Parameters

outputFile  String

Output file to be created

inputData  String

Input data string, expected plain ASCII text.

certList  String

List of recipient X.509 certificate filename(s), separated by semi-colons (;). 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 type (pwri); or set as "type=@kekri,keyid=<string>" to create a single recipientInfo of the KEKRecipientInfo type (kekri). 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 [default=rsaEncryption)]

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) for ECDH key agreement scheme (where applicable)

keyWrapAlg  KdfKeyWrapAlg  (Optional)

Key wrap algorithm for ECDH key agreement scheme (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. Optional for kari types but 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]
