Aloaha PDF Signator

Aloaha PDF Signator

Authenticity and integrity of PDF documents are increasingly becoming more important. Contrary to general belief PDF files can easily be modified. Thus digital signatures become more and more important. PDF (Portable Document Format) is a common open format for digital documents.

With the Aloaha PDF Signator this widely used file format can also be securely used for official business communication such as electronic invoicing, submitting of tenders or digital signing of contracts.

The Aloaha PDF Signator can sign and timestamp any existing PDF Document. Aloaha does not require special prepared PDF documents or signature fields.

The digital signature of the PDF file will automatically be checked and indicated by the PDF viewer (Acrobat Reader). The customer needs not to install specific software for this checking process.

The Aloaha PDF Signator supports software certificates and qualified certificates on SmartCards/e-ID Cards. All CSP supported SmartCards are also supported by Aloaha. Some SmartCards are supported native. These cards do not require a CSP (Crypto Service Provider) installed

  • PDF Signator allows you sign and certify PDF documents without any need to purchase full Adobe Acrobat® or Adobe Document Server for Reader extensions®. This dramatically reduces the Total Cost of Ownership (TCO). Software Certificates and Smart Cards are supported.
  • Using PDF Signator you can now open, view and navigate PDF documents directly within PDF Signator. Thus allowing you to view and sign the document all from the same application. (freeware feature).

Such signatures can be verified even after the signer's certificate expires or is revoked.
