What are Cryptographic Hashes?
Cryptographic hash functions convert input data of any size into fixed-size strings (hashes). They're one-way functions - you can't reverse a hash to get the original data back.
Common Hash Algorithms
| Algorithm | Output Size | Security | Use Case |
|---|---|---|---|
| MD5 | 128-bit (32 hex) | ❌ Broken | Legacy, checksums only |
| SHA-1 | 160-bit (40 hex) | ⚠️ Deprecated | Git commits (legacy) |
| SHA-256 | 256-bit (64 hex) | ✅ Secure | Passwords, Bitcoin |
| SHA-512 | 512-bit (128 hex) | ✅ Secure | High-security applications |
Use Cases
🔒 Password Storage - Hash passwords before database storage
📁 File Integrity - Verify files haven't been corrupted
🔐 Digital Signatures - Create unique fingerprints for documents
⛓️ Blockchain - Bitcoin and cryptocurrency mining
🛡️ API Security - Generate request signatures
