Encryptor
public Encryptor(CryptoToken token,
byte[] keyID,
EncryptionAlgorithm alg)
throws TokenException,
java.security.InvalidKeyException
- Creates an Encryptor on the given CryptoToken, using the key with
the given keyID and algorithm
- Parameters:
token
- The CryptoToken to use for encryption. The key must
reside on this token.keyID
- The keyID of the key to use for encryption. This key
must have been generated on this token with KeyManager.alg
- The EncryptionAlgorithm this key will be used for.
- Throws:
java.security.InvalidKeyException
- If no key exists on this token with this
keyID.
TokenException
encrypt
public byte[] encrypt(byte[] plaintext)
throws CryptoManager.NotInitializedException,
java.security.GeneralSecurityException,
InvalidBERException
- Encrypts a byte array.
- Parameters:
plaintext
- The plaintext bytes to be encrypted.
- Returns:
- The ciphertext. This is actually a DER-encoded Encoding
object. It contains the keyID, AlgorithmIdentifier, and the encrypted
plaintext. It is compatible with the SDRResult created by NSS's
SecretDecoderRing.
- Throws:
CryptoManager.NotInitializedException
java.security.GeneralSecurityException
InvalidBERException
