RSA Encryption
Generate an RSA key pair, encrypt a short text with the public key and decrypt it with the private key — good for sending a password or one-time code.
How to use the RSA encryption tool
- Click "Generate new key pair" — you get a public key and a private key.
- Give the public key to whoever will send you a message (it does not need to stay secret). Keep the private key to yourself.
- They paste your public key and their message into the "Encrypt" box, click Encrypt, and send you the result.
- You paste that into the "Decrypt" box together with your private key to read the original message.
