SHA-256

SHA-256 is a cryptographic hash function from the SHA-2 family that generates a 256-bit fingerprint (hash) of any input data.

Full Definition

SHA-256 is considered a secure cryptographic standard approved by NIST and used in TLS certificates, digital signatures, blockchain and secure password storage. In the context of electronic signing, SHA-256 is used to create a document 'fingerprint' that is signed — ensuring that even a minimal change to the document after signing will be detectable.
