Questions
Where is SHA-256 used?
Widely: TLS certificate signatures, Bitcoin proof of work, package manager integrity checks, JWT HS256 signing (via HMAC), and file checksums. It is the sensible default when you need a general-purpose cryptographic digest.
Can a SHA-256 hash be reversed?
Not by inverting the function. However, if the input is low-entropy such as a common password or a short string, an attacker can simply hash candidate inputs until one matches. That is why password storage requires a salted, slow hash rather than a bare digest.
