Create a new HashTransformation to accumulate the message to be signed.
- Parameters
-
rng a RandomNumberGenerator derived class
- Returns
- a pointer to a PK_MessageAccumulator
NewSignatureAccumulator() can be used with all signing methods. Sign() will automatically delete the accumulator pointer. The caller is responsible for deletion if a method is called that takes a reference.
Implements PK_Signer.
