Protect PDFs, contracts, and corporate documents with tamper-proof cryptographic signatures.
A digital credential issued by a trusted Certificate Authority that guarantees document authenticity:
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.
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.
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.
Ensure bulletproof security and build trust across all digital contracts and sensitive files:
Uses robust 2048-bit encryption, making signed files virtually unbreakable with current technology and secure from alterations.
Your private key is securely stored in a FIPS-compliant iKey USB token with two-factor PIN authentication for maximum physical protection.
Validated certificates prove your organization's legitimacy, ensuring documents are signed by an authentic authorized representative.
Works seamlessly across Adobe Acrobat, Microsoft Office (Word, Excel), and open-source LibreOffice on desktop and mobile.
A transparent breakdown of public key infrastructure in digital document signing:
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.
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.
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.

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.
