OTP4U
OTP4U is a tool that allows 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). Since version 0.9.3 a CSPRNG (Cryptographically Secure Pseudo Random Number Generator) is used to generate the keys of the cipher.
