Using ECDSA with SignedXML #27

Closed zosocanuck closed 2 years ago

zosocanuck commented 2 years ago

Hi,

I'm getting the following error when attempting to sign XML with an ECDSA keypair:

Unhandled exception. System.Security.Cryptography.CryptographicException: Failed to create signing key.
   at System.Security.Cryptography.Xml.SignedXml.ComputeSignature()

Any ideas?

After taking a look at the reference source of System.Security.Cryptography.Xml.SignedXml class I would say it currently supports only RSA and DSA algorithms. However quick DuckDuckGo search pointed me to blogpost ECDSA and Custom XML Signatures in .NET that may help you.
