老外的提问：
I‘m using Fiddler2 (or trying) to capture SSL traffic for a windows desktop gadget hitting an https web service. It used to work, and then it stopped a couple days ago, always with this error:
---------------------------
Unable to Generate Certificate
---------------------------
Creation of the interception certificate failed.
makecert.exe returned -1.
Results from C:\Program Files\Fiddler2\MakeCert.exe -ss my -n
"CN=DO_NOT_TRUST_FiddlerRoot, O=DO_NOT_TRUST, OU=Created by
http://www.fiddler2.com" -eku 1.3.6.1.5.5.7.3.1 -r -cy authority -a
sha1
Error: Can‘t create the key of the subject (‘JoeSoft‘)
Failed
-------------------------------------------
(I swiped the error from the google group for fiddler, although I just posted my own and it should be visible soon).
Has anyone else had this problem and solved it? Is Fiddler just broken?
找到一个比较实际的解决：
The simple fix for me was to install the Fiddler CertMaker--http://fiddler2.com/r/?fiddlercertmaker
【转】Fiddler https 证书问题
