    .PARAMETER SM_API_KEY
        The DigiCert API Key
         
    .PARAMETER SM_CLIENT_CERT_FILE
        The DigiCert certificate local path (p12)
         
    .PARAMETER SM_CLIENT_CERT_FILE_URL
        The DigiCert certificate URL (p12)
         
    .PARAMETER SM_CLIENT_CERT_PASSWORD
        The DigiCert certificate password
         
    .PARAMETER SM_CODE_SIGNING_CERT_SHA1_HASH
        The DigiCert certificate thumbprint(fingerprint)
         
    .PARAMETER FILE
        A file to sign
         
    .EXAMPLE
        PS C:\> Invoke-FSCPSDigiCertSignFile -SM_API_KEY "$codeSignDigiCertAPISecretName" `
        -SM_CLIENT_CERT_FILE_URL "$codeSignDigiCertUrlSecretName" `
        -SM_CLIENT_CERT_PASSWORD $(ConvertTo-SecureString $codeSignDigiCertPasswordSecretName -AsPlainText -Force) `
        -SM_CODE_SIGNING_CERT_SHA1_HASH "$codeSignDigiCertHashSecretName" `
        -FILE "$filePath"
         
        This will sign the target file with the DigiCert certificate
