18 | Linking strongSwan statically or dynamically with other modules is making a | |
19 | combined work based on strongSwan. Thus, the terms and conditions of the GNU | |
20 | General Public License cover the whole combination. | |
21 | ||
22 | In addition, as a special exception, the copyright holders of strongSwan give | |
23 | you permission to combine strongSwan with free software programs or libraries | |
24 | that are released under the GNU LGPL and with code included in the standard | |
25 | release of the OpenSSL project's OpenSSL library under the OpenSSL or SSLeay | |
26 | licenses (or modified versions of such code, with unchanged license). You may | |
27 | copy and distribute such a system following the terms of the GNU GPL for | |
28 | strongSwan and the licenses of the other code concerned, provided that you | |
29 | include the source code of that other code when and as the GNU GPL requires | |
30 | distribution of source code. | |
31 | ||
32 | Note that people who make modified versions of strongSwan are not obligated to | |
33 | grant this special exception for their modified versions; it is their choice | |
34 | whether to do so. The GNU General Public License gives permission to release a | |
35 | modified version without this exception; this exception also makes it possible | |
36 | to release a modified version which carries forward this exception. | |

39 | The DES implementation in the des plugin and the Blowfish implementation in the | |
40 | blowfish plugin are under a BSD style license (see source files for details). | |
41 | Note that these parts have an advertising clause in it. | |
42 | ||
43 | The MD4 and MD5 implementations in the md4 and md5 plugins are from RSA Data | |
44 | Security Inc., so this package must include the following phrase: | |
d50b9be5 | 45 | "derived from the RSA Data Security, Inc. MD5 Message-Digest Algorithm". |
