RSA Encryption I need to encrypt the body in restMessagev2

[Ayoub Ayed]

I need to encrypt the body of a request in RESTMessagev2 using RSA encryption.

Did you have any Idea about how to encrypted the body my code I try to do that is :

try {

    var requestId = "c20e3fde0c8916......";

    var requestNumber = "RITM0011......";

    var gr = new GlideRecord("sc_req_item");

    if (!gr.get(requestId)) {

        gs.error("Record not found for request ID: " + requestId);

    }

    var token = ".......................";

    var r = new sn_ws.RESTMessageV2('Apis', ' api');

    gs.info("Bearer " + token + " ,region " + region);

    r.setRequestHeader('Authorization', "Bearer " + token);

    var publicKey =

        "-----BEGIN PUBLIC KEY-----\n" +

        "MIICIjANBgkqhkiG9w0BAQEFAAOCAg8AMIICCgKCAgEAt8YpwXBWXWOJiOFIhpek\n" +

       "........."

        "-----END PUBLIC KEY-----";

    function rsaEncrypt(value) {

        return CryptoUtil.encrypt("RSA", value, publicKey);

    }

    // Encrypt the parameters

    r.setStringParameterNoEscape('Index', rsaEncrypt(requestNumber));

    r.setStringParameterNoEscape('type', rsaEncrypt(gr.variables.type.getDisplayValue()));

    r.setStringParameterNoEscape('...................', rsaEncrypt(gr.variables...........getDisplayValue()));

    r.setStringParameterNoEscape('..............', rsaEncrypt(gr.variables.................getDisplayValue()));

    r.setStringParameterNoEscape('................', rsaEncrypt(gr.variables.................getDisplayValue()));

    r.setStringParameterNoEscape('................', rsaEncrypt(gr.variables................getDisplayValue()));

    r.setStringParameterNoEscape('.............', rsaEncrypt(gr.variables.............getDisplayValue()));

    r.setStringParameterNoEscape('............', rsaEncrypt(gr.variables................getDisplayValue()));

    /

    var response = r.execute();

    var responseBody = JSON.parse(response.getBody());

    var status = response.getStatusCode();

    gs.info('System data status: ' + status + ' responseBody: ' + JSON.stringify(responseBody));

    if (status == 200) {

        gs.info(responseBody);

    } else {

        gs.info("API call did not return 200 status.");

    }

} catch (ex) {

    var message = JSON.stringify(ex);

    gs.error('Error: ' + message);

}





the response is :

*** Script: Error: {"message":"\"CryptoUtil\" is not defined.","fileName":"null.null.script","sourceName":"null.null.script","lineNumber":56,"name":"ReferenceError","stack":"\tat null.null.script:56 (rsaEncrypt)\n\tat null.null.script:60\n","rhinoException":{}}: no thrown error
