Hi all,

Now I have different scenario I have mono running as a custom user
XYZ...however I am getting exception that mono can't write keypairs  to
follow in path
/root/.config/.mono/keypairs


Why it's trying to write key's to Root's path......

I am using nginx+fastcgimono ...


And this issue is very random I got 3/10 times...

Please help urgent

HI All ,

While calling ProtectedData.Protect(Encoding.Unicode.GetBytes("XXXXXXXXXXXXXXX"),

I am getting following error ....i am running my application under
fast_cgi_mono+nginx and running as non root user..

And following error is coming randomly not always.

I don't want to run my application as root user for Security reasons
.please advice
