Encrypt or decrypt text with password-based AES-GCM in your browser.
SecurityEnter the text you want to encrypt in the input field.
Set a strong password (passphrase) that only you know.
Click 'Encrypt' to get the ciphertext. Copy and store it safely.
To decrypt, paste the ciphertext, enter the same password, and click 'Decrypt'.
Encrypt private notes, credentials, or personal information before saving them in cloud storage or note-taking apps.
Encrypt a message before sending it through an insecure channel and share the password separately.
Encrypt sensitive configuration files, API keys, or database dumps before storing them in backups.
Quickly encrypt environment variables or secrets to share safely with teammates without exposing plaintext values.
AES-256 Encrypt/Decrypt lets you encrypt sensitive text with a password using AES-256-GCM — one of the strongest encryption standards — entirely in your browser. No data ever leaves your device.

Compute MD5, SHA-1 and SHA-256 text digests for comparison, not password storage.
Estimate password strength from the tool's scoring model; crack times are illustrative.
Generate time-based one-time codes from your secret and matching algorithm settings.
Compare digest strings or compute a text/file hash; a match does not prove the source is trusted.
Mask recognized personal-data patterns, then review the result for missed information.
Generate passwords using patterns, character rules or a built-in passphrase word list.
