[openssl-users] Converting Bin format to X509 format

[Erwann Abalea]

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.

Cordialement,
Erwann Abalea
