If you prefer to use ftp instead of http, ftp://cryptography.org/crypto/9z9Wc2wH/ maps to the same directory. Directories * Blowfish - documentation, sample implementations, and test vectors for the Blowfish block cipher. * BeOS - cryptographic support for this operating system. * Cryptanalysis - crackers for Microsoft Word, PKZIP, etc., plus some generally useful information on cracking weakly encrypted files and passwords. * DES - source code for the NIST Data Encryption Standard in Java, C, and assembly. * DESX - Algorithm description and sample code for DES eXtended. * disk - On-the-fly disk encryption * Enigma - Simulation of the Enigma rotor machine cipher. * feal - reference code for FEAL * file - file encryption utilities * FIPS181 - Federal Information Processing Standard 181 * HASH - MD5, RIPEMD, etc. * IDEA - Intenational Data Encryption Algorithm reference source. * KerbNet - Kerberos network security implementation. * libraries - cryptographic software development libraries * Luc - Lucas public key cryptography demo. * Mac - CryptDisk, Secure Edit, etc., for the Macintosh * Misc - All kinds of interesting unsorted stuff, much of which should be in a different directory. * mpj - programs and source code written by Michael Paul Johnson * Nautilus - Encrypted voice communications software. * network - network security software * new - stuff that has been uploaded to ftp://cryptography.org/pub/incoming that hasn't been sorted, yet. * Password_cracking - especially for Unix. * pcexpo - some cryptographic files from a PC Expo disk. * PEM - Privacy Enhanced Mail * pgp - Pretty Good Privacy, the BEST email encryption/signature solution * pgpfone - Secure voice communications. * redoc - C source code. * RSA - reference implementations & RSA libraries. (Please observe patent restrictions in the USA until September 2000.) * SECDRV - Secure Drive and similar on-the-fly disk utilities. * SKIP * ssh - SSH With Fast x86 DES * SSL - Secure Sockets Layer libraries and plug-ins * Steg - Steganographic (data hiding) programs ------------------------------------------------------------------------ File Encryption * 73,911 atbash2.zip Atbash 2 - small, fast DOS program uses Sapphire II Stream Cipher and produces voice-readable ciphertext. * 176,059 dlock2.zip - This might be the strongest block cipher program in this archive. Check it out yourself. Uses the Diamond2 Block Cipher. For DOS, Unix, or whatever. * 109,692 qcrypt11.zip QuiCrypt - uses the Sapphire II Stream Cipher and 128-bit keys in the registered, secure mode, and the Sapphire Stream Cipher and 40-bit keys in the trial mode. * 29,036 qdcrypt.zip Qdcrypt - exportable companion to QuiCrypt and Qcrypt that only decrypts those file s. Also includes a way to make a self-decrypting executable file to send secure messages to correspondents who may not be comfortable with more conventional utilities. * 12,628 randkey2.zip Random Key generator * 135,083 ruby_m5.zip A small hash-style cipher, built for speed and small size (not good for a cryptographic hash due to its small 64-bit block size) * 54,994 sapphire.zip Description of the Sapphire II Stream Cipher and cryptographic hash, with source code and working encryption program. Encryption Algorithm Libraries * 78,854 diacrypt.zip 32-bit Delphi components for 10-round Diamond2 block cipher, the Sapphire II Stream Cipher with feedback, some good (pseudo)random number generation tools, and also a CRC-32 unit -- all free for the downloading. * 176,059 dlock2.zip Code for Diamond2 (128-bit blocks) and Diamond Lite (64-bit blocks). * 135,083 ruby_m5.zip Small & fast * 54,994 sapphire.zip Stream cipher with feedback, also usable as a cryptographic hash KerbNet This implementation of the Kerberos protocol is available for a variety of platforms.
