Why One Time Pad?
Unlike modern encryption that relies on mathematical difficulty, OTP encryption is information-theoretically secure. A ciphertext can decode to any possible message of the same length, making brute force meaningless. As long as your key is random, at least as long as your message, and never reused — the encryption is unbreakable.
