This tool performs local Rijndael encryption/decryption with variable block and key sizes, useful for compatibility scenarios beyond standard AES settings.
Key Features
- 128/192/256-bit block size support
- 128/192/256-bit key size support
- CBC, ECB, CFB, OFB, CTR, and RAW modes
- Multiple input/output formats and padding options
Steps
- Select encrypt or decrypt.
- Configure block size, key size, mode, and padding.
- Provide key and IV (IV depends on selected mode).
- Process data and copy the result.
Notes
- AES is a standardized subset of Rijndael with fixed 128-bit block size.
- Non-standard block sizes require matching support on both sides.
- Keep all parameters identical for reproducible results.
