Method Detail

adoptSecret

public TlsSecret adoptSecret(TlsSecret secret)

Adopt the passed in secret, creating a new copy of it..

Specified by:

adoptSecret in interface TlsCrypto

Parameters:

secret - the secret to make a copy of.

Returns:

a TlsSecret based the original secret.

createCipher

protected abstract TlsCipher createCipher(TlsCryptoParameters cryptoParams,
                                          int encryptionAlgorithm,
                                          int macAlgorithm)
                                   throws java.io.IOException

Create a cipher for the specified encryption and MAC algorithms.

See enumeration classes EncryptionAlgorithm, MACAlgorithm for appropriate argument values.

Parameters:

cryptoParams - context specific parameters.

encryptionAlgorithm - the encryption algorithm to be employed by the cipher.

macAlgorithm - the MAC algorithm to be employed by the cipher.

Returns:

a TlsCipher implementing the encryption and MAC algorithm.

Throws:

java.io.IOException

createEncryptor

protected abstract TlsEncryptor createEncryptor(TlsCertificate certificate)
                                         throws java.io.IOException

Return an encryptor based on the public key in certificate.

Parameters:

certificate - the certificate carrying the public key.

Returns:

a TlsEncryptor based on the certificate's public key.

Throws:

java.io.IOException
