Facing issues with using Openpgp library -

i downloaded openpgp illustration code mentioned in question how utilize php openpgp library?.

i faced next error when tried access keygen.php:

fatal error: phone call undefined method openpgp_message::signature_and_data() in d:\official\data\sites\openpgp\lib\openpgp_crypt_rsa.php on line 145

infact, none of 3 working. can please explain how prepare these issues?

i guess line 148 in https://github.com/singpolyma/openpgp-php/blob/master/lib/openpgp_crypt_rsa.php

must corrected from: $sig = $packet->signature_and_data();

to: $sig = $packet->signatures();
