Quite the opposite. Compared to SSH, SSL is a complete and utter failure. SSH became popular in 1995 and ubiquitous on Unix platforms before 2000. Probably >>95% of all admins of networked Unix boxes have SSH configured and used it to access their machines remotely. Many of them have been doing this for >10 years. Even lots of networked devices support SSH out-of-the-box (DSL-router, DVB-S receiver, Home-NAS) and SSH is quite easy to configure for use with these devices. In comparison, the number of Web-Servers that are accessible via SSL/TLS (HTTPS) is completely negligible. From that fraction of the Web-Servers that have some service running on port 443 it is around 97% that do not support SSL/TLS access. Considering the intimidating Scare-pages of newer Web-Browsers for Servers using self-signed certs, the Browser-Vendors reliably killed the usage-scenario to use TLS to access your Home-NAS, DSL-Router or DVB-S receiver, because going through the pain to obtain and yearly renew TLS certs for each and every device -- in particular for the shortcut hostnames that people are typically using at home, which most Browser-blessed CAs are unlikely to issue certs for anyway. The most recent developments in TLS are likely to cut back the use of TLS to only public commercial services. The Scare-Pages of recent Browsers are sure killers for any intra-Home-applicability of TLS and the standardization efforts around "server identification" (certid) are likely to make things worse, because they are similarly preoccupied with commercial CA certs and bureaucratic hierarchical namespace management. Being able to easily network a small number of computers and network-attached devices at home without involvement of outside third parties is a pretty common use case. It is where SSH started and excels in. It is where TLS hardly worked from the beginning and where it has become much worse since due to the Scare-Consumers-Away-From-This-Technology pages in recent Browsers. -Martin
