Edit report at https://bugs.php.net/bug.php?id=80870&edit=1 ID: 80870 User updated by: bugs at jth dot net Reported by: bugs at jth dot net Summary: base64_decode: Concatenated base64 blocks are corrupted Status: Not a bug Type: Bug Package: Strings related Operating System: Linux PHP Version: 7.4.16 Assigned To: cmb Block user comment: N Private report: N New Comment: I may agree, but I am relating to a world outside my control, not an ideal world. Previous Comments: ------------------------------------------------------------------------ [2021-03-17 20:34:20] rtrtrtrtrt at dfdfdfdf dot dfd argue whatever you want: "Concatenated base64 blocks" are idiotic ------------------------------------------------------------------------ [2021-03-17 20:32:13] bugs at jth dot net The base64_decode is handling the padding character '=' incorrectly. It can decode concatenated blocks if the statement i = 0; is inserted into the code in a proper place. However, adding a few more lines will handle it properly and I am currently testing this. ------------------------------------------------------------------------ [2021-03-17 16:27:17] cmb@php.net base64_encode() is supposed to decode a base64 encoded string. Two concatenated base64 encoded strings are not a base64 encoded string. ------------------------------------------------------------------------ [2021-03-16 20:13:29] iguv dot jdzx at ghjj dot sddr again: read the source of roundcubemail which is written in php and solved your issues ------------------------------------------------------------------------ [2021-03-16 19:33:01] bugs at jth dot net Please, forget the source, and relate to the problem. Linux base64 is handling decoding correctly. base64_decode is not handling it correctly, but corrupting data. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
