ABOUT:

Omziff is a straightforward encryption utility that uses various cryptographic 
algorithms to encrypt and decrypt textual files. 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!

HISTORY:

Added in v3.0.9
* Fix minor file splitting bug

Added in v3.0.8
* Fixed small bugs

Added in v3.0.6
* Fix sizing issues on large screen resolutions

Added in v3.0.5
* Fix minor interface bug

Added in v3.0.4
* Fix minor bug in file splitter

Added in v3.0.3
* Fix minor bugs

Added in v3.0.2
* Fix small interface bug

Added in v3.0.1
* Hide/Show password.
* More password generator options.
* Fix minor bug in file split sizing.

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!
