SILC Random Number Generator is cryptographically strong pseudo random
 number generator. It is used to generate all the random numbers needed
 in the SILC sessions. All key material and other sources needing random
 numbers use this generator.

 The interface provides functions for retrieving different size of
 random number and arbitrary length of random data buffers. The interface
 also defines Global RNG API which makes it possible to call any
 RNG API function without specific RNG context.
