I'll do that if you don't see any other solution.

Thank you,

Guillaume

Why don't you save the decoded value in "msg[data]" (whatever that is) in the first place?

I must have misspoken. What I want to do is that I have base64 encoded data in my msg.data and I want to modify my source.url in the modify expert to have XXXX={msg[data]} in decoded version.

Today when I do this on the modify expert, it gives me:
XXXX=YmFzZTY0ZGF0YQ==

while I would like:
XXXX=base64data

All this without modifying the rest of my configuration, I know I could add a temporary field in harmonization.conf that contains my decrypted data, but I don't find it very clean.

You don't often get email from mika.silander at csc.fi<mailto:mika.silander at csc.fi>. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification>
Hi Guillaume,

 Not entirely sure as to why you need to decode parts of your Modify expert's configurations, but in intelmq/lib/utils.py you have the base64_encode and base64_decode functions that may be of use to you.
Testing and experimenting what decoded and encoded data looks like can also be achieved on the command line, e.g. (on Ubuntu with the base64 executable provided by the coreutils package):

echo "a text sample" | base64 | base64 -d -

gives

a text sample

 I hope this helps.

Br, Mika

Subject: [IntelMQ-users] Modify expert get the value of data

Hello,

This may be a silly question, but I can't find the answer.
Is it possible to get the decoded value (not base 64) of my data in a configuration file of the bot intelmq.bots.experts.modify.expert?

I would like to do something like that with the decoded value:
