Free Encrypt Text With Password Locally
Encrypt text with password locally no tracking. Uses PBKDF2 key derivation and Web Crypto API — zero server uploads.
What does this tool do? Encrypt any text with a password so only someone with the same password can
read it. Like putting your message in a digital vault. Your data and password never leave your
device.
Military-grade AES-256 encryption — 100% local
View Technical Specifications (For Developers)
- Algorithm: AES-256-GCM via
crypto.subtle - Key Derivation: PBKDF2 with SHA-256, 100,000 iterations, random 16-byte salt
- IV: Random 12-byte initialization vector per encryption
- Output: Base64-encoded concatenation of salt + IV + ciphertext
All encryption is performed locally using AES-256-GCM via the Web Crypto API. Your data never
leaves your browser.
