BeeCrypt is an ongoing project to provide strong and fast cryptography in the form of a toolkit usable by commercial and open source projects. Included in the library are entropy sources, random generators, block ciphers, hash functions, message authentication codes, multiprecision integer routines, and public key primitives.
BEYE (Binary EYE) is a portable advanced file viewer with a built-in editor for binary, hexadecimal, and disassembler modes. It contains a highlighting Java/AVR/i86-AMD64/ARM-XScale/PPC64 disassembler, full preview of MZ, NE, PE, LE, LX, DOS.SYS, NLM, ELF, a.out, arch, coff32, PharLap, and rdoff executable formats, a code guider, and many other features.
e3 is a full-screen, user-friendly text editor with an interface similar to that of either WordStar, Emacs, Pico, Nedit, or vi. It's heavily optimized for size and independent of libc or any other libraries, making it useful for mini-Linux distributions and rescue disks. The assembler version supports Linux, FreeBSD, OpenBSD, NetBSD, Win9x, QNX, Atheos, BeOS, ELKS, and DOS. There is also a separately distributed version written in C which supports some other Unix versions and CygWin. It is also possible to use regular expressions by using child processes like sed. e3 has a built in arithmetic calculator.
The GRASP Project has created an algorithmic-level graphical representation for software called the Control Structure Diagram (CSD). The CSD was created to improve the comprehension efficiency of Ada source code and, as a result, improve software reliability and reduce software costs. Since its creation, the CSD has been expanded and adapted to include other languages. GRASP provides the capability to generate CSD's from Ada 95, C, C++, Java, and VHDL source code in both a reverse and forward engineering mode with a level of flexibility suitable for professional application. GRASP has been integrated with the GNU family of compilers for Ada (GNAT) and C (gcc), and Sun's javac compiler for Java. Use of GRASP is not restricted to these compilers, however. This has resulted in a comprehensive graphically-based development environment for these languages. The user may view, edit, print, and compile source code as CSDs with no discernible addition to storage or computational overhead.
John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. It supports several crypt(3) password hash types commonly found on Unix systems, as well as Windows LM hashes. On top of this, lots of other hashes and ciphers are added in the community-enhanced version (-jumbo), and some are added in John the Ripper Pro.
Over5 is a program for transferring between c64/vic20 machines and Amiga/PC/UNIX boxes. It supports serial transfer at 38400 bps using only a RS-232 level converter and a 3-line standard nullmodem cable. No special serialport chips are needed. Source code is included. It features read/write/execute memory, filecopy with wildcards, read/write raw disk, read/write ZIPCODE archive, the ability to use the Amiga/PC/UNIX box as a harddisk server ($0801-$f600), builtin diskturbo, and a fast basic bootstrap for most cbm 8-bitters.
