About SHA-256
What is SHA-256?
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 256-bit (32-byte) hash value. It's part of the SHA-2 family designed by the NSA and is widely used in security applications and protocols.
Features
- Generates 256-bit (64 hex character) hash
- Cryptographically secure (no known collisions)
- Deterministic and one-way
- Industry standard for security
- Used in Bitcoin and blockchain
- FIPS 180-4 compliant
