Symetric file encryption based on OTP implemented as XOR encryption
OTP (One Time Pad) In case you have any questions, contact me at: crypto-munition@gmx.de
When used correctly, the OTP is an information-theoretically secure and demonstrably non-breakable encryption. The encryption process is implemented as symmetrical file encryption based on 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...
