## Detailed Description

Interface for accumulating messages to be signed or verified.

Only Update() should be called from the PK_MessageAccumulator() class. No other functions inherited from HashTransformation, like DigestSize() and TruncatedFinal(), should be called.

## Member Function Documentation

## ◆ DigestSize()

unsigned int PK_MessageAccumulator::DigestSize | ( |  | ) | const
| inline virtual

Warning
  DigestSize() should not be called on PK_MessageAccumulator

Implements HashTransformation.

Definition at line 2869 of file cryptlib.h.

## ◆ TruncatedFinal()

void PK_MessageAccumulator::TruncatedFinal | ( | byte * | digest,
|  | size_t | digestSize
| ) |  |
| inline virtual

Warning
  TruncatedFinal() should not be called on PK_MessageAccumulator

Implements HashTransformation.
