Parameters

const TDesC8 & aDataToBeSigned	The data content or its hash to be signed.
TBool aIsHash	Indicates whether the first parameter is a hash.
const CDSAPrivateKey & aKey	The DSA private key used to sign.
CCmsSignerIdentifier * aSignerIdentifier	The signer identifier. Ownership of the signer identifier is taken by this newly created signer info object.
