DIGITAL INTEGRITY

What is a Document Signing Certificate?

A digital credential issued by a trusted Certificate Authority that guarantees document authenticity:

CRYPTOGRAPHIC SEAL

Tamper-Proof Digital Signatures

Binds your verified identity to your electronic signature using 2048-bit RSA encryption. If any modification occurs after signing, the digital signature immediately invalidates, alerting all recipients to tampering.

• Encryption: 2048-bit asymmetric PKI • Tamper Alert: Instant invalidation on change • Non-repudiation: Proof of author and origin • Formats: PDF, DOCX, XLSX, ODT
ADOBE AATL CERTIFIED

Adobe® Acrobat Document Integrity

Leverages Adobe's Certified Document Services (CDS) and Adobe Approved Trust List (AATL). When opening the document in Adobe Acrobat Reader or DC, a green ribbon indicates the signature is authentic and verified.

• Green Checkmark: Built-in Adobe trust • Zero Configuration: Works out of the box • Corporate Trust: Recognized worldwide • Compatibility: Desktop and mobile PDF
LEGAL COMPLIANCE

Globally Legally Recognized

Digitally signed documents carry the same legal standing as handwritten ink signatures under the U.S. Federal ESIGN Act, UETA, and European Union eIDAS standards for electronic transactions.

• US Standard: ESIGN Act & UETA compliant • European Standard: eIDAS compliant • Audit Trail: Embedded cryptographic timestamp • Identity: Organization Validated (OV)

STEP-BY-STEP PROCESS

How Document Signing Certificates Work

A transparent breakdown of public key infrastructure in digital document signing:

VALIDATION & TOKEN

1. Identity Verification & Token Delivery

The Certificate Authority verifies the identity of the requester through official business registries. Once vetted, the CA provisions and ships a secure iKey USB hardware crypto token holding the private key.

• Vetting: Official organization & contact verification • Delivery: Shipped directly to verified business address • Security: Private key cannot be exported from hardware
SIGN & VALIDATE

2. Digital Signature Creation & Validation

Connect your USB token, enter your PIN, and apply your signature in Adobe Acrobat or Microsoft Office. The recipient's software decrypts the signature using your public key, establishing authenticity and verifying no tampering occurred.

• Signature Creation: Unique cryptographic hash created • Signature Validation: Automatic recipient trust verification • Tamper Alert: Altered files immediately trigger invalid flags
FAQ

Frequently Asked Questions

Common questions about this certificate type, validation standards, and deployment.

A document signing certificate is a digital credential issued by a trusted Certificate Authority (CA) that binds your verified identity to your digital signature, ensuring the authenticity, integrity, and legal compliance of electronic documents.

Yes. Document signing certificates comply with global standards like the U.S. Federal ESIGN Act, UETA, and the European Union eIDAS regulation, giving digital signatures the same legal weight as traditional pen-and-ink signatures.

To ensure that your private key cannot be exported, copied, or stolen by malware. The iKey USB token provides physical two-factor authentication, requiring both the physical device and a personal PIN to sign.

Yes. Document signing certificates are natively supported by Adobe Acrobat Reader/DC (via AATL), Microsoft Word, Excel, and open-source suites like LibreOffice.

Any modification made to the document after signing invalidates the cryptographic hash. Adobe Acrobat and other readers will immediately display a warning indicating that the document was modified and the signature is invalid.
