Now, whilst having said that, I do want to comment more on HTTPS more; HTTPS although fine to use, it's not the best way to encrypt traffic, actually, I2P, again, is a far superior technology as far as encrypted connections go. HTTPS has useless third parties that need to be trusted and I2P is fundamentally end-to-end encrypted, so the best thing to use is still just HTTP, when on I2P.
