Member Function Documentation

ClampSize()

size_t KDF2_RNG::ClampSize ( size_t  req ) const

inline

Definition at line 3571 of file integer.cpp.

GenerateBlock()

void KDF2_RNG::GenerateBlock ( byte *  output, size_t  size  )

inlinevirtual

Generate random array of bytes.

Parameters

output	the byte buffer
size	the length of the buffer, in bytes

All generated values are uniformly distributed over the range specified within the the constraints of a particular generator.

Note

A derived generator must override either GenerateBlock() or GenerateIntoBufferedTransformation(). They can override both, or have one call the other.

Reimplemented from RandomNumberGenerator.
