This tool performs local Twofish encryption/decryption with 128/192/256-bit keys and multiple block modes for compatibility and security testing use cases.
Key Features
- Twofish with 128/192/256-bit keys
- CBC, ECB, CFB, and OFB modes
- Multiple input/output encodings and paddings
- Real-time key/IV length validation
Steps
- Choose encrypt/decrypt and key size.
- Configure mode, padding, and encoding formats.
- Enter key, IV, and input text.
- Run and copy the output.
Notes
- Valid IV is required for non-ECB modes.
- Parameter mismatch can cause decrypt failure or invalid output.
- For new systems, widely standardized algorithms (such as AES) are usually preferred.
