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
