OTP4U
One Time Pad for you!


OTP4U is a tool that allows the users to easily exchange a random key between them and then use it as a key for a One Time Pad cipher (if the key comes from a true random number generator, the One Time Pad is an unbreakable cipher).
See how it works.

OTP4U help
Sysepub comes with the GNU GPL license.

OTP4U is an open project and is under development: if you want to participate, here are some things to do: GUI, adding a CSPRNG (possibly an existing one), improving the performance. If you are interested, or have any proposal, contact me.
If you'd like to implement an open source version of the OTP4U algorithm in a language different from Java, send it to me! I'll publish it on my website.

Take a look at Sysepub : it gave me the idea for OTP4U

Take also a look at my previous applet: JaVi (Java Vigenere)
