What is SHA-256?Activity
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a unique 256-bit (32-byte) hash for any input, displayed as 64 hexadecimal characters.
Key Properties
Deterministic: Same input always produces the same hash
Fixed Output: Always 64 hex characters (256 bits)
Avalanche Effect: Small input changes create completely different hashes
One-Way: Computationally infeasible to reverse
Common
