Secure Shell (SSH): Public Key Authentication over Hypertext Transfer Protocol (HTTP)

The Secure Shell (SSH) protocol requires all implementations to support public key authentication method (“publickey”) for authentication purposes [2]. Hypertext Transfer Protocol (HTTP) applications which provide a SSH client over the web browser need to support “publickey”. However, restrictions in HTTP, such as Same Origin Policy, make it difficult to perform such authentications. In this document, a system to perform “publickey” authentication over HTTP is provided. It is ensured that no compromise is made that would pose a security risk to SSH protocol.
