Bonjour, An X.509 certificate is: Certificate ::= SEQUENCE { tbsCertificate TBSCertificate, signatureAlgorithm AlgorithmIdentifier, signatureValue BIT STRING } What you produced with ? openssl rsautl -sign ? is the content of the ? signatureValue ? element (not its BIT STRING structure, only the inner content). What is missing is all the rest, and it can?t be produced by the sole ? openssl x509 ? ? command. Please refine your question.
