ISAAC (cipher)

ISAAC (indirection, shift, accumulate, add, and count) is a cryptographically secure pseudorandom number generator and a stream cipher designed by Robert J. Jenkins Jr. in 1993.[1] The reference implementation source code was dedicated to the public domain.[2]

"I developed (...) tests to break a generator, and I developed the generator to pass the tests. The generator is ISAAC."[3]
