| | OpenSSH - Wikipedia, the free encyclopedia |
 | | OpenSSH was created by the OpenBSD team as an alternative to the original SSH software by Tatu Ylönen, which is now proprietary software. | | | OpenSSH (Open Secure Shell) is a set of computer programs providing encrypted communication sessions over a computer network using the SSH protocol. | | | Although source code is available for the original SSH, various restrictions are imposed on its use and distribution, making OpenSSH a more attractive project for many software developers. |

| | OpenSSH has also added sftp(1) and sftp-server(8) which implement an easier solution for file-transfer. | | | The OpenSSH suite includes the ssh(1) program which replaces rlogin and telnet, and scp(1) which replaces rcp(1) and ftp(1). | | | They trust that their data is safe since nobody is supposed to know that there is sensitive information in the network, or because so much other data is transferred in the network. |

| | The 101 Uses of OpenSSH: Part I Linux Journal |
| | OpenSSH built on Groenvall's work (his version, called OSSH, is still available), adding support for later versions of the ssh protocol and modularizing its cryptographic mechanisms in such a way that it's possible to compile OpenSSH without any patented algorithms whatsoever (i.e., without support for ssh v.1 protocols, which depend on RSA). | | | OpenSSH has been part of OpenBSD ever since and is now portable to most version of UNIX. | | | Since this version of OpenSSH supports both RSA and DSA keys, it makes sense to minimize the amount of clutter ssh adds to /etc. |

| | The possibility of a remote hole in OpenSSH will always be there with code this complex, however the benefits of using it far outweigh the drawbacks versus similar remote login protocols. | | | One of the problems with OpenSSH, however, is it's excess complexity. | | | Because SSH became a "for-profit" program, OpenSSH has been rapidly gaining ground as a fully-functional replacement to the commercial SSH since it's conception. |
