    I am trying to decode base64 string into GUID. Is there any library I can use to convert it into guid ?

    For example:
    Base64 String = “qcx4JyAvkUi2HolTPX+q5A==” convert it into GUID = “2778cca9-2f20-4891-b61e-89533d7faae4” under IDM transforamtion script.

    You can call the org.forgerock.util.encode.Base64.decode() method directly within you transform script in order to decode the Base64 encoded String. Note that Base64.decode() returns byte[] and therefore if you require a String you will need to do something along the lines of the following:

    String.fromCharCode.apply(String, org.forgerock.util.encode.Base64.decode('Q2xlYXIgVGV4dCBTdHJpbmc='));

    Sample using Curl:

    curl --request POST 'http://localhost:8080/openidm/script?_action=eval' \
    --header 'X-OpenIDM-Username: openidm-admin' \
    --header 'X-OpenIDM-Password: openidm-admin' \
    --header 'Content-Type: application/json' \
    --data-raw '{"type" : "javascript", "source" : "String.fromCharCode.apply(String, org.forgerock.util.encode.Base64.decode('\''Q2xlYXIgVGV4dCBTdHJpbmc='\''));"}'



    Thanks for your response.

    I am getting below error on both local instance as well as on the Test system

    {"code":500,"reason":"Internal Server Error","message":"TypeError: second argument to Function.prototype.apply must be an array"}

    Also I am able to decode the base64 string using below

    	var base64 =
    	b64tO = new;"Decoded: {}", b64tO);

    Now I want to convert it into GUID.

    GUID is an arbitrary global unique identifier. You can encode/decode a GUID. But i am not sure what you mean by – “convert it into GUID”? GUID is usually a generated value.
