Evidence to "v_Url_kkrbu11prwvcvrodib3znhgi3grjlljh"...how ?

[Sky]

Hello:
I'm having to build a userSettings provider to work on CE...

There's a detail of it that is really stumping me: generating the folder
name to store the user.settings in.

The folder that is created to store the user.config in is formed by the
following rule:

{ApplicationSettings}\
{first25charsOfEntryAssemblyName}
_
{EvidenceType}
_
{EvidenceHash}

The last two parts, come out, for example as the followinng string fragment:

"Url_kkrbu11prwvcvrodib3znhgi3grjlljh"

The question is...how? What algorythm is used to generate this? How did an
Evidence instance get to become the word "Url", and was it the
Evidence.HashCode (doubt it!) that was encrypted as
"kkrbu11prwvcvrodib3znhgi3grjlljh", and by what method?

Thank you very very very much for any help on figuring this one out.
