Set .pfx/.p12 Safe Bag Attributes

See more PFX/P12 Examples

Demonstrates how to set safebag attributes in a .pfx/.p12. This example creates a .pfx from a .pem containing a private key and certificates, but also sets PFX safebag attributes before writing the .pfx. Swift

    //  The private key is an ECDSA private key.
    //  The private key is associated with the 1st certificate.
    //  The 2nd certificate is the issuer of the 1st certificate.
