Free normal distribution software for windows

Distribution Guide is a program allowing to build various graphs of statistical distributions.
Distribution Guide will enable you to enter the parameters of a particular distribution and display the graphs of such functions as CDF, PDF and others. Printing support is provided as well.
Supported distributions:
- Exponential
- Lognormal
- Normal
- Weibull
- Uniform
Supported graph types:
- probability density function (PDF)
- cumulative distribution function (CDF)
- survival function
- hazard function
Note: Free for personal use!

Encryption Routine is a strong encryption/decryption routine based on a 4 number keyes random seed distribution hash. This routine was written by the authors wish to try to improve message privacy while sent across the networks.
The Random Keys Distribution Encryption Routine is a strong encryption/decryption routine that is based on a 4 number keys random seed distribution hash.
The command line switches to encrypt are E.g.: C:r7 -a 11111 -b 22222 -c 33333 -d 44444 -e "filename.txt"
The command line switches to decrypt are E.g.: C:r7 -a 11111 -b 22222 -c 33333 -d 44444 -f "filename.txt"
The 4 numbers following the -a -b -c -d switches should have the values between 10000 and 99999. They are the entry seed values and are used instead of the common password protection method. Cyphering strength is high due to use of hashed number table based on 4 function rundom number distribution.
One out of the 4 functions running inside this encryption is used in the Game of life which is listed for download, and it states the diversity of random number distributions produced.

CryptedZIP standalone version is a useful utility that creates a crypted zip and restore a crypted zip to a normal zip.
