About AES Encrypt / Decrypt
Encrypt text with AES-256-GCM authenticated encryption using a password. Decrypt previously encrypted messages with the same password.
How It Works
Derives a 256-bit AES key from your password using PBKDF2 (100,000 iterations with SHA-256). Encrypts with AES-GCM which provides both confidentiality and authenticity. Output includes salt + IV + ciphertext in Base64.
Step by Step
- 1 Enter the text to encrypt (or ciphertext to decrypt)
- 2 Enter your password in the second input
- 3 Select Encrypt or Decrypt mode
- 4 Click to process
- 5 Copy the result — share it safely
Tips
- Use a strong password — the encryption is only as strong as your password
- AES-GCM detects tampering — modified ciphertext will fail to decrypt
- Save the password separately from the encrypted text
- 100K PBKDF2 iterations protect against password brute-force attacks
Frequently Asked Questions
Is AES-256-GCM secure?
Yes. AES-256-GCM is the gold standard for symmetric encryption — used by governments, banks, and in TLS 1.3. GCM mode provides authenticated encryption.
Can I decrypt on another device?
Yes, as long as you use the same password. The salt and IV are embedded in the ciphertext output, so only the password is needed.
