public OpenSSLRandom()

Method Detail

engineSetSeed

protected void engineSetSeed(byte[] seed)

Description copied from class: SecureRandomSpi

Reseeds this SecureRandomSpi instance with the specified seed. The seed of this SecureRandomSpi instance is supplemented, not replaced.

Specified by:

engineSetSeed in class SecureRandomSpi

Parameters:

seed - the new seed.

engineNextBytes

protected void engineNextBytes(byte[] bytes)

Description copied from class: SecureRandomSpi

Generates and stores random bytes in the given byte[] for each array element.

Specified by:

engineNextBytes in class SecureRandomSpi

Parameters:

bytes - the byte[] to be filled with random bytes.

engineGenerateSeed

protected byte[] engineGenerateSeed(int numBytes)

Description copied from class: SecureRandomSpi

Generates and returns the specified number of seed bytes, computed using the seed generation algorithm used by this SecureRandomSpi.

Specified by:

engineGenerateSeed in class SecureRandomSpi

Parameters:

numBytes - the number of seed bytes.

Returns:

the seed bytes

seedOpenSSLPRNGFromLinuxRNG

public static void seedOpenSSLPRNGFromLinuxRNG()

Obtains a seed from the Linux RNG and mixes it into the OpenSSL PRNG (default RAND engine).

NOTE: This modifies the OpenSSL PRNG shared by all instances of OpenSSLRandom and other crypto primitives offered by or built on top of OpenSSL.
