Password Manager - Manage your passwords and private information in one secure application for web sites, computers, programs. Search, add, edit, delete, print, etc. Java app, runs everywhere. Uses SunJCE crypto.
...This program can protect very sensitive data, such e-mail, which has size up to 100 kilobytes, but processing speed might be too small with the bigger size of source data.
ProcessingTime(data) = O(data ^ 2);
USE IT ONLY TO PROTECT SMALL FILES (~ 100 Kb or a bit bigger).
You can use "PaperBack" to print your 100 Kb encrypted *.iK file to A4 paper and get strong encrypted digital letter.

A program to generate random reciprocal bigram tables
...The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed.
Executing the program with command-line arguments causes bigram to generate a random bigram table to print to screen or save to disk depending on whether the -f filename argument was given. If the -p passphrase argument is given a specific table is generated and is repeatable each time the same passphrase is given.
This program was written to supplement the Enigma Simulator by Dirk Rijmenants.
