Having a base64 decoding problem in Splunk 9- How to decode Idap-events?

After installing splunk 9 we have a problem with decoding ldap-events. We tried several apps but none of them gave us correct results.

We wanted to use the app "Encode / Decode Data for Splunk" but we can't find any instructions of how to use it.

Does anyone have experience with base64 decoding in splunk 9?

We had the same problem initially and found more details about code command usage under \TA-code\default\searchbnf.conf

We are able to decode the URL or process using | code method=base64 field=encodedcommand action=decode destfield=decoded_command key=abc123 but when we stats the decoded_command it gives the result as "p".

I tried the base64 conversion matrix macro as well, it does the same p thing.

Later we have used an app named decrypt2 and it worked for us with this syntax:

 

| decrypt field=randomfield atob emit('randomfielddecrypt')

Answering my own question:

Syntax is like this:

| code field=randombase64field method=base64 action=decode destfield=test 

unfortunately it doesn't decode diacritics correctly.

Does someone have a solution for that? Apps that worked fine in splunk 8 don't seem to work correct in splunk 9.
