But if they is any reason, why u need to post your address or private keys on social media, try to hex code it. Or random people will access your mail.
changing the encoding of an input does NOT improve your privacy at all. you would be fooling yourself into thinking otherwise. for example if i post 123 or 0x7b or 0b01111011 they all mean the same exact thing, an integer equal to one hundred and twenty three! besides when you post your address somewhere, you want others to be able to copy it and send you coins, adding a different encoding will just increase their work since they would have to convert it first before they can use it.
ps. it makes zero sense to post "private key" on the internet!
