"Crypto" - a password generator based on the Java™ programming language
"Crypto" is a little software that synthesizes a set of character sequences of arbitrary length
based on a single keyword. The underlying algorithm is deterministic, hence the output sequences
are not random-generated and may be reproduced by re-processing the keyword. The main purpose of
this software is to be used as a password-generator, deriving a set of highly complex passwords
from a single input string (master password). The character sequences are generated during
runtime and will not be stored, making the use of this software quite save.
Users should bear
in mind that, as at any encryption method, the "cryptographic strength" of the generated sequences
depends on the length and complexity of the input string rather than the size of the generated
sequences. It is well possible to synthesize a set of 30 character passwords from a single letter
input. Those passwords would, however, be extremely weak and easy to crack. Details on the subject
of "password strength" can be found at the WWW (e.g. Wikipedia).
Since I got asked by
some people about the safety of the download, I decided to remove the Crypto application from my
web page. So, if you want to give "Crypto" a try or if you are interested in getting its main
Java™-class "PwdGenerator" to use it for your own projects, just send me an e-mail. I will then
forward to you a copy of that package fresh from my hard-drive.
