ESIGN Act & eIDAS Compliant E-Signatures
Every signature on eSignHub is legally binding under the US ESIGN Act and EU eIDAS Regulation. Consent recording, SHA-256 document hashing, tamper-proof audit trails, and auto-generated completion certificates - all built in.
Complete Compliance Built Into Every Signature
eSignHub doesn't just capture signatures — it builds a complete legal evidence package around every signing ceremony. eSignHub doesn't just capture signatures - it builds a complete legal evidence package around every signing ceremony.
Signer Consent Recording
Every signer explicitly consents to signing electronically. The consent text, timestamp, and acknowledgment are permanently recorded in the signature record - satisfying ESIGN Act Section 7001(c) and eIDAS Article 25 requirements.
SHA-256 Document Hashing
At the moment of signing, eSignHub computes a SHA-256 cryptographic hash of the document. This 256-bit fingerprint provides mathematical proof that the document has not been altered since signing - ensuring document integrity as required by both ESIGN and eIDAS.
Tamper-Proof Audit Trail
Every audit log entry is hash-chained to the previous entry, creating a blockchain-like tamper-proof chain. If any entry is modified or deleted, the chain breaks - providing irrefutable evidence of the complete signing history.
Completion Certificates
When all signers have signed, eSignHub automatically generates a professional PDF certificate containing every signer's name, email, timestamp, IP address, verification code, and the document's SHA-256 hash. A single document that proves the entire signing ceremony.
Cross-Border Legal Validity
eSignHub signatures are valid in the United States (ESIGN Act, UETA), the European Union (eIDAS Regulation), the United Kingdom (UK eIDAS), Canada (PIPEDA), Australia (Electronic Transactions Act), and 50+ additional jurisdictions that recognise electronic signatures.
Signer Identification & Intent
Each signature captures the signer's name, email, IP address, user agent, timestamp, and a unique verification code. Combined with the consent record and document hash, this establishes clear signer identity and intent to sign.
Real-Time Verification
Every signature includes a unique 16-character verification code. Anyone can verify a signature's authenticity by entering this code in eSignHub, confirming the signer, timestamp, and document integrity without needing the original parties.
Court-Ready Evidence Package
The combination of consent recording, document hashing, hash-chained audit trails, IP logging, and completion certificates creates a comprehensive evidence package that meets the evidentiary requirements of courts in the US, EU, UK, and beyond.
Regulation-by-Regulation Compliance
Here's exactly how eSignHub meets the requirements of each major e-signature regulation.
US ESIGN Act (15 U.S.C. Sections 7001-7006)
Fully compliantFederal law granting e-signatures legal equivalence to handwritten signatures in interstate and international commerce.
- Intent to sign - Captured through explicit consent and signature action
- Consent to do business electronically - Recorded with timestamp
- Association of signature with the record - Linked via document ID, field ID, and PDF hash
- Record retention - Signatures, consent, and audit logs stored securely
EU eIDAS Regulation (No 910/2014)
SES compliant (Simple Electronic Signature)EU regulation establishing a legal framework for electronic identification and trust services across all member states.
- Article 25(1) - Electronic signature not denied legal effect solely on grounds it is electronic
- Article 3(10) - Signature data uniquely linked to signatory (email + verification code + IP)
- Document integrity - SHA-256 hashing detects any post-signature modification
- Audit trail - Hash-chained log provides tamper-proof evidence chain
UK Electronic Communications Act 2000 + UK eIDAS
Fully compliantPost-Brexit UK retains eIDAS standards via the Electronic Identification and Trust Services for Electronic Transactions (Amendment etc.) (EU Exit) Regulations 2019.
- Electronic signatures admissible as evidence in legal proceedings
- Signer identification via email, IP address, and verification code
- Document integrity verified via SHA-256 hash comparison
- Audit trail demonstrating complete signing ceremony
UETA (Uniform Electronic Transactions Act)
Fully compliantUS state-level law adopted by 49 states, providing the legal framework for electronic records and signatures within state commerce.
- Attribution - Signature linked to signer via consent, email, IP, and verification code
- Effect of electronic record - Same legal effect as paper record

How Compliance Works in eSignHub
Document Upload or Template
Upload your document or generate one from 150+ templates. eSignHub prepares it for signing with compliance fields.
Signer Consent
Each signer sees a clear consent notice and explicitly agrees to sign electronically. The consent text, timestamp, and IP are recorded.
Document Hashing
At the moment each signature is applied, eSignHub computes a SHA-256 hash of the document - creating a cryptographic fingerprint of the exact state of the document.
Signature & Audit Trail
The signature, consent record, document hash, signer details, IP address, and verification code are logged in the tamper-proof hash-chained audit trail.
Completion Certificate
When all signers have signed, eSignHub generates a PDF completion certificate summarising every signature, timestamp, IP, verification code, and the final document hash.
Auto-Generated Completion Certificates
When all signers have signed, eSignHub automatically generates a comprehensive PDF certificate. No manual work required - the certificate is created instantly and linked to the document.
