PemToString (Stringlist function)
Extract base64 encoded PEM data to string (Stringlist class)
[Introduced in Sirius Mods 8.0]
The PEM (Privacy Enhanced Mail) protocol uses base64 encoding for binary data that needs to be transferred and stored as text.
Syntax
%string = sl:PemToString( label, [Occurrence= number]) Throws InvalidPemData
Syntax terms
| %string | A Longstring or String to contain the decoded binary data in the method object, sl. |
|---|---|
| sl | A Stringlist object that contains base64 encoded data. |
| label | The string that identifies the base64 encoded data you want to convert. X509 certificates and CRLs are bounded by the text markers -----BEGIN label----- and -----End label-----.
Note that this is a required, case-sensitive, argument; if it does not match the first and last items of sl, no data is returned to %string. |
| Occurrence | The occurrence number of the requested tag. |
Usage notes
Examples
The following request loads Longstring %ls with the contents of the base64 encoded CRL (Certificate Revocation List) contained in Stringlist %sl:
b %ls is longstring %sl is object stringlist text to %sl = new raw -----BEGIN X509 CRL----- MIIBODCB4zANBgkqhkiG9w0BAQQFADBgMQswCQYDVQQGEwJBVTEMMAoGA1UECBMD UUxEMRkwFwYDVQQKExBNaW5jb20gUHR5LiBMdGQuMQswCQYDVQQLEwJDUzEbMBkG A1UEAxMSU1NMZWF5IGRlbW8gc2VydmVyFw0wMTAxMTUxNjI2NTdaFw0wMTAyMTQx NjI2NTdaMFIwEgIBARcNOTUxMDA5MjMzMjA1WjASAgEDFw05NTEyMDEwMTAwMDBa MBMCAhI0Fw0wMTAxMTUxNjE5NDdaMBMCAhI1Fw0wMTAxMTUxNjIzNDZaMA0GCSqG SIb3DQEBBAUAA0EAHPjQ3M93QOj8Ufi+jZM7Y78TfAzG4jJn/E6MYBPFVQFYo/Gp UZexfjSVo5CIyySOtYscz8oO7avwBxTiMpDEQg== -----END X509 CRL----- end text %ls = %sl:pemToString('X509 CRL') end
