Public Methods

public static BytesKeyGenerator secureRandom ()

Create a BytesKeyGenerator that uses a SecureRandom to generate keys of 8 bytes in length.

public static BytesKeyGenerator secureRandom (int keyLength)

Create a BytesKeyGenerator that uses a SecureRandom to generate keys of a custom length.

Parameters
keyLength the key length in bytes, e.g. 16, for a 16 byte key.

public static BytesKeyGenerator shared (int keyLength)

Create a BytesKeyGenerator that returns a single, shared SecureRandom key of a custom length.

Parameters
keyLength the key length in bytes, e.g. 16, for a 16 byte key.

public static StringKeyGenerator string ()

Creates a StringKeyGenerator that hex-encodes SecureRandom keys of 8 bytes in length. The hex-encoded string is keyLength * 2 characters in length.
