Why AuthProof
Built for trust at scale

Cryptographic Proof of Authenticity
Every document is SHA256 hashed and RSA-SHA256 signed at upload - creating immutable, legally defensible evidence of origin and authorship.
Full Audit Trail
Complete chain-of-custody from upload to signed PDF. Every signature, key usage, and provenance record is logged, reportable, and independently verifiable.
Enterprise-Grade Security
