Signing​ ​Tool​ ​API​ ​Anatomy​ ​v1.0.0

This document is intended for Portal / Developers / Websites to integrate the API into their Web application​ ​and​ ​Desktop​ ​Application.

This helps the user in making their entire signing work easy and secured

Standard​ ​Disclaimer

  • The​ ​specification​ ​can​ ​always​ ​change​ ​at​ ​last​ ​minute.
  • This​ ​is​ ​intended​ ​for​ ​selected​ ​people​ ​and​ ​is​ ​confidential.

Anatomy​ ​of​ ​Command

Request​ ​Command

This​ ​is​ ​​ ​root​ ​element​ ​it​ ​contains​ ​following​ ​elements All​ ​these​ ​element​s are​ ​sent​ ​in​ <command> <ts> <txn> <certificate><file> <pdf> <data>

<ts>

This​ ​is​ ​Time​ ​Stamping​ ​element,​ ​which​ ​the​ ​server​ ​would​ ​pass​ ​to​ ​the​ ​Signing​ ​Tool. (This ​​ is ​Optional ​Element) The signing tool would compare with the Client system Date and time and see the difference, if​ ​there​ ​is​ ​difference​ for​​ ​30​ ​seconds​ ​from​ ​ ​Server​ ​Date​ ​and​ ​Time​ ​it​ ​would​ ​not​ ​Sign. ​

<txn>

A​ ​unique​ ​ID​ ​could​ ​be​ ​passed​ ​with​ ​each​ ​Signing​ ​Request,​ ​it​ ​would​ ​help​ ​Web​ ​Application​ ​to​ ​get​ ​the response​ ​and​ ​map​ ​it​ ​to​ ​correct​ ​request. (This ​is ​Optional ​Element)

<certificate>

The​ ​application​ ​could​ ​also​ ​pass​ ​values​ ​to​ ​prompt​ ​signing​ ​tool​ ​to​ ​match​ ​for​ ​a​ ​certificate​ ​present in​ ​Browser​ ​Store​ ​and​ ​operations​ ​could​ ​be​ ​performed. (This ​is ​Optional ​Element)

  • If there are more than One Signature matching the criteria, then a Box showing all the matching​ ​signature​ ​would​ ​be​ ​shown,​ ​and​ user​ ​could​ ​select​ ​signature.
  • If only One Signature is found, then our application would only show the pop up for Password​ ​and​ ​it​ ​would​ ​automatically​ ​sign.
  • If​ ​no​ ​Parameters​ ​are​ ​sent​ ​then​ ​all​ ​allowed​ ​certificate​ ​would​ ​be​ ​shown.

The <certificate> ​can​ ​used​ ​with​ ​the​ ​following​ ​attributes​ ​with​ ​this​ ​element.

<file>

type​ ​​=​ ​​ The​ ​Type​ ​of​ ​Data​ ​which​ ​needs​ ​to​ ​used​ ​by​ ​the​ ​commands (This ​is ​Mandatory​ Element) Allowed​ ​variables​ ​​PDF​,​ ​​TXT​ ​​or​ ​​XML

inputfile​ ​​=​ ​​Unsigned file path (full), which need to be signed ( This is Optional if you passing <data> element

outputfile​ ​​=​ ​​ ​Signedfile copied here (optional)

<pdf>

This​ ​Element​ ​is​ ​used​ ​when​ ​<file> ​element​ ​is​ ​PDF (This ​is ​Optional ​Element)

  • This Element is is used when we would want to sign the PDF file in particular Page and in Particular​ ​Place.
  • In case no values are passed, the signing would happen in the file invisible form (No Physical​ ​footprint​ ​would​ ​left​ ​in​ ​file).
  • If the values are passed with <file> not equal to PDF the values present would not be affect the​ ​Signing​ ​process.
  • This​ ​element​ ​is​ ​used​ ​for​ ​Signing​ ​only.
