Codeunit 6227 "Signed XML Mgt."

(0) ShareShare
ReportReport
Posted on by Community Member Microsoft Employee

We are trying to implement XmlDocument signing on Business Central.

If we understand the code correctly, we're supposed to import certificates into isolated storage, which we did.

And then we think we're supposed to use SignXmlText function from codeunit 6227.

[External] SignXmlText(XmlText : Text;PrivateKey : Text) : Text

However there does not seem to be any way to get access to the privatekey.

By looking at the code this is supposed to be hex encoded binary blob with the actual private key data.

Are there any samples / documentation where we could see how we're supposed to do this?

Docker image: bcinsider.azurecr.io/bcsandbox-master

Application version: 14.0.26992.0

Platform version: 14.0.26873.0

    Codeunit 6227 "Signed XML Mgt."
    I got (what I think is a key) using the code:
     
    [Ok := ]  IsolatedStorage.Get(Key: String, [DataScope: DataScope], var Value: Text)
     
    It looks like: (11kb long)

    ...PU/B+DBBTUPQ0mM1HU9n2dZrHVLrRR6DP1lwIDAYag
     
    When I parse this to Cod6227 SignedXMLMgt.SignXmlText(), I got the error:
     
    A call to System.Security.Cryptography.RSACryptoServiceProvider.ImportCspBlob failed with this message: Bad Version of provider.
    The version I am using is BC14.

    He probably thinks about table 1262 "Isolated Certificate" not "Isolated storage"?

    This can be done through UI.

    How is your code for importing the certificate key into the Isolated Storage?

    You can read a key saved in the Isolated Storage by using:

    [Ok := ]  IsolatedStorage.Get(Key: String, [DataScope: DataScope], var Value: Text)

    With this method, the key you read is associated to the Value text variable.
