I have a PKCS7 file with signature in the envelope. What API function can I use to open the PKCS7 to extract the signature data and length and then verify the message digest? The verify is shown below assuming I got the signature data and length.
int rc = ECDSA_verify(0, md, 20, signaturedata, signaturelength, pubeckey); Kinda hard to find the right functions which seems to be a pretty common thing. I did search the forum for this. -- View this message in context: http://old.nabble.com/PKCS7-open-and-extract-signature-tp34542036p34542036.html Sent from the OpenSSL - User mailing list archive at Nabble.com. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
