3.4.1 2025-04-03 OPENSSL-CMDS(1SSL)
Description
Every cmd listed above is a (sub-)command of the openssl(1) application. It has its own detailed manual
page at openssl-cmd(1). For example, to view the manual page for the openssldgst command, type "man
openssl-dgst".
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.
