Unlike most encryption methods that rely on mathematical problems which could one day be solved by powerful computers or quantum technology, the One-Time Pad (OTP) is fundamentally different.

It is mathematically proven to be unbreakable when used correctly.

With a One-Time Pad, every message is combined with a truly random key that is exactly the same length as the message and used only once.

Because the key is completely random and never reused, the resulting encrypted data (ciphertext) contains no pattern to analyze — even a quantum computer cannot find a relationship between the encrypted text and the original message.

In short:

• No passwords to guess.

• No algorithms to break.

• No backdoors, no server access, and no tracking.

• 100 % privacy — guaranteed by math, not by trust.

Onecryption is built entirely around this principle:

All keys are generated locally, all encryption happens on your device, and only you and your chosen contact ever hold the key.

That’s why we say:

It’s not “military-grade.” It’s mathematically unbreakable.
