Member Function Documentation

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 111 of file cryptlib.cpp. References RandomNumberGenerator::GenerateByte().

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

generate random array of bytes Default implementation is to call GenerateByte() size times. Reimplemented in NonblockingRng, BlockingRng, and RandomPool. Definition at line 116 of file cryptlib.cpp. References RandomNumberGenerator::GenerateByte(). Referenced by DL_GroupParameters_DSA::GenerateRandom().

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 142 of file cryptlib.cpp. References RandomNumberGenerator::GenerateByte().
