Save a Private Key as a Traditional PEM File

See more Private Key Examples

Demonstrates the Chilkat PrivateKey.SavePemFile method, which saves the key as unencrypted PEM, preferring a traditional algorithm-specific representation (for example RSA PRIVATE KEY). The only argument is the destination path.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
