Encrypt and decrypt text using military-grade AES encryption with secure key derivation
All encryption and decryption operations are performed locally in your browser. No data is transmitted to any server, ensuring complete privacy and security.
Our encryption tool uses AES-GCM (Advanced Encryption Standard - Galois/Counter Mode) with 256-bit keys for military-grade security. It derives encryption keys from your password using PBKDF2 with 100,000 iterations and SHA-256 hashing. All encryption happens locally in your browser - no data is sent to servers.
To encrypt text: 1) Select the 'Encrypt' mode, 2) Enter your text in the input field, 3) Create or generate a strong password, 4) Click 'Encrypt Now'. The encrypted result appears as JSON containing the encrypted data, initialization vector (IV), salt, and algorithm details. Save both the encrypted data and password securely.
To decrypt: 1) Select the 'Decrypt' mode, 2) Paste the complete encrypted JSON data in the input field, 3) Enter the password used for encryption, 4) Click 'Decrypt Now'. The original text will be revealed in the output field. The password must match exactly or decryption will fail.
Yes! The tool uses AES-GCM 256-bit encryption, which is the same standard used by governments and military organizations worldwide. With PBKDF2 key derivation using 100,000 iterations, it provides strong protection against brute-force attacks. However, security depends on using a strong, unique password.
A strong password should be at least 16 characters long and include uppercase letters, lowercase letters, numbers, and special characters. Avoid dictionary words, personal information, or predictable patterns. Use our built-in password generator to create cryptographically secure random passwords.
No! All encryption and decryption operations are performed entirely in your browser using JavaScript. Your text, passwords, and encrypted data never leave your device or get transmitted to any server. This ensures complete privacy and security.
No. Due to the nature of strong encryption, if you lose the password, the encrypted data cannot be recovered. There is no password reset or recovery mechanism. Always store your encryption passwords securely and create backups of important data.
AES-GCM (Galois/Counter Mode) is recommended as it provides both encryption and authentication, protecting against tampering. AES-CBC (Cipher Block Chaining) is an older mode that only provides encryption. GCM is generally faster and more secure for modern applications.
