Detailed Description

Randomness Pool.

This class can be used to generate pseudorandom bytes after seeding the pool with the Put() methods

Member Function Documentation

void RandomPool::GenerateBlock (  byte *  output, unsigned int  size )  [virtual]

generate random array of bytes Default implementation is to call GenerateByte() size times. Reimplemented from RandomNumberGenerator. Definition at line 94 of file randpool.cpp.

unsigned int RandomNumberGenerator::GenerateBit (   )  [virtual, inherited]

generate new random bit and return it Default implementation is to call GenerateByte() and return its parity. Reimplemented in PublicBlumBlumShub. Definition at line 83 of file cryptlib.cpp. References RandomNumberGenerator::GenerateByte().

void RandomNumberGenerator::DiscardBytes (  unsigned int  n  )  [virtual, inherited]

generate and discard n bytes Default implementation is to call GenerateByte() n times. Reimplemented in ARC4_Base. Definition at line 114 of file cryptlib.cpp. References RandomNumberGenerator::GenerateByte().
