Another very commonly used authentication method is publickey authentication, which is based on public key encryption.
SSH-2 uses a layered architecture, consisting of a transport layer, a user authentication layer, and a connection layer (described here). The previous post in this series explained the transport layer,…
This post will explain the main features of the transport layer.
SSH is a secure network protocol that can used used on any platform for any purpose requiring secure network communication.
Like any secure protocol, vulnerabilities will continue to be discovered, and it is important to keep software that utilises TLS up-to-date so that the latest security patches are applied.
The previous post in this series about SSL/TLS described the handshake - the process that establishes an SSL/TLS session between client and server. The session includes agreed-upon encryption keys. Now,…
As part one explained, SSL/TLS is intended to provide secure network connections between a client (e.g. a web browser), and a server (e.g. a web server) by encrypting all data…
History The Secure Sockets Layer (SSL) is a cryptographic protocol designed to secure communications over TCP/IP networks. SSL was developed by Netscape during the early 1990's, but various security flaws…
In How does public key encryption work?, it was explained that there needs to be a way of reliably associating public keys with their owners. Using someone's public key to…
