What Is Cryptographic Hashing?
A cryptographic hash function takes an input of any size and produces a fixed-size string of characters. Even a tiny change in the input produces a completely different hash — this property is called the avalanche effect.
MD5 vs SHA-256
- MD5 — fast, 128-bit. Good for checksums and file integrity. Not suitable for password storage.
- SHA-256 — industry standard, 256-bit. Used in Bitcoin, SSL certificates, and secure systems.
Common Uses
- File integrity verification
- Password hashing (use SHA-256+)
- Digital signatures
- Blockchain & cryptocurrency
- API request signing
