Cryptographic Hash
A persistent SHA-256 or similar checksum embedded or recorded with the document to prove the file hasn't changed since signing.
A Business HashDoc documents commercial terms while preserving integrity through a cryptographic hash and an auditable signing trail. It reduces disputes about later alterations and supports admissibility of the electronic record under ESIGN (15 U.S.C. §7001) and applicable state UETA provisions.
The Business HashDoc is commonly used by professionals across several commercial sectors where record integrity and electronic execution matter.
Typical signers are authorized representatives, contracting officers, or delegated signatories; ensure signatory authority is documented within corporate records before execution.

Mechanisms that flag any alteration after signing, such as incremental hashes or sealed PDF signatures, preventing silent edits.
