// Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
// by calling UnlockBundle.  It requires a Bundle unlock code.

// It requires the bundle to be unlocked, as shown above.

// If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
