0.32    Wed Apr 15 14:52:28 JST 2026

        Applied a series of patches from cpan [...] schmirler.de
        (https://rt.cpan.org/Public/Bug/Display.html?id=175921):

        - Crypt::SMIME now requires OpenSSL 3.0 or newer.
        - Decryption: Handle the new smime-type value "authEnveloped-data"
          in isEncrypted().
        - Encryption: Add an optional "cipher" argument to encrypt(...),
          defaulting to "AES-128-CBC" as before. Pass e.g. "AES-128-GCM" to
          encrypt with a modern AEAD cipher.
        - Signing: To tell a peer that we support AEAD ciphers we should
          advertise them in the SMIMECapabilities signed attribute. As of
          OpenSSL 3.5 AES-GCM is not part of the default list. Now we
          advertise AES-256-GCM, AES-128-GCM, AES-256-CBC, and AES-128-CBC.
        - Checking: Added the new function "getCapabilities(...)" to get
          the SMIMECapabilities a peer sent us. Note that SMIMECapabilities
          may not only contain ciphers but also hash algorithms.

        Applied a patch from cpan [...] schmirler.de
        (https://rt.cpan.org/Public/Bug/Display.html?id=175923):

        - Added a new method setVerifyFlags($flags) with the flags
          Crypt::SMIME::CRL_CHECK and Crypt::SMIME::CRL_CHECK_ALL to enable
          checking CRLs.

        - Use RFC-5652 CMS functions instead of PKCS#7 ones for better
          interoperability,  Suggested by Hib Engler <h [...]
          killercool.net>.  CMS has a backwards compatibility with
          PKCS#7 so the change should introduce no compat issues.
        - Use AES-128-CBC instead of DES-EDE3-CBC for encryption,
          suggested by the same person.
