AES Encrypt & Decrypt — AES-256-GCM Password Encryption in Browser

Cách dùng

1. 1 Pick Encrypt or Decrypt.
2. 2 Enter your password — use the strength meter as a rough guide.
3. 3 Paste plaintext (encrypt) or Base64 ciphertext (decrypt), then click the action button.
4. 4 Copy the output. The password never leaves your browser.

Vì sao dùng công cụ này

• AES-256-GCM authenticated encryption — tampering is detected, unlike raw AES-CBC.
• PBKDF2-SHA256 with 100,000 iterations slows offline brute-force attacks on weak passwords.
• Random 16-byte salt and 12-byte IV per encryption — same plaintext + password produces different output every time.
• Pure WebCrypto — runs in your browser, no servers see your password or plaintext.

Câu hỏi thường gặp

AES Encrypt & Decrypt là gì?

An AES Encrypt & Decrypt tool is a tool that encrypts and decrypts text using AES-256-GCM with a user-supplied password. It derives the encryption key from the password using PBKDF2 with SHA-256, providing authenticated encryption that detects tampering. All cryptographic operations run entirely client-side in the browser, so plaintext, passwords, and ciphertext are never sent to a server.
