Encrypt/Decrypt
AES/DES symmetric encryption and RSA asymmetric encryption
📖 Encryption/Decryption Tool Guide
Introduction
The Encryption/Decryption tool supports AES, DES symmetric encryption and RSA asymmetric encryption. All operations run in your browser — data never leaves your machine.
Features
- AES: Symmetric encryption with auto key generation
- DES: Classic symmetric encryption algorithm
- RSA: Public/private key encryption with key pair generation
- RSA Sign/Verify: Digital signatures for data authenticity
- 100% client-side: No data uploaded to servers
How to Use
- Select encryption type (AES, DES, or RSA)
- Symmetric: Enter/generate a key, choose encrypt/decrypt mode
- RSA: Generate key pair, encrypt with public key, decrypt with private
- View and copy results
Example
AES: "Hello World" + key "MySecretKey123" → encrypted Base64
RSA: Generate 2048-bit keys → encrypt with public → decrypt with private
RSA Sign: Private key sign → public key verify
Use Cases
- Encrypting sensitive config files locally
- Secure key exchange with RSA public-key encryption
- Verifying software package integrity with signatures
- Learning cryptography concepts
