The following code:
FileInfo pubKey = new FileInfo("pub.rsa");
EncryptionKeys encryptionKeys = new EncryptionKeys(pubKey);
FileInfo file = new FileInfo("example.csv.sig");
PGP pgp = new PGP(encryptionKeys);
pgp.VerifyClearFile(file);
returns an error
System.IO.IOException: 'unknown PGP public key algorithm encountered'
How can I fix this? Is it possible to use pub.rsa public key format there at all?
