CmsMakeEnvDataFromBytes Method

Create a CMS enveloped-data object from data in a byte array.

Namespace: CryptoSysPKI
Assembly: diCrSysPKINet (in diCrSysPKINet.dll) Version: 23.0.0.30549 (23.1.0.0)
Syntax
public static int MakeEnvDataFromBytes(
	string outputFile,
	byte[] inputData,
	string certList,
	CipherAlgorithm cipherAlg = ,
	CmsKeyEncrAlgorithm keyEncrAlg = CmsKeyEncrAlgorithm.Default,
	HashAlgorithm hashAlg = HashAlgorithm.Sha1,
	CmsEnvDataOptions advOptions = CmsEnvDataOptions.None,
	KdfKdfAlg kdfAlg = KdfKdfAlg.X963,
	KdfKeyWrapAlg keyWrapAlg = KdfKeyWrapAlg.Default,
	string keyString = "",
	int count = 0,
	CmsContentEncrAlg contEncrAlg = CmsContentEncrAlg.Aes128
)

Parameters

outputFile  String
Output file to be created
inputData  Byte
Input data.
certList  String
List of one or more recipient X.509 certificate filenames, separated by semicolons (;). A certificate's representation in base64 or as a PEM string may be used instead of a filename. Alternatively, specify a single PKCS#7 certificate chain file (.p7c/.p7b).

Special cases: Set as "type=@pwri" to create a single recipientInfo of the PasswordRecipientInfo (pwri) type; or set as "type=@kekri,keyid=<string>" to create a single recipientInfo of the KEKRecipientInfo (kekri) type. See Remarks.

cipherAlg  CipherAlgorithm  (Optional)
Content encryption algorithm [default=ignored]. Deprecated: use contEncrAlg. (This parameter will be removed in a future update)
keyEncrAlg  CmsKeyEncrAlgorithm  (Optional)
Key encryption algorithm for ktri type [default=RSAES-PKCS-v1_5)]
hashAlg  HashAlgorithm  (Optional)
Hash function where applicable. Must be one of the SHA-* family [default=SHA-1; SHA-256 for RSA-KEM]
advOptions  CmsEnvDataOptions  (Optional)
Advanced options. See CmsEnvDataOptions.
kdfAlg  KdfKdfAlg  (Optional)
Key derivation function (KDF) (where applicable)
keyWrapAlg  KdfKeyWrapAlg  (Optional)
Key wrap algorithm for ECDH key agreement scheme or kekri type (default=match content encryption algorithm)
keyString  String  (Optional)
(formerly ukmString) Use to pass optional additional user key material (ukm) for KDF where KeyAgreement (kari) type or RSA-KEM is used. Or use to pass the password for a pwri type or the key encryption key (KEK) for a kekri type. Either pass a plain ASCII string, e.g. "abc" or use the format "#x<hex-digits>" to pass a string of arbitrary octet values, e.g. "#xdeadbeef01" to pass the 5 bytes 0xde,0xad,0xbe,0xef,0x01. Required for pwri and kekri types.
count  Int32  (Optional)
Optional iteration count for KDF in pwri type (default=4096) or tag length for AuthEnvelopedData (in range 12-16, default=16). Otherwise ignored.
contEncrAlg  CmsContentEncrAlg  (Optional)
Alternative way to specify content encryption algorithm with more options. Takes precedence over cipherAlg. [default=AES128-CBC]

Return Value

Int32
Number of successful recipients or negative error code
