Cms Class

• GetSigDataDigest
  • Extract the message digest from a signed-data CMS object file and verify the signature.
• GetSigHashAlgorithm
  • Find ID of message digest hash algorithm used to make signature.
• MakeComprData
  • Create a new CMS compressed-data file (.p7z) from an existing input file.
• MakeDetachedSig
  • Create a "detached signature" CMS signed-data object file from a message digest of the content (advanced algorithms).
• MakeEnvData(String, String, String, CipherAlgorithm, Cms.EnvDataOptions)
  • Create a CMS enveloped-data object (default recipient parameters).
• MakeEnvData(String, String, String, CipherAlgorithm, Cms.KeyEncrAlgorithm, HashAlgorithm, Cms.EnvDataOptions, Kdf.KdfAlg, Kdf.KeyWrapAlg, String, Int32, Cms.ContentEncrAlg)
