Decrypt a JWE with a Private Key

See more JSON Web Encryption (JWE) Examples

Demonstrates Jwe.SetPrivateKey, which sets the private key used to decrypt a recipient of a loaded JWE.

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.
