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.

  final pfx = CkPfx();

  // The file path is relative to the application's current working directory.  An absolute path
  // may also be used.  Supply the path appropriate to your own environment.
  // The PFX password should come from a secure source rather than being hard-coded.
  final password = 'myPfxPassword';

    pfx.loadPfxFile('qa_data/identity.pfx', password);

  // Encrypt the exported private keys.  Supported algorithms include aes128, aes192, aes256, and 3des;
