Open ES3 File

The ES3 file is a document created by e-Szigno. The Hungarian-sourced e-Szigno signature creation application can create secure documents, electronic files, and signature certificates, which can encapsulate multiple signatures and can also store the corresponding metadata, making them particularly useful for supporting document flows work based on electronic signatures.

With a qualified electronic signature in a file with an .ES3 extension, a document with full evidential value equivalent to a handwritten signature can be created.

Electronic signature management offers a number of advantages over paper-based procedures. The software which generates the .ES3 extension, provides a complete set of tools to digitize verifiable business processes through signatures.
