Hello there,
Apologies for emailing out of the blue, my name is Louis and I’m a compsci student based in London currently working on a project looking at potential vulnerabilities in Github SSH keys.
I am looking to pay $100 for Github SSH or PGP keys that are deprecated and at least a year old. You would need to deprecate the key i.e. delete from your account, before you send it to me so that it's not associated with any live repositories (takes about 2 mins and removes any security risks on your end).
I'll pay upfront by PayPal, do let me know if this is something you’d be keen to help out with-- and more than happy to send more info on my project and research if you'd like!
Best,
Emerson Louis
