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 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:
NotInitializedException
java.security.GeneralSecurityException
InvalidBERException
