Does anyone know how to specify a hash algorithm other than MD5 and SHA1 in
the RSAPKCS1SignatureDeformatter class?
The hash algorithm I'm using is an algorithm that concatenates the MD5 and
SHA1 hashes, but whenever I specify the name of my algorithm and call the
VerifySignature method of the RSAPKCS1SignatureDeformatter it throws a
CryptographicUnexpectedOperationException error that tells me it cannot find
"a required object identifier".
