsec-gnutls library:
    • xmlsec-mscng library:
    • xmlsec-mscrypto library:
      • In maintenance mode starting from this release.
      • Disabled by default support for NT4. Use "nt4=yes" configure option on Windows to re-enable it.
    • xmlsec-gcrypt library:
    • xmlsec command line utility:
      • (API breaking change) The XMLSec command line utility is using 'strict' key search mode by default. To restore the old 'lax' key search mode, use the new '--lax-key-search' option.
      • (API breaking change) The XMLSec command line utility is no longer prints detailed errors by default. To restore the detailed errors, use the new '--verbose' option.
      • Added '--transform-binary-chunk-size' option to control transforms binary chunk size (increasing the chunk size should improve performance at the expense of memory usage.
      • Added support for loading keys through ossl-store interface (e.g. for using keys from an HSM). Also see '--privkey-openssl-store' and '--pubkey-openssl-store ' command line options for XMLSec utility.
      • Added '--enabled-key-info-reference-uris' option to control processing of the the KeyInfoReference Element.
      • Added '--pbkdf2-key' option for loading PBKDF2 keys.
      • Added '--concatkdf-key' option for loading ConcatKDF keys.
      • Added '--hmac-min-out-len' option to control the min accepted HMAC Output length.
      • Added '--pubkey-openssl-engine' option to load public keys from OpenSSL engine.
      • Added '--crl-pem' and '--crl-der' options to load CRLs.
      • Added '--verify-keys' option to verify key's certificate before loading into Keys Manager (only supported for OpenSSL currently).
      • Enabled templatized output filenames to facilitate batch operations on multiple input files.
