Encrypt Text Online Free

Encrypt text with a password using AES-GCM.

lock Encrypt Text Online Free
verified_user Your files are processed only as needed and are not stored after the tool finishes.
Encrypt text with a password and create a compact encrypted payload that can be decrypted later with the matching password. This tool uses AES-GCM for authenticated encryption and PBKDF2 to derive a strong encryption key from your password and a random salt. It is useful for temporary secrets, notes, configuration snippets, or sharing sensitive text through channels where you want an extra layer of protection. The encrypted payload includes the salt and nonce needed for decryption, but not the password. Text is processed in memory and no content is stored.

Frequently Asked Questions

Can the text be decrypted without the password? expand_more
No. Keep the password safe; the tool cannot recover it.
What algorithm is used? expand_more
AES-GCM with a 256-bit key derived from your password using PBKDF2-SHA256 with 100,000 iterations and a random salt.
