Public Class Cms

The Cms type exposes the following members.

Methods

	Name	Description
	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, CmsEnvDataOptions)	Create a CMS enveloped-data object (default recipient parameters).
	MakeEnvData(String, String, String, CipherAlgorithm, CmsKeyEncrAlgorithm, HashAlgorithm, CmsEnvDataOptions, KdfKdfAlg, KdfKeyWrapAlg, String, Int32, CmsContentEncrAlg)	Create a CMS enveloped-data object (advanced options).
	MakeEnvDataFromBytes	Create a CMS enveloped-data object from data in a byte array.
	MakeEnvDataFromString(String, String, String, CipherAlgorithm, CmsEnvDataOptions)	Create a CMS enveloped-data object from an ASCII string (default recipient parameters).
	MakeEnvDataFromString(String, String, String, CipherAlgorithm, CmsKeyEncrAlgorithm, HashAlgorithm, CmsEnvDataOptions, KdfKdfAlg, KdfKeyWrapAlg, String, Int32, CmsContentEncrAlg)	Create a CMS enveloped-data object from an ASCII string (advanced options).
	MakeSigData(String, String, String, String, CmsSigAlg, CmsSigDataOptions)	Create a CMS object of type SignedData from an input data file (advanced options including RSA-PSS).
	MakeSigData(String, String, String, String, HashAlgorithm, CmsSigDataOptions)	Create a CMS object of type SignedData from an input data file using RSASSA-PKCS1V1_5 with options.
	MakeSigDataFromBytes	Create a CMS object of type SignedData from an array of bytes.
	MakeSigDataFromPseudo	Create a SignedData object from a "pseudo" object.
	MakeSigDataFromSigValue	Create a CMS object of type SignedData using a pre-computed signature (advanced algorithms).
	MakeSigDataFromString(String, String, String, String, CmsSigAlg, CmsSigDataOptions)	Create a CMS object of type SignedData from an input string (advanced options including RSA-PSS).
	MakeSigDataFromString(String, String, String, String, HashAlgorithm, CmsSigDataOptions)	Create a CMS object of type SignedData from an input string using RSASSA-PKCS1V1_5 with options.
	QueryEnvData	Query a CMS enveloped-data object file for selected information.
	QuerySigData	Query a CMS signed-data object for selected information.
	ReadComprData	Read and extract the decompressed contents of a CMS compressed-data file.
	ReadEnvDataToBytes	Read and decrypt a CMS enveloped-data object to a byte array.
	ReadEnvDataToFile	Read and decrypt a CMS enveloped-data object to a file.
	ReadEnvDataToString	Read and decrypt a CMS enveloped-data object to a string.
	ReadSigDataToBytes	Read the content from a CMS signed-data object directly into a byte array.
	ReadSigDataToFile	Read the content from a CMS signed-data object file.
	ReadSigDataToString	Read the content from a CMS signed-data object directly into a string.
	VerifySigData	Verify the signature and content of a signed-data CMS object file.
