TEA/XTEA/XXTEA Online Encryption/Decryption

Online TEA/XTEA/XXTEA encryption/decryption tool, supporting CBC/ECB/CFB/OFB modes, widely used in embedded systems and game development

Security Notes

TEA/XTEA/XXTEA are mainly used for lightweight encryption in embedded systems and games. For applications requiring high security (e.g., banking, personal privacy), please use AES algorithm.

Documentation

This tool performs local encryption/decryption with TEA, XTEA, and XXTEA algorithms, including multiple modes and encoding formats.

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.
