OTP-Crypto-Tool
Symetric file encryption based on OTP implemented as XOR encryption
...The integrated pseudo-random generator serves only to illustrate and check the functionality. The use of this generator for REAL OTPs is not recommended.
For REAL OTPs, hardware-based key generators (e.g. thermal noise of a pn junction, transistor or diode), white noise (e.g. out of tune radio) or other stochastic decay processes should be used.
If used correctly, it cannot be decrypted by any intelligence service.
