Document Hash
A fixed-length cryptographic fingerprint of a document's contents. If any byte of the document changes, the hash changes completely. Used to detect tampering.
Document hashing is the foundation of tamper detection in e-signatures. The process works in three steps: hash the document content to produce a fingerprint, store the hash in the signing certificate, and later re-hash the document to verify it matches.
Signbee uses SHA-256 hashing, which produces a 64-character hexadecimal fingerprint. The probability of two different documents producing the same hash is astronomically low.
