Create a wild card certificate for Dynamics CRM

There are two ways

• MakeCertificate
• Powershell

 MakeCertificate

• Open command prompt
• Go to makecert.exe directory cd C:\Program Files (x86)\Windows Kits\8.1\bin\x64(check the path were your makecert.exe file is present)
•  Make your certificate

makecert.exe -r -pe -n "CN=*.contoso.com" -b 01/01/2010 -e 01/01/2050 -eku 1.3.6.1.5.5.7.3.1 -ss my -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12

(change the name contoso with your domain name. To check the domain name open Server Manager→ Local Server→ Domain)

Power Shell

• From windows server 2012 R2 makecert was depreciated and we have to use power shell
• Step:1 Download the ps1 file in the link https://gallery.technet.microsoft.com/scriptcenter/Self-signed-certificate-5920a7c6#content
• Step:2 Copy the download file and extract it into another folder C:\Test\
• Step:3 Open the power shell as administrator mode and then

PS C:\Test> . .\New-SelfSignedCertificateEx

PS C:\Test> New-SelfSignedCertificateEx -Subject "CN=*.minsa.org" -EKU "Server Authentication" -KeyUsage 0xa0 -StoreLocation "LocalMachine"  -ProviderName "Microsoft Strong Cryptographic Provider" -Exportable
