Description of Hash Encryption Tool

This tool provides a standard cryptographic hash algorithm for generating unique fingerprints of data. All calculation results are are irreversible， Suitable for secure handling of sensitive information.

Supported algorithm types

• MD5 - 128-bit hashes, commonly used for file integrity checks.
• SHA series：
  • SHA1 (160 bits)
  • SHA256/SHA512 (higher security)
• HMAC algorithm - Hash message authentication code with key, to enhance the anti-tampering ability

Typical Application Scenarios

- User password encryption storage
- API interface request signature verification
- Software download package integrity checking
- Sensitive database information desensitization

Precautions for use

1. For password storage, it is recommended to combine the Randomized salt value Enhanced security
2. SHA256/SHA512 has stronger collision resistance than MD5.
3. Different input content (including case differences) will generate completely different hash values
