Hello everybody,
I noticed that all pages of IOHK, Emurgo etc. are SSL encrypted, but they only use normal certificates. These have the advantage that they offer a valid SSL encryption, but under certain circumstances a typo domain for a visitor is not so easy to distinguish from the real website. A clear advantage would be EV (extended validation) certificates, which are also optically clearly emphasized.
Meanwhile EV certificates are not as much more expensive than normal certificates.
