About SHA-256
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a fixed-size 256-bit (32-byte) hash value from any input data.
Key properties of SHA-256:
- Deterministic - The same input will always produce the same output
- Fixed Length - All outputs are the same length (64 hexadecimal characters)
- One-way Function - It is computationally infeasible to reverse the hash to find the original input
- Collision Resistant - It is extremely unlikely for two different inputs to produce the same hash
Common uses include data integrity verification, password storage, digital signatures, and blockchain technology.
