A simple, yet powerful encryption program. I originally wrote it so that I could keep my passwords written down in my notebook; a notebook which is often left laying about. With the passwords written down in encrypted format, I was free to leave them insecure, the only requirement being the security of the key used to encrypt and decrypt the passwords. Even I can remember a single key.
The problem I had with most encryption programs is that the resulting output is 8-bit ASCII characters. While this is fine for file-based encryption, it’s not so good if you want to be able to write down the encrypted result, or pass it along to a friend in an email. Some encryption programs will present the results in HEX which is an improvement, but it results in encrypted messages that are really long. With encryptadoro, the decrypted result consists of lower- and upper-case letters, numbers, periods, and hyphens; all characters that are easy to write and the increase in the encrypted message length is minimized.
encryptadoro makes use of triple DES encryption in CBC mode. The encryption routines were written by Paul Treo and are used here with his permission. To find out more about DES encryption and Paul’s implimentaion of it, visit: http://www.tero.co.uk/des/explain.php
