Export Selected PFX Contents as PEM

See more PFX/P12 Examples

Demonstrates Pfx.ToPemEx, which exports selected PFX contents as PEM-formatted text with control over which parts are included and how private keys are encrypted.

Background. Private keys are written in PKCS #8 form. Supported key-encryption algorithms include aes128, aes192, aes256, and 3des; leaving the algorithm empty produces unencrypted keys.
