Meh, the server doesn’t support the latest versions of the TLS protocol:
SSL Labs results for the MIRCS site
This is bad if the site accepts credit cards (it doesn’t) because the PCI DSS disallowed TLS 1.0 in mid 2018. Otherwise, it’s only a nuisance. The most recent versions of chrome (and Mozilla) are throwing warnings and promise to actually break access to sites supporting less than TLS 1.2 (which is what
@milktree was alluding to - no tinfoil needed) in 2021.
NO, your data is NOT in clear text. TLS 1.0 has been shown in the lab to be susceptible to “man in the middle” eavesdropping, but its hardly trivial to achieve that and mircs isn’t a high value target to waste the effort on.
