T4 Pdf Digital Signatures Aatl
Our digital signatures are automatically trusted by Adobe Acrobat Sign. Advanced and Qualified Signatures / Seals
Adobe Acrobat Sign
Digital Signatures not only confirm the identity of the signer but also hold legal validity in courts across different jurisdictions. In the realm of paper-based transactions, two significant issues arise: 1. The susceptibility of signatures to forgery 2. The potential for document content alteration after the application of ink signatures.
Advanced signatures or seals are provided by a Trusted Service Provider (TSP) and have identity vetting. Whereas, a qualified certificate must be issued by a Qualified Trust Service Provider (QTSP) and generated using a Qualified Signature Creation Device (QSCD), supported by the highest level of identity vetting in accordance with eIDAS regulations.

Revolutionize Contract Signing with Digital Signatures
Integrity – Efficiency – Security
In the era of digital transformation, where mundane paperwork is a thing of the past, prepare yourself for an extraordinary experience with our unparalleled online contract signing solution. This isn’t just about e-signing or electronic signatures; it’s about the power of digital signatures
Multiple Signing Modes
Allows e-signatures or digital signatures as per your regulatory or business needs.
Sign anytime, anywhere
Collaborate effortlessly with stakeholders across different locations and time zones. Empower your team and clients to sign documents from anywhere, on any device, and keep your business moving forward with speed and flexibility.
Multiple Workflows
Create and manage multiple workflows from a single dashboard with multiple documents (package) to process. Add multiple reviewers or signers in a workflow. Recipients can sign or approve as per their roles. Allow serial or parallel workflows.
Package Signing
Simplify multi documents processing by allowing multiple documents in a package with multiple signers or approvers.
Cross Platform, Diverse Deployments
Whether you choose Windows or Linux, our platform-independent solution seamlessly adapts to your environment, including on-premise private or public cloud, VMs, and physical machines. Enjoy the flexibility of deployment options that suit your specific needs.
Standard & Compliant
Supports industry regulations, including the eIDAS, ESIGN Act, UETA, HIPAA and FDA 21 CFR Part 11, allowing you to confidently meet legal requirements and maintain the highest standards of data integrity and security
Configurable Signature Appearance
The T4 Signing Server stands as a tried-and-true, standards-based solution suitable for on-premise deployment in enterprise environments or seamless integration within managed cloud services. Its exceptional capabilities cater to the most rigorous demands, ensuring superior throughput and unwavering availability.
Timestamping
Timestamps are easier to verify when they’re associated with a timestamp authority’s trusted certificate. Including a timestamp helps to prove that the document wasn’t changed after you had signed it and it reduces the chances of an invalid signature.
Invoice Signing
Invoice Signing – PDF Signer Server allows organizations to digitally sign and process large numbers of invoices. EU VAT Directive requires that: “Invoices sent by electronic means shall be accepted by Member States provided that the authenticity of the origin and integrity of the contents are guaranteed”.
Bulk %22Automated%22 Signing
With this product you can quickly sign multiple PDF files (bulk sign) by selecting input and output directory. This is ideal for bulk signing of a large number of corporate documents rather than signing each one individually.
Long-Term Validation
PDF Signer Server supports advanced digital signatures which include embedded RFC 3161 compliant secure timestamps. Such signatures can be verified even after the signer’s certificate expires or is revoked.
PKI Interoperability
PDF Signer Server is completely PKI neutral and will work with PKI components from any vendor (this includes CAs, certificates, CRLs, smartcards, etc.).
Timestamp Server Authority (TSA)
Accuracy, Integrity, Trustworthiness
Proving time is important in high valued transactions and critical for businesses creating digital signatures for long-term perseverance. Without cryptographic timestamps, digital signatures can’t be trusted as they cannot be accepted in long term. A Timestamp server (also called as Timestamp Authority or TSA as short) provides proof of data existence at a particular point in time using cryptography.
A Timestamp Authority acts as a pivotal role ensuring all of the cryptographic objects identified during digital signature creation remains valid be it digital certificates, CRL or OCSP. This is done by embedding RFC 3161 based cryptographic timestamps inside business documents or transactions. Digital signature standards from ETSI or IETF now require cryptographic timestamps to be embedded ensuring long term storage and archiving.
Core Features
Features You Get From Our Tsa
Complexity creates confusion and bound to create operator mistakes. With developer and admin friendly interfaces, TSA can be deployed, integrated & tested in far less time what others offer.
Support any HSM & CAs
Quickly integrates with your existing HSMs over PKCS#11. Some of these are: – Entrust nShield – Thales Luna & Protect Server – Utimaco Cryptoserver – Microsoft Azure Key Vault – AWS HSM etc. Environments which doesn’t require HSMs, can still use software based cryptographic keystores. Timestamp certificates can be certified with your existing CAs for quick import and usage.
Proactive Alerts & Troubleshooting
In situations where timestamp server is not working as it should, Khatim timestamp server proactively notifies administrators to take immediate action. For traceability, all issues are recorded which can be pushed securely to your central logging systems. Some of these are: – Splunk – Grafana – Greylog – LogRhythm etc.
Multiple Workflows
Create and manage multiple workflows from a single dashboard with multiple documents (package) to process. Add multiple reviewers or signers in a workflow. Recipients can sign or approve as per their roles. Allow serial or parallel workflows.
NTP Aware
Timestamp server can be configured to use: – System time (synched with a trusted time source) – NTP (over RFC-1305 or SNTP RFC-2030) – Checks local clock time drift with NTP
