Converting Certificate to Base64 String

If you want to use a certificate to access an Azure AD application, you must provide the certificate as a Base64 string. To obtain a Base64 string, perform the following steps:

Get the certificate content from a PFX file.
Convert the certificate to a Base64 string.

To do this, you can use the following PowerShell cmdlets:

$pfx_cert = get-content '<path_to_cert>' -Encoding Byte

[System.Convert]::ToBase64String($pfx_cert) | Out-File '<path_to_file>'

where:

<path_to_cert> — path to the PFX file that you want to convert to a Base64 string.
<path_to_file> — path to a file that that will contain the resulting Base64 string. You will be able to copy the Base64 string from the file and provide the string in the body of a request to Veeam Backup for Microsoft 365 REST API.

For example:

$pfx_cert = get-content 'C:\cert.pfx' -Encoding Byte

[System.Convert]::ToBase64String($pfx_cert) | Out-File 'C:\base64.txt'
