Further information
1. This function is used to decrypt a document that has been encrypted using RSAprivencrypt. It requires the public part of the key used for encryption.
2. If the key file name does not include an explicit path ( e.g. "somekey"), it is searched for in the default public keys directory located at getparam("ssl_dir")+"/pubkeys" instead of the current working directory. It is required to prefix the key file name with "./" in order to access a key file from the current directory ( e.g. "./somekey").
