PK_MessageAccumulator* DL_SignerImpl< SCHEME_OPTIONS >::NewSignatureAccumulator ( RandomNumberGenerator & rng ) const

inlinevirtual

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 autimatically delete the accumulator pointer. The caller is responsible for deletion if a method is called that takes a reference.

Implements PK_Signer.
