## Member Function Documentation

## ◆ GenerateBlock()

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

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.
