Method Detail

createKeyGenerator

public static KeyGenerator createKeyGenerator()

Returns a new AES key generator instance.

Returns:

The AES key generator.

Throws:

RuntimeException - If an AES key generator couldn't be instantiated.

generateKey

public static SecretKey generateKey(int keyBitLength,
                    SecureRandom random)

Generates an AES key of the specified length.

Parameters:

keyBitLength - The key length, in bits.

Returns:

The AES key.

Throws:

RuntimeException - If an AES key couldn't be generated.

createCipher

public static org.bouncycastle.crypto.engines.AESEngine createCipher(SecretKey secretKey,
                                                     boolean forEncryption)

Creates a new AES cipher.

Parameters:

secretKey - The AES key. Must not be null.

forEncryption - If true creates an AES encryption cipher, else creates an AES decryption cipher.

Returns:

The AES cipher.
