static EncryptedContentInfo | createCRSCompatibleEncryptedContentInfo(OBJECT_IDENTIFIER contentType, AlgorithmIdentifier contentEncryptionAlgorithm, OCTET_STRING encryptedContent) |
static EncryptedContentInfo | createPBE(PBEAlgorithm keyGenAlg, Password password, byte[] salt, int iterationCount, KeyGenerator.CharToByteConverter charToByteConverter, byte[] toBeEncrypted)
Creates a new EncryptedContentInfo, where the data is encrypted
with a password-based key.
|
byte[] | decrypt(Password pass, KeyGenerator.CharToByteConverter charToByteConverter)
Decrypts the content of an EncryptedContentInfo encrypted with a
PBE key.

Parameters: keyGenAlg The algorithm for generating a symmetric key from a password, salt, and iteration count. password The password to use in generating the key. salt The salt to use in generating the key. iterationCount The number of hashing iterations to perform while generating the key. charToByteConverter The mechanism for converting the characters in the password into bytes. If null, the default mechanism will be used, which is UTF8. toBeEncrypted The bytes to be encrypted and stored in the EncryptedContentInfo. Before they are encrypted, they will be padded using PKCS padding.
Parameters: pass The password to use in generating the PBE decryption key. charToByteConverter The converter for converting the password characters into bytes. May be null to use the default.
Returns: The decrypted contents of the EncryptedContentInfo. The contents are first unpadded using the PKCS padding mechanism.
