An offline root certificate authority is a certificate authority (as defined in the X.509 standard and RFC 5280) which has been isolated from network access, and is often kept in a powered-down state. In a public key infrastructure, the chain of trusted authorities begins with the root certificate authority (root CA).
OCSP-based revocation is not an effective technique to mitigate against the compromise of an HTTPS server's private key. An attacker who has compromised a server's private key typically needs to be in a man-in-the-middle position on the network to abuse that private key and impersonate a server. An attacker in such a position is also typically ...
OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping, and identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites. OpenSSL contains an open-source implementation of the SSL and TLS protocols.
In 2006, this patch was then ported to the development branch of OpenSSL, and in 2007 it was back-ported to OpenSSL 0.9.8 (first released in 0.9.8f [38]). First web browsers with SNI support appeared in 2006 (Mozilla Firefox 2.0, Internet Explorer 7), web servers later (Apache HTTP Server in 2009, Microsoft IIS in 2012).
Heartbleed could be exploited regardless of whether the vulnerable OpenSSL instance is running as a TLS server or client. It resulted from improper input validation (due to a missing bounds check ) in the implementation of the TLS heartbeat extension. [ 5 ]

In cryptography and computer security, a root certificate is a public key certificate that identifies a root certificate authority (CA). [1] Root certificates are self-signed (and it is possible for a certificate to have multiple trust paths, say if the certificate was issued by a root that was cross-signed) and form the basis of an X.509 ...
