Hi, I have the signature string from a signed SAML assertion. I also have the private key file and cert file. I'm trying to decrypt the signature string, so that I can try to see how it compares to the digest in the assertion.
I think that "openssl smime" should be able to do this, using something like: openssl smime -decrypt -in mysignature.txt -inkey myrsa.key -recip myrsa.pem but I'm not sure what the format of the mysignature.txt file should be? When I run "openssl smime", with just the signature string in the file, I get: Error reading S/MIME message 316:error:2107A087:PKCS7 routines:SMIME_read_PKCS7:no content type:./crypto/pkcs 7/pk7_mime.c:222: Here's the signature string that I have: b/UeCFZt9u6MR0w3eEJW1yczC/KQLuOG7ZjN+q76VwKxAgzl+CjHlUkT7YMu3yukroGjj2p5gkeE5057CQgQFxzBpdIdTxntWOvlkpg6eXiFhRFh41iqbWSnBOOwDskp0PXAIajYurCEbDfWILDUKu2t23z3JKr7g8dS3hxlmTA= Can anyone tell me: 1) Should it be possible to do this using openssl? 2) What should I do with the signature string above, to put it into a file that I can then use "openssl smime" to decrypt the string?
