EmerSSL is a system for passwordless website login and identification using the Emercoin blockchain as a decentralized trust store of hash sums for client SSL-certificates. Certificates can be generated by users on their own computer, without any central authority, and quickly replaced as needed. This makes the system effective both for scheduled replacement and rapid recall of compromised certificates.

The advantage provided by EmerSSL is in the complete decentralization of the system, i.e. the lack of a group of servers running under a single authorization (as used in the systems of Kerberos, OpenID, TeddyID and the like). Due to this decentralization it is not possible for EmerSSL to suffer a system-wide service disruption either due to technical failure or malicious attack upon authorization servers. In addition, it is not possible for a user to have their accounts globally suspended at the whim of a single authority.

Associated with the EmerSSL technology is EmerSSL InfoCard - a "business card" system that complements EmerSSL's passwordless logins by allowing website profiles to be automatically populated from data residing on the Emercoin blockchain.
