protected byte[] engineGenerateSeed(int numBytes)

Implements abstract java.security.SecureRandomSpi.engineGenerateSeed.

Doc from java.security.SecureRandomSpi.engineGenerateSeed.

Returns the given number of seed bytes. This call may be used to seed other random number generators.

Parameters
numBytes:int

the number of seed bytes to generate.

Returns:byte[]

the seed bytes.

engineNextBytesback to summary
protected void engineNextBytes(byte[] bytes)

Implements abstract java.security.SecureRandomSpi.engineNextBytes.

Doc from java.security.SecureRandomSpi.engineNextBytes.

Generates a user-specified number of random bytes.

Some random number generators can only generate a limited amount of random bytes per invocation. If the size of bytes is greater than this limit, the implementation should invoke its generation process multiple times to completely fill the buffer before returning from this method.

Parameters
bytes:byte[]

the array to be filled in with random bytes.

engineSetSeedback to summary
protected void engineSetSeed(byte[] bytes)

Implements abstract java.security.SecureRandomSpi.engineSetSeed.

Doc from java.security.SecureRandomSpi.engineSetSeed.

Reseeds this random object with the given seed. The seed supplements, rather than replaces, the existing seed. Thus, repeated calls are guaranteed never to reduce randomness.

Parameters
bytes:byte[]

the seed.
