What is AES Encryption?
AES is the global standard for symmetric encryption, providing high-speed and secure data protection.
Core Value
- Extremely fast encryption/decryption
- Low resource consumption
- Strong security against attacks
- Global industry standard
Common Configurations
- 128 / 192 / 256 bit keys
- CBC / ECB / CTR modes
- Pkcs7 / ZeroPadding
Scenarios
- Local file encryption
- Database field encryption
- API data transmission security
- WiFi WPA2 security
Technical Features
- Symmetric encryption (same key for both)
- Block cipher algorithm
- Multiple operation modes supported
🚀 How to Use
- Select Mode: Choose 'Encrypt' to protect data or 'Decrypt' to restore it.
- Parameters: Enter the key (and IV if required) and select the corresponding mode and padding.
- Input: Paste the text or ciphertext, and the result will be generated in real-time.
💡 FAQ
What is the difference between ECB and CBC?
ECB is simple but less secure for repetitive data. CBC uses an IV to ensure different ciphertext for the same plaintext, providing better security.
How to choose key length?
128-bit is secure and efficient for most uses. 256-bit offers maximum security and is resistant to quantum computing threats.
