The general crypto exception thrown by all methods of the library is com.didisoft.pgp.PGPException. A quick exception handling solution is to catch only PGPException and log it’s stack trace


try {

...

} catch (com.didisoft.pgp.PGPException e) {

...

}


However the exception cause can be classified further at runtime, thus identifying what exactly has failed. The distinction of the causes is achieved by sub classes of com.didisoft.pgp.PGPException. They must be called earlier than PGPException.


Below is a list of the exceptions that subclass com.didisoft.pgp.PGPException provided by the library. They are all located in the package com.didisoft.pgp.exceptions
