Method Detail

secureRandom

public static org.springframework.security.crypto.keygen.BytesKeyGenerator secureRandom()

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

secureRandom

public static org.springframework.security.crypto.keygen.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.

shared

public static org.springframework.security.crypto.keygen.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.

string

public static org.springframework.security.crypto.keygen.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.
