Public Member Functions | |
virtual byte | GenerateByte ()=0 |
generate new random byte and return it | |
virtual unsigned int | GenerateBit () |
generate new random bit and return it | |
virtual word32 | GenerateWord32 (word32 a=0, word32 b=0xffffffffL) |
generate a random 32 bit word in the range min to max, inclusive | |
virtual void | GenerateBlock (byte *output, unsigned int size) |

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 GenerateByte(). |
|
generate random array of bytes Default implementation is to call GenerateByte() size times. Reimplemented in NonblockingRng, and RandomPool. Definition at line 88 of file cryptlib.cpp. References GenerateBlock(), and GenerateByte(). Referenced by GenerateBlock(), and DL_GroupParameters_DSA::GenerateRandom(). |
|
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 DiscardBytes(), and GenerateByte(). Referenced by DiscardBytes(). |
