This article describes how to convert a certificate that is received from the Certificate Authority (CA) in PKCS #7 format to PEM format.
This is an alternative method of converting a PKCS #7 Certificates to PEM format, rather than using Open SSL, which sometimes might not work correctly.
Certificate is in the PKCS #7 [Crypto Graphic message syntax standard] format, and the file extension is .p7b.

1. Double-click on the certificate to open it



2. Expand the path to reveal the certificate, then double-click on it



3. Select the Details tab

4. Click "Copy to File..."



5. Click "Next" in the Certificate Export Wizard window

6. Select the "Base-64 encoded x.509 (.CER) option". This converts the certificate to PEM format.



7. Click "Next"

8. Click "Browse" and select a location to store the converted PEM



9. Click "Next"

10. Click "Finish"



After converting the certificate to PEM format, the certificate has an extension .cer.
