this is a common issue.

You can google all about it with

appdata roaming microsoft crypto rsa s-1-5-21

You shouldn't bother about it ;-)

Cheers and welcome here,

Hello

When signing PDF at present, the file can be made following folder in quantities, and I'm examining what this is.

Every time I sign PDF, this file is made, so I'd like to eliminate whether it outputs in a different folder.

May I eliminate this file or move?

C:\Users\UserName\AppData\Roaming\Microsoft\Crypto\RSA\S-1-5-21-・・・

A program will be the following.

(It's being made by VisualStudio 2008 C++.)
