🔐 What is AES Encryption?
AES (Advanced Encryption Standard) is a symmetric encryption
algorithm adopted by the U.S. government in 2001. It's used worldwide to
protect classified information and is the industry standard for data encryption.
- Symmetric: Same key encrypts and decrypts
- Block Cipher: Encrypts data in 128-bit blocks
- 256-bit Key: This tool uses AES-256 (strongest variant)
- CBC Mode: Cipher Block Chaining for enhanced security
⚙️ How This Tool Works
- Key Derivation: Your passphrase is strengthened using PBKDF2
with 1000 iterations and a random salt
- IV Generation: A random 128-bit Initialization Vector is
created for each encryption to ensure uniqueness
- Encryption: AES-256-CBC algorithm transforms your plaintext
into ciphertext
- Output: Results are Base64-encoded for easy sharing
🛡️ Security Best Practices
🔑
Use Strong Keys: 12+ characters with mixed case,
numbers, and symbols
🎲
Random is Better: Use the random key generator for
maximum security
📝
Save Your Keys: Store keys securely - you'll need
them to decrypt
🚫
Never Share Keys: Never send your key through the
same channel as encrypted data
🔄
New IV Each Time: The tool automatically creates a
new IV for each encryption
⚠️
Educational Use: This is a learning tool. For
production use, consult security professionals
