Hello,
I would like to verify a pkcs7 signature from a document, is pkcs7 detached
signature.
I have extracted form the document, the signature is a very long hexadecimal
string.
I used this command but the I get a verification failure.
openssl dgst -verify <publickey> -sha1 -signature
<signaturefile>
Could anyone tell me a way to verify the signature correctly?
