Export an Encrypted PKCS #8 Private Key as Encoded Text

See more Private Key Examples

Demonstrates the Chilkat PrivateKey.GetPkcs8EncryptedENC method, which exports the key as password-protected PKCS #8 DER and encodes the encrypted DER as text. The first argument names the binary encoding and the second is the password. The cipher is selected by Pkcs8EncryptAlg.

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.
