📖 What are Hashes?
A hash function converts any input into a fixed-size string of characters. The same input always produces the same hash, but you cannot reverse a hash back to the original input. Hashes are used for password storage, data integrity verification, and digital signatures.
🔒 Which to Use?
- SHA-256 — Best for most applications
- SHA-512 — Maximum security needs
- SHA-1 — Legacy systems only
- MD5 — Checksums only, never security
Common Use Cases
File Integrity
Verify downloaded files match the original by comparing hashes.
Password Storage
Store password hashes instead of plain text (use bcrypt/argon2 in production).
Data Deduplication
Identify duplicate files by comparing their hashes.
Digital Signatures
Hash documents before signing to ensure integrity.
