Encrypt a message and share it with a code and a secret key - only someone with both can read it.

This tool encrypts a message and gives you a code plus a secret key to share separately - the recipient needs both the code and the key to decrypt and read the original message. Useful for sharing sensitive information (like a password or private note) more securely than plain text messaging.

Frequently asked questions

If both were sent together in the same message, anyone intercepting that message would have everything needed to decrypt it - sending them through different channels (like the code via email and the key via text) adds a meaningful layer of protection.

Without the key, the encrypted message cannot be decrypted - there is no recovery mechanism, so make sure the key is shared successfully and kept safe until the message is read.

Encryption/decryption is designed to keep the message protected using the key you control - check the specific tool's handling, but the core design principle is that only someone with both the code and key can access the original content.
