Add base64 encoded signed certificate to a Stringlist (Stringlist class)

[Requires Janus Network Security]

This callable method signs an X.509 certificate request and adds the lines of the signed certificate to the end of a Stringlist. It requires a valid private key and certificate request.

Syntax

[%rc =] sl:AppendSignedCertificate( [PrivateKey=] string, [Request=] string, - [[Signer=] string], - [[StartDate=] string], - [[EndDate=] string], - [[SerialNumber=] number], - [SignatureAlgorithm= digestAlgorithm])

Syntax terms

%rc An, optional, numeric variable that is set to zero if the function is a success. The possible return codes are described below in Return codes.
sl A Stringlist object.
PrivateKey This name allowed argument is a string or Stringlist that contains the private key to be used for signing. The key length may be a maximum of 4096 bits (as of version 7.7 of Model 204). The pre-7.7 maximum is 2048.
Request This name allowed argument is a string or Stringlist that contains the base64 encoded X.509 certificate request.
Signer This optional, name allowed, argument is a string or Stringlist that contains the base64 encoded CA (certifying authority) X.509 certificate. If not specified, the Request value is used: that is, the certificate will be self-signed.
StartDate This optional, name allowed, argument is a string that contains the Start date for the signed certificate (in YYMMDDHHMISS format). The default is today's date.
EndDate This optional, name allowed, argument is a string that contains the End date for the signed certificate (in YYMMDDHHMISS format). The default is 24 hours from StartDate. YY may not be less then the current 2-digit year.
SerialNumber This optional, name allowed, argument is a numeric value that is the Serial number for the signed certificate. The default is a number guaranteed to increase by 1 for every call and guaranteed to increase from run to run, unless there is an extreme amount of signing occurrences.
SignatureAlgorithm This optional, name required, argument is a DigestAlgorithm enumeration value. Valid values are: MD5, SHA1, SHA256, SHA384 (Model 204 7.7 and later), and SHA512 (Model 204 7.7 and later). The default value is SHA256 as of Model 204 7.7 (and zap maintenance for versions 7.6 and 7.5).

Note: Although supported and formerly the default, most modern browsers are deprecating SHA1.

Return codes

0 All is well.
7 Insufficient storage.
10 Private key Stringlist identifier missing.
11 Invalid private key Stringlist identifier.
12 Invalid private key Stringlist data (not correctly base64 encoded).
13 Certificate request Stringlist identifier missing.
14 Invalid certificate request Stringlist identifier.
15 Invalid certificate request.
16 Invalid CA certificate Stringlist identifier.
17 Invalid CA certificate.
18 Invalid start date.
19 Invalid end date.
20 Invalid serial number.
21 Private key does not match signer public key.

Usage notes

For some background information concerning certificates, see Public-key cryptography and Certificate signing request.

Examples

This example uses a self-generated private key and certificate request and simply displays the AppendSignedCertificate base64 encoded output.

b %sl is object stringlist %ls is longstring %cr is longstring %sc is longstring %rc is float %ls = %(System):GeneratedPrivateKey(Length=512) %cr = %ls:CertificateRequest %sl = new %rc = %sl:appendSignedCertificate(%ls, %cr) %sl:print end

The result is:

-----BEGIN X509 CERTIFICATE----- MIHvMIGaAgkA3narlNAAAAkwDQYJKoZIhvcNAQELBQAwADAeFw0xNjAzMzAyMDQ3 MjVaFw0xNjAzMzAyMDQ3MjVaMAAwWjANBgkqhkiG9w0BAQEFAANJADBGAkEAxFfX HX5yDlQg/Jp/fA2KqZqpuz/N+Ga1vrGs3+RSQ5zjrwjkyg9Ltd8pHgvcvnCt38MV BqoqWKDOXU/kVRaYCQIBAzANBgkqhkiG9w0BAQsFAANBAG8BPhU1lLQFGGW2TZon MrzOypC/ztchIxU3CSUFCSRaD6h5N6b6DmLVKnHgbiUPZEDqZ0sSqy6mrOd9yI/2 zPg= -----END X509 CERTIFICATE----- 8

You can use the following statements to somewhat "unpack" the base64 result, but the resulting element names are not very meaningful:

%sc = %sl:pemToString('X509 CERTIFICATE') %sc:derToXmlDoc:print

The result is:

%sc:derToXmlDoc:print: <Sequence> <Sequence> <Integer>16030188579305029648</Integer> <Sequence> <ObjectIdentifier>1.2.840.113549.1.1.11</ObjectIdentifier> <Null/> </Sequence> <Sequence/> <Sequence> <UTCTime>20160330214812.000Z</UTCTime> <UTCTime>20160330214812.000Z</UTCTime> </Sequence> <Sequence/> <Sequence> <Sequence> <ObjectIdentifier>1.2.840.113549.1.1.1</ObjectIdentifier> <Null/> </Sequence> <BitString bits="576"> 304602410085C691E0BCB563 ...

The DerToXmlDoc method that is used above does not understand the semantics of the standard tags for the signed certificate items. No SOUL method interprets signed certificate items as well as, for example, the RSAPrivateKeyToXmlDoc does for a private key.
