Compliant code

The application sets a secure expiration time for digital certificates

                resource {
  certificate-id {
    ca-profile: "ca-profile-name";
    challenge-password: {secretpassword};
    re-generate-keypair: mykey;
    validity-period: 365;
  }
}

            

Non compliant code

The application does not define a secure limit for expiration of certificates

                resource {
  certificate-id {
    ca-profile: "ca-profile-name";
    challenge-password: "password";
    re-generate-keypair: mykey;
    validity-period: 3000;
  }
}

            

Requirements
