This tool performs local RSA encryption, decryption, signing, verification, and key-pair generation for public-key testing and learning workflows.
Key Features
- Key pair generation (1024/2048/4096-bit)
- RSA encryption and decryption
- Digital signing and signature verification
- Key import, export, and copy actions
Steps
- Choose operation tab (encrypt/decrypt/sign/verify/key generation).
- Configure key size, padding, and hash algorithm.
- Import or generate public/private keys.
- Input data, run operation, and copy output.
Notes
- Encrypt with public key and decrypt with private key.
- Sign with private key and verify with public key.
- Prefer 2048-bit or larger key sizes in practice.
