Necron B

Necron B is a next-generation secure storage solution that delivers 100% unbreakable encryption using One-Time Pad and Quantum Randomness, so your files stay safe anywhere — even in the cloud or when shared.

It looks and feels like a sleek USB drive, but it’s your personal vault for digital files — trusted by professionals who cannot afford breaches (lawyers, accountants, journalists, developers).

With Necron B, your files are:

  • Encrypted to 100% unhackable strength — not 99.99% but absolute.

  • Safe to store anywhere — on your computer, an external drive, or even in the cloud.

  • Shareable — transmit encrypted files to others, who can unlock them only with the paired key device.

Why is Necron 100% secure?

Unlike conventional encrypted drives that rely on algorithms which can eventually be broken,
Necron B uses true One-Time Pad encryption with quantum-random keys stored only on a hardware dongle.

One-Time Pad (OTP) Encryption

Uses keys as long as the files themselves, mathematically proven to be unbreakable. Each key segment is used once and never reused, making decryption without the key impossible. OTP is the ultimate in post quantum cryptography (PQC)

Quantum Random Number Generation (QRNG)

Keys are created using a quantum optical measurements device for true quantum randomness, not predictable algorithms. This ensures your encryption keys are completely random.

Hardware-Isolated Key Storage

The encrypted files are stored on your devices or in the cloud. This means they are physically separated from the key which resides only on the Necron USB dongle with its own secure chip and keypad.

Frequently asked questions

How much data can I encrypt ?

The Necron B Key has a capacity of 115GB. To put that into perspective: that's about 40 million pages of text or around 50,000 high-resolution images.
If you need more storage, please contact us about our enterprise solutions.
What if I lose my key ?

If you buy a paired Kit, the Reader Key will act as a backup. But if you didn't buy the Kit you can still order a read-only backup key later. So your encrypted files will never get lost.
We keep a backup for 2 years and can extend this for a small fee.
Can I purchase multiple read-only keys ?

Yes, you can share your encrypted files with multiple trusted people. Just order as many Reader Keys as you need. This works the same way as ordering a backup device.

Why does the Necron dongle have a keypad if the encryption is so secure?

The keypad is just an extra layer of security. While the encrypted files are unhackable, you don't want your key dongle to fall into the wrong hands. Think of it as wearing belt AND braces.
