[ease-dev] Sign and Verify Script

[Varun Raval <vraval48@xxxxxxxxx>]

Hi,

This week I worked on following things:

Sequence of dialog box to perform signature. Patch is updated to perform signature by self choosing appropriate provider to perform signature, to choose type of keystore by itself, to remember latest keystore used, and to remember user passwords of keystore and private key using Secure Preferences.

Gerrit change: https://git.eclipse.org/r/#/c/76997/ Status: open 

Added support of decorators in tree viewer of Script Explorer. Here, decorators will be used to tell signer whether signature needs to be modified or not.

Gerrit change: https://git.eclipse.org/r/#/c/78073/ Status: merged

While dealing with decorator, we need to perform signature check. These signatures are stored temporarily to state location so that user can't access signature directly. So, in this case, since data file and signature file are at different locations, support was required in existing VerifySignature class. For this, two new methods were added in VerifySignature class.

Gerrit change: https://git.eclipse.org/r/#/c/78068/ Status: merged

For decorators, certificate sign will be shown if signature is present and valid, and broken certificate sign will be shown if signature is invalid and needs to be updated. This decorator will be shown only in Script Explorer view and on IScript instances.

I started writing documentation for Sign and Verify classes.

Gerrit change: https://git.eclipse.org/r/#/c/78227/ Status: open

To verify signature before execution of remote scripts, I wrote an implementation of VerfySignature class, using which by calling a single method, we can decide whether to execute that script or not.
