To find the current status of particular files, you have to read the copyright notices at the top of the files. . A list of the supported algorithms, their origins, and exceptions to the above licensing: . AES The implementation of the AES cipher (also known as rijndael) is written by Rafael Sevilla. Assembler for x86 by Rafael Sevilla and Niels Möller, Sparc assembler by Niels Möller. . ARCFOUR The implementation of the ARCFOUR (also known as RC4) cipher is written by Niels Möller. . ARCTWO The implementation of the ARCTWO (also known as RC2) cipher is written by Nikos Mavroyanopoulos and modified by Werner Koch and Simon Josefsson. . BLOWFISH The implementation of the BLOWFISH cipher is written by Werner Koch, copyright owned by the Free Software Foundation. Also hacked by Simon Josefsson and Niels Möller. . CAMELLIA The C implementation is by Nippon Telegraph and Telephone Corporation (NTT), heavily modified by Niels Möller. Assembler for x86 and x86_64 by Niels Möller. . CAST128 The implementation of the CAST128 cipher is written by Steve Reid. Released into the public domain. . CHACHA Implemented by Joachim Strömbergson, based on the implementation of SALSA20 (see below). Assembly for x86_64 by Niels Möller. . DES The implementation of the DES cipher is written by Dana L. How, and released under the LGPL, version 2 or later. . GOSTHASH94 The C implementation of the GOST94 message digest is written by Aleksey Kravchenko and was ported from the rhash library by Nikos Mavrogiannopoulos. It is released under the MIT license. .

Assembly for x86_64 and ARM by Niels Möller. . SERPENT The implementation of the SERPENT cipher is based on the code in libgcrypt, copyright owned by the Free Software Foundation. Adapted to Nettle by Simon Josefsson and heavily modified by Niels Möller. Assembly for x86_64 by Niels Möller. . POLY1305 Based on the implementation by Andrew M. (floodyberry), modified by Nikos Mavrogiannopoulos and Niels Möller. Assembly for x86_64 by Niels Möller. .
