Implementation of SSL ON SQL SERVER DEFAULT INSTANCE
Ok this is what i've referenced thesqldude.com/tag/makecert for creating self signed certificate. JIST :

1) MAKECERT tool used for preparing certificate with command mentioned in link above – 

FYR : 
     makecert -r -pe -n "CN=cs020.classic.classicinformatics.net" -b 01/01/2000 -e 01/01/2036 -eku 1.3.6.1.5.5.7.3.1 -ss my -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12 

Where "cs020.classic.classicinformatics.net" is my system FQDN. 

2) Then open mmc and added console to view certificate, And it was automatically restored in the certificate store under "personal" 
3)Then opened SCM and view properties of SQL SERVER protocal. 

FYI: My system hostname was "cs020" and its in domain "classic.classicinformatics.com". 
     If it was in workgroup then creating certifcate with "CN=cs020" would have worked, 
     but i check my fullcomputer name and it was stating something else 
     i.e. "cs020.classic.classicinformatics.net" , so there was it, i've used the above command and got my results.
