STRANDOM is a cryptographically Strong pseudo-RANDOM number generator suitable for cryptographic applications. It expands a random seed of 32*k bits into a pseudo-random sequence of 32*t bits for any k=1,2,3,... and t=1,2,3,... STRANDOM builds itself on the basic compression function of HAVAL. It supports three different levels of security (by defining PASS=3, 4 or 5). Finally, STRANDOM is reasonably fast: when PASS is set to 3, it produces 23.41 mega-bits per second on UltraSparc (200MHz), and 22.99 mega-bits per second on Pentium Pro 180.

STRANDOM is ready for 64-bit platforms.
