Frequently Asked Questions

How to encrypt text online for free?▾
Enter your text, choose a password, and click encrypt. The encrypted output can be safely shared — only someone with the correct password can decrypt it.
How to send an encrypted message?▾
Encrypt your message with a password, copy the encrypted output, and send it via email or chat. Share the password separately through a different channel for security.
How to encrypt text with AES?▾
Our tool uses AES (Advanced Encryption Standard), the same algorithm used by governments worldwide. Enter your text, set a password, and get AES-encrypted output instantly.
How secure is AES encryption?▾
AES is the industry standard for symmetric encryption, used by governments and military organizations worldwide. AES-256 would take billions of years to brute-force with current technology.
How to protect sensitive information in messages?▾
Encrypt your sensitive text before sending it. The recipient needs only the password and our decryption tool to read the original message. The encrypted text is unreadable without the password.
How to encrypt a password or secret note?▾
Enter the password or note in the text field, set an encryption password, and encrypt. Store the encrypted output safely — it cannot be read without the decryption password.
