Text Encryption Tool
This tool lets you scramble a message into unreadable text and reverse it back to the original whenever you need it. Encryption transforms your words using a chosen method or key, so that anyone who sees the result without that key just sees meaningless characters. Decryption applies the process in reverse to restore the readable message. Everything runs in your browser, and nothing you type is stored or sent to a server.
People reach for simple text encryption to add a layer of privacy to notes, share a message that only the intended reader can unlock, or learn how classic ciphers work. It is a practical way to keep casual prying eyes away from text you paste into a document, an email body, or a chat where you also share the key separately.
How to use it
Enter your text, choose to encrypt or decrypt, and provide a key or passphrase if the method requires one. Copy the output and keep the key safe, because without it the message cannot be recovered. For genuinely sensitive material such as passwords or financial records, rely on dedicated, audited security software; treat this tool as a convenient, lightweight way to obscure everyday text.
