Features

Military-Grade Encryption

AES-256 encryption with authenticated modes, secure key derivation, and portable payloads — all running in your browser.

AES-GCM Encryption

Authenticated encryption with AES-256-GCM. Ciphertext integrity is verified automatically — tampered payloads are rejected.

One-Click Decrypt

Paste the JSON payload and enter the password. Algorithm, salt, and IV are embedded — no manual configuration needed.

Password Generator

Generate cryptographically secure passwords with configurable length and character sets. Entropy meter shows real strength.

PBKDF2 Key Derivation

Passwords are never used directly. PBKDF2 with 100,000 SHA-256 iterations and a random salt derives the encryption key.

Portable Payloads

Output is a self-describing JSON object with version, algorithm, salt, IV, and ciphertext. Share via any text channel.

Web Crypto API

All cryptographic operations use the browser's native SubtleCrypto interface. Hardware-accelerated, audited, and battle-tested.

How It Works

Simple as 1-2-3.

No sign-ups, no installs. Just open the tool and start working.

01

Enter a Password

Type any password. PBKDF2 derives a 256-bit key using 100,000 SHA-256 iterations and a random salt.

02

Encrypt Your Text

Choose AES-GCM or AES-CBC, enter your plaintext, and get a portable JSON payload with ciphertext, IV, and salt.

03

Share Securely

Copy the payload and share via any channel. Only someone with the correct password can decrypt it.

Use Cases

Who Uses This? Everyone.

From professionals to students, real people solving real problems every day.

Developers

Config secrets

Encrypt API keys, tokens, and credentials before committing to repos or sharing in documentation.

Privacy Users

Secure messaging

Encrypt sensitive messages before sending over email, Slack, or any unencrypted channel.

DevOps

Environment variables

Encrypt .env values for safe storage in version control. Decrypt at deploy time with a shared password.

Security Teams

Incident response

Encrypt forensic data and investigation notes. Share payloads with team members who have the password.

Journalists

Source protection

Encrypt notes and source identities. The JSON payload can be stored anywhere without revealing content.

Everyone
