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;
}
}
