SHA-256 Security: Opportunities and Threats
SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash algorithm that belongs to the SHA-2 family of functions, developed by the National Institute of Standards and Technology (NIST) in the USA. SHA-256 generates a unique and fixed-size (256-bit) hash value from unlimited input. It provides a one-way process, which means that the original data cannot …
