Set an FTPS Client Certificate from PEM

See more FTP Examples

Demonstrates the Chilkat Ftp2.SetSslClientCertPem method, which configures a client certificate and private key from PEM. The first argument may be the PEM text or a PEM file path, and the second is the private-key password (empty when the key is not encrypted).

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

Background: This is the PEM-based form of setting the mutual-TLS client certificate — convenient when the certificate and key already live in a .pem file, the common format from OpenSSH and Unix tooling. Use SetSslClientCertPfx instead for a PKCS#12 .pfx/.p12 bundle. As with any client certificate, set it before connecting.
