AES Encrypt/Decrypt
Encrypt and decrypt text using AES-256-GCM with password-based key derivation. All processing happens locally in your browser.
Use the same password for encryption and decryption
Security Details:
- • Algorithm: AES-256-GCM
- • Key Derivation: PBKDF2 with 100,000 iterations
- • Salt: 16 random bytes (stored with ciphertext)
- • IV: 12 random bytes (stored with ciphertext)
- • All encryption happens locally in your browser
AES-256-GCM - Technical Details
AES-256-GCM provides authenticated encryption with 256-bit keys. PBKDF2 with 100,000 iterations derives the key from your password. Each encryption uses a random 12-byte IV and 16-byte salt for security.
