Sun Microsystems, Inc. 2550 Garcia Avenue Mountain View, California 94043 Using the Software This software is not used by default unless PJMEDIA_HAS_ALAW_ULAW_TABLE is disabled. When PJMEDIA_HAS_ALAW_ULAW_TABLE is enabled (the default setting), a table based alaw/ulaw conversion will be used instead. CRC32 Algorithm Software CRC32 algorithm Author Unknown Location pjlib-util/crc32.c License This software is put in public domain, and can be used for any purpose with no warranty: This is an implementation of CRC32. See ISO 3309 and ITU-T V.42 for a formal specification This file is partly taken from Crypto++ library (http://www.cryptopp.com) and http://www.di-mgt.com.au/crypto.html#CRC. Since the original version of the code is put in public domain, this file is put on public domain as well. Using the Software This code is needed by the STUN implementation in PJNATH and can not be disabled. MD5 Hashing Algorithm Software MD5 hashing implementation Author Written by Colin Plumb in 1993 based on MD5 algorithm by Ron Rivest, no copyright is claimed. Location pjlib-util/md5.c Description MD5 hashing for digest authentication. License This software is put in public domain, and can be used for any purpose with no warranty: This code implements the MD5 message-digest algorithm. The algorithm is due to Ron Rivest. This code was written by Colin Plumb in 1993, no copyright is claimed. This code is in the public domain; do with it what you wish. Equivalent code is available from RSA Data Security, Inc. This code has been tested against that, and is equivalent, except that you don't need to include two pages of legalese with every copy. To compute the message digest of a chunk of bytes, declare an MD5Context structure, pass it to MD5Init, call MD5Update as needed on buffers full of bytes, and then call MD5Final, which will fill a supplied 16-byte array with the digest. Using the Software This code is needed by SIP digest authentication procedure, and can not be disabled. SHA1 Encryption Software SHA1 encryption Authors Steve Reid, James H. Brown, Saul Kravitz, Ralph Giles Location pjlib-util/sha1.c License This software is put in public domain, and can be used for any purpose with no warranty: SHA-1 in C By Steve Reid 100% Public Domain ----------------- Modified 7/98 By James H. Brown Still 100% Public Domain ----------------- Modified 4/01 By Saul Kravitz Still 100% PD Modified to run on Compaq Alpha hardware. ----------------- Modified 07/2002 By Ralph Giles Still 100% public domain Using the Software This code is needed by the STUN implementation in PJNATH and can not be disabled. Third Party Software with Licensing Requirements The use of Third Party Software below will require compliance of the licensing requirements of the Third Party Software. You must make sure that your software meets the licensing requirements of the third party libraries below. Some third party libraries may require attributions to be placed in the software, significant portion of the software, and/or in the accompanying documentation. GNU Getopt Software Command line parsing library, part of GNU LIBC Author Copyright (C) 1987,88,89,90,91,92,93,94,96,97 Free Software Foundation, Inc. Location pjlib-util/getopt.[hc] Description Command line parsing library that is used by our sample applications. License Distributed under opensource GNU LGPL. Using the Software This code will only be linked if applications explicitly call pj_getopt() or pj_getopt_long(). Normally application doesn't need to use this, since this functionality is useful for command line/console types of applications only. Milenage and Rijndael Software Milenage Author The implementation was taken from 3GPP TS 35.206 V7.0.0 document. Location third_party/milenage/ Description Milenage algorithm is used for AKAv1-MD5 and AKAv2 SIP digest authentication. License Please consult 3GPP TS documents The 3GPP authentication and key generation functions (MILENAGE) have been developed through the collaborative efforts of the 3GPP Organizational Partners. They may be used only for the development and operation of 3G Mobile Communications and services. There are no additional requirements or authorizations necessary for these algorithms to be implemented. Using the Software The Milenage and Rijndael implementation will only be linked with application if AKA authentication is used and application explicitly calls or makes reference to pjsip_auth_create_aka_response() function. libSRTP Software libSRTP Author David A.
