You can buy the PDF Sign&Seal support package from the website by following these steps:
Sometimes configuration files get corrupted by not closing application in standard way. This issue can be resolved by following the below given steps:
Create backup of "AppSettings.xml"
PDF Sign&Seal display location is defined in application data. Sometime by changing the resolution setting its displayed location values change to unreal values. This issue can be resolved by performing the following steps
PDF Sign&Seal during its installation, stores user configurations in Application Data folder. It is observed that on certain machines two Application data folder one with the name 'Application Data' and the other '%appdata%' is present. In such a scenario, PDF Sign&Seal installation, copies the user configurations '%appdata%' instead of Application data folder. This problem can easily be solved by performing the following steps:
PDF Sign&Seal and PDF Signer Server are two different Ascertia products.
PDF Signer Server is marketing term given to ADSS Server when supplied with PDF signing and/or PDF signature verification modules. PDF Signer Server brings advanced digital signature and time-stamping capability to PDF documents and forms using a server-side solution. In this case the signature is created on the server. This can be done in an automated way or on demand through a web services interface. ADSS Server also allows client-side signatures to be applied to PDFs through the use of the ADSS Go>Sign applet. This is an ideal solution when the signing keys are held locally by the user (on smartcard, USB token or in software). Using the Go>Sign applet within a web-browser has a real benefit to external workflows since no signing software is required to exist on end user systems.
PDF Sign&Seal is a standalone desktop application that makes it easy to use digital signatures, time-stamp and strong encryption on business documents. It is expected to be used with an organization and it has been carefully designed for use by busy managers that have ease of use as a priority. Using PDF Sign&Seal anyone can easily create, sign or protect a business documents.
Both applications work without any need to purchase Adobe® licenses.
Long-term signatures are advanced digital signatures which have time-stamp and signer certificate revocation status embedded within them. This information is added at the time of signing to prove the time of signing and the fact that the signer’s certificate was valid at signing time. Such signatures are valuable because they give people unequivocal proof that the contents of a data file existed at a point-in-time and that the contents have not changed since that time, regardless of any later change of signing certificate status or expiry. The PDF specifications fully support such long-term signatures and signatures produced by PDF Sign&Seal are thus fully compatible with Adobe® Reader.
Yes, a complete certificate chain is required in order to trust the timestamp token as a path is built up to the Root CA of the timestamp token. The intermediate CAs in the TSA certificate chain may either be present within the verifier’s Windows® certificate store or embedded directly within the time stamp token. The Root CA must exist within the Verifier’s Windows certificate store.
If certificate path building fails then ensure that the intermediate certificate(s) are present in your Windows® certificate store (they may or may not be embedded within the timestamp token – depending on which TSA authority created the token). You can access your browser’s certificate store from Internet Explorer > Internet Options > Tools > Content > Certificates > Intermediate Certification Authorities/Trusted Root Certification Authorities.
Yes, a complete chain is required in order to trust the signer certificate, since as part of trust checking a path is built to the relevant Root CA. The intermediate CAs in the signer certificate chain may be present within the signature itself but the Root CA must be pre-installed within the verifier’s Windows environment.
If certificate path building fails then ensure that the intermediate certificate(s) are present in your Windows® certificate store (they may or may not be embedded within the signature – depending on which application created the signature). You can access your browser’s certificate store from Internet Explorer > Internet Options > Content > Certificates > Intermediate Certification Authorities/Trusted Root Certification Authorities.
Yes PDF Sign&Seal supports PDF/A compliant signatures. Signature images used within signature appearances need to be non-transparent in order to be PDF/A compliant.
PDF Sign&Seal is designed to work on Microsoft® (32-bit and 64-bit) operating systems including:
PDF Sign&Seal requires the Microsoft .Net Framework 4.7 and onwards which should be pre-installed on your machine.
It is also possible to consider implementing the core functionality of PDF Sign&Seal on the following operating systems as part of a project: Linux, Solaris and Other UNIX based operating systems.
Yes, PDF Sign&Seal support digest authentication over an HTTP proxy, this can be configured from PDF Sign&Seal Preferences > Connection pane.
PDF Sign&Seal supports the following types of signatures:
PDF Sign&Seal supports SHA1 and SHA2 for hashing and RSA for signature algorithms. For PDF encryption it uses AES (128-Bit) and RC4 (128-Bit) algorithms. Both X.509 v1 and v3 digital certificates are supported. CRL (v1 and v2) and OCSP (RFC 2560) based certificate validation is also supported.
PDF Sign&Seal support PDF acroform files of version v1.3+ (i.e. form PDF files, portraits, landscapes, etc). Versions below this are supported but Reader does not handle visible signatures properly for these old versions, hence interoperability is affected.
There is no limitation on the PDF document size that can be accepted provided there is sufficient memory available. Typically if the system RAM is 1024MB, PDF Sign&Seal is capable of handling PDF documents of up to 10 MB.
PDF Sign&Seal supports the following revocation checking mechanism(s) in this order:
Yes, PDF Sign&Seal supports Tablet PCs. While designing a signature appearance it is possible to create your own dynamic hand-signature image using Tablet PC ink support. Also it is possible to write directly on an opened PDF document using Tablet PC ink.
PDF Sign&Seal is an inexpensive solution to digital sign PDF documents using flexible signature appearances. You can bulk process (sign, seal or sign&seal) many documents in one click. In addition to this, PDF Sign&Seal allows users to stamp, watermark, attach files, add sticky notes and fill forms very cost effectively.
If you have any technical queries regarding PDF Sign&Seal then email details of the question or issue to firstname.lastname@example.org or submit a support ticket to technical support from the support page on our website https://www.ascertia.com/fusion/index.php?/Tickets/Submit/RenderForm/15/ Remember to include the product logs, any screenshots and steps you performed to produce the issue.
PDF Sign&Seal is a multi-lingual product and new languages can be requested by emailing the details to email@example.com.
Yes, PDF Sign&Seal support attachments, watermarks and stamps.
Yes, PDF Sign&Seal allows you to view multiple documents. The process is simple, select all the desired documents, right click and choose “Open PDF Sign&Seal” option or open multiple documents from within the main application. Each document is shown in its own tab within the PDF Sign&Seal application.
Yes Adobe® Acrobat® and Adobe Acrobat Reader products verify digital signatures produced by PDF Sign&Seal.
The size of the signed file increases (i.e. in comparison of the original unsigned file) depending upon the size of the images placed within the signature appearance. For long-term signatures additional space is used to add the timestamp and the certificate chain validation information.
