It looks to me that in the 5.2 library, there are no equivalents to the 5.0 calls
NR<SHA>::Verifier::GetDigestSignatureScheme() NR<SHA>::Signer::GetDigestSignatureScheme() It looks like digest signatures are deprecated, but I have to maintain backward compatibility. So it looks like I can't upgrade to 5.2 yet. I need to have a version of my software that reads digest signatures but writes message signatures. I can use 5.0 to make that. Then after a while I can release a 5.2 upgrade and deprecate the old file format. Do I understand correctly?
