This tool performs local encryption/decryption with TEA, XTEA, and XXTEA algorithms, including multiple modes and encoding formats.
TEA/XTEA/XXTEA are mainly used for lightweight encryption in embedded systems and games. For applications requiring high security, such as banking or personal privacy, use AES instead.
Key Features
- TEA, XTEA, and XXTEA support
- CBC, ECB, CFB, OFB, and RAW modes (algorithm-dependent)
- Multiple input/output encodings
- Key and IV validation hints
Steps
- Choose encrypt/decrypt and algorithm type.
- Configure mode, padding, and formats.
- Enter key, IV, and input text.
- Process and copy output.
Notes
- TEA-family implementations vary; keep parameters strictly consistent across systems.
- Confirm implementation constraints when combining XXTEA with block-style modes.
- Prefer modern ciphers for security-critical production usage.
