CyberChef is really useful, and it runs locally, so you never have to send your sensitive data to some random server anymore. The “recipes” feature is quite powerful, too, but I think my favorite thing about it is that I can often just paste random data in and run the “Magic” script and it’ll try to guess the data format for me.
> you never have to send your sensitive data to some random server anymore If you live in the UK you are already sending one entire month of your full personal communications, and three months of your communications metadata, to this government organisation. Pardon the off-topic rant.
Do we have decent reason to believe this is no longer the case for US citizens and the NSA, post-Snowden?
