Encrypt and decrypt text using AES-256 encryption with secure key derivation.
0 characters · Ctrl+Enter to encrypt
All three are secure. The key size is saved inside the message, so decrypting never asks for it.
Everything happens in your browser. Nothing is sent to any server. Messages are encrypted with AES-GCM using a key derived from your password (PBKDF2-SHA256, 600,000 rounds, random salt). AES-GCM also detects if a message was altered. If the password is lost, the message cannot be recovered.
AES-256 encryption is military-grade security used by governments and enterprises to protect sensitive data. The AES Encryptor tool brings this level of security to your personal and professional communications. AES (Advanced Encryption Standard) is the most widely used encryption algorithm worldwide. AES-256 uses a 256-bit key, making it virtually impossible to crack with brute force even with powerful computers. This tool is suitable for protecting confidential information, sensitive communications, financial data, and personal documents. Our AES Encryptor uses AES-256-GCM (Galois/Counter Mode), which provides both encryption and authentication. This means the encrypted text cannot be modified without detection. The tool uses PBKDF2 key derivation, which converts your password into a cryptographic key that's resistant to dictionary attacks. How it works: enter your text and a password, choose encryption or decryption mode, and instantly generate encrypted or decrypted results. The encrypted output is encoded in Base64 format for safe transmission via email or text. Share the encrypted message and your password securely (through separate channels), and the recipient can decrypt it using this same tool. The encryption happens entirely in your browser with no server-side processing. Your data never leaves your computer. No passwords or encrypted messages are stored, logged, or transmitted to any server.
Yes, AES-256 is military-grade encryption used by governments and is considered unbreakable with current technology.
No, share the password through a separate, secure channel. Never share both together as it defeats encryption.
Only if they share the correct password. The encryption is impossible to break without the password.
No, all encryption happens in your browser. Nothing is stored, logged, or sent to any server.
