MD5 encryption description:
- Difference between 16-bit and 32-bit: 16-bit is the middle part of 32-bit, slightly less secure but faster to calculate
- Irreversibility: MD5 is a one-way encryption algorithm that cannot be decrypted to restore the original text
- Collision: Theoretically, there may be cases where different content produces the same MD5 value
- Security advice: It is recommended to use with salt in scenarios such as password storage
Application scenarios:
- Password encryption: Used for encrypted storage of user passwords
- File verification: Verify the integrity of downloaded files
- Data signature: Ensure consistency of data transmission
- Version control: Detect whether files have been modified
- Cache processing: Generate unique identifiers for files
Security tips:
- MD5 is not suitable for storing important password data, it is recommended to use more secure encryption algorithms
- In password encryption scenarios, it is recommended to use salt and multiple encryption
- When verifying files, it is recommended to use other verification algorithms (such as SHA-1) at the same time to increase reliability
