LibTorrent Copyright (C) 2005-2014, Jari Sundell LICENSE GNU GPL, see COPYING. "libtorrent/src/utils/sha_fast.{cc,h}" is originally from the Mozilla NSS and is under a triple license; MPL, LGPL and GPL. An exception to non-NSS code has been added for linking to OpenSSL as requested by Debian, though the author considers that library to be part of the Operative System and thus linking is allowed according to the GPL. Use whatever fits your purpose, the code required to compile with Mozilla's NSS implementation of SHA1 has been retained and can be compiled if the user wishes to avoid using OpenSSL.
