Thanks, but I don't want to create a certificate, I want to sign a
string with an certifikate. I can do this with

  openssl rsautl -sign

But then I have a signed string, but the Information about the signing
certificate ist lost. If I had a pkcs7 certificate as the result of the
signing process, the sigining certificate would be included in the
result.
