Class Wrapper

java/com/jcraft/jsch/IdentityRepository.java:52–114

JSch will accept ciphered keys, but some implementations of IdentityRepository can not. For example, IdentityRepository for ssh-agent and pageant only accept plain keys. The following class has been introduced to cache ciphered keys for them, and pass them whenever they are de-ciphered.

   * whenever they are de-ciphered.
