From f347c8d7771bc1252ec2d8915a4f9d8204792fd7 Mon Sep 17 00:00:00 2001 From: Bastian Germann Date: Wed, 20 Nov 2024 16:00:01 +0100 Subject: [PATCH] epee: Drop unused in-tree MD5 The RSA-MD licensed implementation that originated from RFC 1321 and got into epee via Cyrus SASL and libEtPan! is not a good fit for epee, which also links to the GPL licensed readline. RSA-MD has an advertisement clause that is known to be incompatible with GPL. --- contrib/epee/include/md5_l.h | 96 --------- contrib/epee/include/md5_l.inl | 352 ------------------------------- contrib/epee/include/md5global.h | 77 ------- 3 files changed, 525 deletions(-) delete mode 100644 contrib/epee/include/md5_l.h delete mode 100644 contrib/epee/include/md5_l.inl delete mode 100644 contrib/epee/include/md5global.h diff --git a/contrib/epee/include/md5_l.h b/contrib/epee/include/md5_l.h deleted file mode 100644 index ffb8c5944..000000000 --- a/contrib/epee/include/md5_l.h +++ /dev/null @@ -1,96 +0,0 @@ -/* - * libEtPan! -- a mail stuff library - * - * Copyright (C) 2001, 2005 - DINH Viet Hoa - * All rights reserved. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.
