About Hash Functions
What are Hash Functions?
Hash functions are mathematical algorithms that convert input data of any size into a fixed-size string of characters. They're designed to be one-way functions, making it nearly impossible to reverse the process.
Hash Algorithm Comparison
| Algorithm | Output Size | Security | Common Uses |
|---|---|---|---|
| MD5 | 128 bits (32 hex) | Legacy | File checksums, non-security uses |
| SHA-1 | 160 bits (40 hex) | Deprecated | Git commits, legacy systems |
| SHA-256 | 256 bits (64 hex) | Secure | Passwords, certificates, blockchain |
Common Use Cases
- File Verification: Check if downloaded files are intact
- Password Storage: Store hashed passwords securely
- Data Integrity: Ensure data hasn't been tampered with
- Digital Signatures: Verify document authenticity
- Blockchain: Mining and transaction verification
