Interface PGPDataEncryptorBuilder

All Known Implementing Classes:

BcPGPDataEncryptorBuilder, JcePGPDataEncryptorBuilder

public interface PGPDataEncryptorBuilder

A builder for PGPDataEncryptor instances, which can be used to encrypt data objects.

Method Summary

Methods

Modifier and Type	Method and Description
PGPDataEncryptor	build(byte[] keyBytes) Builds a data encryptor using the algorithm configured for this builder.
int	getAlgorithm() The encryption algorithm used by data encryptors created by this builder.
java.security.SecureRandom	getSecureRandom() Gets the SecureRandom instance used by this builder.

Method Detail

getAlgorithm

int getAlgorithm()

The encryption algorithm used by data encryptors created by this builder.

Returns:

one of the symmetric encryption algorithms.

build

PGPDataEncryptor build(byte[] keyBytes)
                       throws PGPException

Builds a data encryptor using the algorithm configured for this builder.

Parameters:

keyBytes - the bytes of the key to use for the cipher.

Returns:

a data encryptor with an initialised cipher.

Throws:

PGPException - if an error occurs initialising the configured encryption.

getSecureRandom

java.security.SecureRandom getSecureRandom()

Gets the SecureRandom instance used by this builder.
If a SecureRandom has not been explicitly configured, a default SecureRandom is constructed and retained by the this builder.
