I'm trying to verify a signature.
This signature of a document is a very long hexadecimal string, is stored alone in the signaturefile.txt pubfirma.pem is the public key corresponding with the private key used to sign the document I used the next commands to verify the signature: openssl rsautl -verify -in signaturefile.txt -out output.txt -inkey pubfirma.pem -pubin openssl rsautl -verify -in signaturefile.txt -inkey pubfirma.pem -pubin I always receive the same answer: unable to load Public Key The public key is a base64encoded certificate, is only a public key, there is not a private key in the pubfirma.pem All the files are stored in the same directory where I use the openssl command. I can see the details of the x.509 certificate (the public key) using the next command: openssl x509 -in pubfirma.pem -text -noout Any suggestion?
