Fixing a https Cert in Windows

Ever need to reset a password in Bonobo Git Server ?

So, you've forgotten your password to bonobo git. Step 1: Get access to the sqlite file, probably called something like  Bonobo.Git.Server.db, sitting in the "wwwroot\Bonobo.Git.Server\App_Data" directory. Step 2: Using another tool, generate an md5 hash of your new desired password (as far as I know, sqlite does not have md5 capability) Step 3: Back in sqlite, using SQL, update the relevant user record, something like update User set Password = UPPER( 'thenewMD5hash') where Username = 'admin' ; Step 4: That's it, you are done, log in with your newly found password.

Insert the following code to the Modules section. On the left side there is a tree, expand until you find Modules. Then, if there is not a Module item under Modules, create one by right clicking on Modules. Or right click and choose Insert -> Module. Now, paste the text below in the main VBA window. Close the VBA IDE. Create a Rule that calls the script. Tools -> Rules and Alerts -> New Rule... In the first screen of the new rule wizard, choose "Check messages when they arrive". In the second, you could specify certain criteria that the message must match. Tip: Try "with specific words in the message header" and ...
