These algorithms include: Blowfish, Cast128, Gost, IDEA, Misty1, AES/Rijndael, and Twofish. Omziff also generates random passwords, splits files, and does simple file shredding according to DOD Standards. It is freeware, comes in a standalone executable file with no dependencies and is completely USB compatible!

Added in v3.0.0 * Utility to quickly append one file to the end of another one. * Decoy file generator. Good for creating a directory full of useless files to obfuscate a hidden, sensitive file. * Cryptographically secure random number generator, which creates secure random numbers with irreproduceable patterns. * Small interface changes. Added in v2.5.5 * Small interface changes Added in v2.5.0 * File Splitter Utility Added in v2.0.0 * Interface redesign * Create file hash Added in v1.0.0 * File shredding function * Maintenance issues Added in v0.0.8.8 * Added prompt to remind user of algorithm used. «§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§»«§§»« ENCRYPTION USAGE: Simply choose both an algorithm and an input file to generate an encrypted output file from, and then process the resulting output file. Omziff also generates random passhrases as well. 1) Simply choose the algorithm that you wish to use in generating an encrypted output file. 2) Then select the file to use to generate the encrypted output from, as well as the filename and location of your new, decrypted output file. 3) If you choose to use a passphrase, use the passphrase generator to create a random one for you. Use the save button to save it as a textfile. 4) Take care to remember which algorithm you used to encrypt your data! PASSWORD GENERATOR USAGE: Use the password generator to create a random password for added security between 3 and 20 characters in length. FILE SHREDDER USAGE: Securely delete single or multiple files in correspondence with Department Of Defense Standard number 5220.22-M. FILE SPLITTER USAGE: Split larger files into smaller segments for various purposes: to store on floppy disks, email, etc. The files are split into segements which you specify the size of, and then the output is portioned off into files with an .oss extension. The main file, which contains the rejoin details, has an .omf extension. Do not modify or delete it!
