Win32 :
Linux x86 :
Solaris x86
LRZIP - Long Range ZIP or Lzma RZIP compression program:
Win32 :
Linux x86 :
Solaris x86
Cryptography
OpenSSL 1.0.0 beta3 - a toolkit implementing cryptography standards:
Win32
BCrypt - encrypt and decrypt files using the Blowfish algorithm:
Win32:
Linux x86:
Solaris x86
6Crypt - encrypt and decrypt files using the RSA RC6 algorithm:
Win32 :
Linux x86 :
Solaris x86
MCrypt - encrypt and decrypt files using the MARS algorithm:
Win32 :
Linux x86 :
Solaris x86
RCrypt - encrypt and decrypt using the Rijndael/AES algorithm:
Win32:
Linux x86:
Solaris x86
SCrypt - encrypt and decrypt files using the Serpent algorithm:
Win32 :
Linux x86 :
Solaris x86
TCrypt - encrypt and decrypt files using the Twofish algorithm:
Win32 :
Linux x86 :
Solaris x86
NCrypt - NMRC File Encryptor / Decryptor / Wiper:
Win32 :
Linux x86 :
Solaris x86
NCrypt is a symmetrical file encryptor/decryptor that gives you the choice of three of the candidates for the NIST AES (Rijndael, Serpent, Twofish). A wipe-only option (DoD standard 5220.22-M/Gutmann method) is also available that is indepedent of the encryption process.
File Wiper
NRM - New Remove File Wiper based on NCrypt:
Win32 :
Linux x86 :
Solaris x86
NRM uses the same flags and syntax as the UNIX 'rm' command, but wipes files thirty-five times using the Gutmann method.
Graphics
XV - an interactive image manipulation program for the X Window System:
Linux x86 :
Solaris x86
XV can operate on images in the GIF, JPEG, TIFF, PBM, PGM, PPM, XPM, X11 bitmap, Sun Rasterfile, Targa, RLE, RGB, BMP, PCX, FITS, and PM formats on all known types of X displays.
