Member Function Documentation

virtual unsigned char* decaf::security::SecureRandomSpi::providerGenerateSeed

(

int

numBytes

)

[pure virtual]

Generates a new set of seed bytes, the returned value may be used to seed another Random Number Generator.

The caller owns the returned array and must delete it.

Parameters:

numBytes

The number of bytes that should be generated for the new seed array.

Implemented in decaf::internal::security::SecureRandomImpl, and decaf::internal::security::SecureRandomImpl.

virtual void decaf::security::SecureRandomSpi::providerNextBytes	(	unsigned char *	bytes,
		int	numBytes
	)		[pure virtual]

Generates the number of random bytes specified by the size parameter and write them to the passed bytes array.

The array must have already been allocated and be of the correct size to prevent segmentation faults.

Parameters:

bytes	The array that will be filled with random bytes equal to size.
numBytes	The number of bytes to generate and write into the bytes array.

Implemented in decaf::internal::security::SecureRandomImpl, and decaf::internal::security::SecureRandomImpl.

virtual void decaf::security::SecureRandomSpi::providerSetSeed	(	const unsigned char *	seed,
		int	size
	)		[pure virtual]

Reseed the Random Number Generator, the value given supplements the previous seed value if any instead of replacing it.

Parameters:

seed	The array of bytes used to update the generators seed.
size	The size of the passed byte array.

Implemented in decaf::internal::security::SecureRandomImpl, and decaf::internal::security::SecureRandomImpl.
