Need Help with Signing User ID Using Private Key in ServiceNow

[DEV 1]

Title: Need Help with Signing User ID Using Private Key in ServiceNow

Description:

We are attempting to make a REST call to MuleSoft from ServiceNow, and we need to pass the signed User ID in the headers to MuleSoft. To achieve this, we have a certificate and private key in ServiceNow, and we aim to sign the User ID using the private key in ServiceNow scripts.

Here's what we've tried so far:

javascript:

var ce = new CertificateEncryption;

var signature = ce.sign("recordID", "alias", "password", "SHA1withRSA", "sign this data");

Here's our current setup in the ServiceNow platform:

• We have uploaded the server certificate .PEM file in the Certificates table.

Below are the parameters we are using for the method:

• record ID: sys ID of the certificate we uploaded.
• alias: N/A
• password: N/A
• SHA1withRSA: SHA256withRSA
• sign this data: User ID to sign

However, we are encountering the issue of getting a null signature.

We are unsure about the variables alias and password to pass to the method.

Any assistance or guidance on resolving this issue would be greatly appreciated.

Thank you!
