Hi Team, Looks like there is a bug while trying to decode a non-encode base64 for 12 characters (or multiple of 12) , the return code is always 0.
e.g:- 1) When trying to decode a encoded value [vardhaman@oc6085028360 ~]$ echo 'Nzc3Nzk5Cg==' | base64 --decode 777799 [vardhaman@oc6085028360 ~]$ echo $? 0 2) A sample when trying to decode a non-encode value [vardhaman@oc6085028360 ~]$ echo '777799' | base64 --decode ����base64: invalid input [vardhaman@oc6085028360 ~]$ echo $? 1 3) Now trying to decode a non-encoded value of 12characters [vardhaman@oc6085028360 ~]$ echo 'vardhamanbn1' | base64 --decode ��݅�����[vardhaman@oc6085028360 ~]$ echo $? 0 The point 3 should return code as 1 , as invalid input I feel this bug is present in all version , anywhere sharing the current version where I tested vardhaman@oc6085028360 ~]$ base64 --version base64 (GNU coreutils) 8.22 Copyright (C) 2013 Free Software Foundation, Inc. -- Thanks & Regards Vardhaman B.N 9945840928
