Convert CRL PEM to XML

See more PEM Examples

Loads a CRL (Certificate Revocation List) from the PEM file format and converts to XML to allow for visual examination and parsing.

Note: This example requires Chilkat v9.5.0.77 or greater.

Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // This example requires Chilkat v9.5.0.77 or greater.

        fmt.Println(pem.LastErrorText())
        pem.DisposePem()
        return
