How Kyber Works

Kyber uses lattice-based cryptography for security against classical computers and quantum computers. Here is the step-by-step process of secure password sharing:

Step 1

Create Session (Recipient)

The person who wants to receive the password creates a Kyber session and gets a public key.

The recipient clicks 'Create Session' and receives a link to share.

Step 2

Share the Link

The recipient sends the link (with public key) to the person who should send the password.

The link can be shared via messenger, email, or QR code.

Step 3

Enter & Encrypt Password (Sender)

The sender opens the link, enters the password, and encrypts it with the public key.

The password is encrypted directly in the browser using Kyber – only the recipient can decrypt it.

Step 4

Retrieve & Decrypt Password

The recipient opens the session page, enters their private key, and decrypts the password.

Only the recipient with the private key can see the password. After that, it is deleted.

How it works – simple explanation

🔑 Recipient creates session

The recipient creates a session and gets a link to share.

📤 Share link & enter password

The sender opens the link, enters the password, and encrypts it directly in the browser.

🔓 Decrypt & view password

The recipient opens the session page, enters their private key, and sees the password.

Important: The password is never stored in plaintext on the server. Only the recipient can decrypt it.
