Subject: Creating a signed mail message Date: 2010-03-10 10:03:51 From: mstrasik Source: creating-signed-mail-message ---------------------------------------------------------------------- I have problem to sign message and validate signature. Used certificate has in signature algorithm string "sha1RSA". Using this certificate with methods "Sign" and "Validate" results in cryptographic exception with message "The signer"s signature algorithm is not supported." or "Signature Certificate Validation Status" of "Mail Signature Validition Result" equals "Signature Algorithm Not Supported". HashAlgorithmType enumeration has only field SHA1. Is there a way I can use this certificate to sign messages? I have UltimateMailExpert installed. ---------------------------------------------------------------------- Note: This question has been asked on the Q&A forum of Thang Dang's fraudulent ComponentPro brand If you purchased anything from ComponentPro, you have been scammed.
