OpenSSH can use either the RSA or DSA algorithms for public-key authentication. RSA stands for Rivest, Shamir and Adleman, the last names of the MIT team members who developed it. DSA stands for Digital Signature Algorithm, a US Government standard proposed by the National Institute of Standards and Technology. OpenSSH is the premier connectivity tool for remote login with the SSH protocol. It encrypts all traffic to eliminate eavesdropping, connection hijacking, and other attacks. In addition, OpenSSH provides a large suite of secure tunneling capabilities, several authentication methods,. If you want to be able to log in without typing in your password, first create /.ssh/idrsa and /.ssh/idrsa.pub with ssh-keygen and then copy /.ssh/idrsa.pub to /.ssh/authorizedkeys on the remote computer that you want to log into. You'll need to change REMOTEUSERNAME and REMOTEHOSTNAME for the username and hostname of the remote.

HISTORY
Initially, the manual page entry for the openssl cmd command used to be available at cmd(1). Later, the alias openssl-cmd(1) was introduced, which made it easier to group the openssl commands using the apropos(1) command or the shell's tab completion.
In order to reduce cluttering of the global manual page namespace, the manual page entries without the 'openssl-' prefix have been deprecated in OpenSSL 3.0 and will be removed in OpenSSL 4.0.
