Hey @hslee

We don’t have a direct option to encrypt / decrypt files. The best option I can think of would be to use the code node with the included crypto package and do it that way.

Thanks for your reply.
Is it possible for the code node to include(require?) "crypto’ package?

Hey @hslee,

Yeah that is possible, If you use Cloud it is already available if you are self hosting you will need to configure NODE_FUNCTION_ALLOW_BUILTIN and set it to crypto

I use self host n8n.
I didn’t know the exstence and the use of NODE_FUNCTION_ALLOW_BUILTIN.

I’ll follow your advice. Thanks for your help.
