Convert PFX Certificate to Base64 String

When working on Azure DevOps test plans, oftentimes you’d have to secure the communication between the resources using certificates.

For example, when establishing a secure connection between your VSTS build server and the Service Fabric cluster on Azure, you’ll have to give the Base64 encoded version of the pfx certificate that you’ve used to secure the service fabric cluster.

That way, your build server will be able to securely connect to the cluster to deploy packages or other artifacts.

Converting the pfx certificate to the Base64 encoded string is easy using Powershell.

1$fileContentBytes = get-content 'C:\Techfabric\TFProcess\Articles\convert\test-cert.pfx' -Encoding Byte
2[System.Convert]::ToBase64String($fileContentBytes) | Out-File 'pfx-encoded-bytes.txt'

The text file with the necessary bytes will be created in the same folder where the script is run.

Enjoy!
