Why is the SILC Client and SILC Server distributed in SILC Toolkit?
They are not actually. The SILC Client and SILC Server code is distributed in SILC Toolkit merely as example code for how to use the SILC Toolkit. The SILC Client and SILC Server distirbutions may include different code than what is found in the SILC Toolkit distribution. You should not use the client and server found in SILC Toolkit in production environment, but treat them merely as example applications.
