OPENSSL-PASSPHRASE-OPTIONS(1)	    OpenSSL	 OPENSSL-PASSPHRASE-OPTIONS(1)

NAME
       openssl-passphrase-options - Pass phrase	options

SYNOPSIS
       openssl command [ options ... ] [ parameters ...	]

DESCRIPTION
       Several OpenSSL commands	accept password	arguments, typically using
       -passin and -passout for	input and output passwords respectively. These
       allow the password to be	obtained from a	variety	of sources. Both of
       these options take a single argument whose format is described below.
       If no password argument is given	and a password is required then	the
       user is prompted	to enter one: this will	typically be read from the
       current terminal	with echoing turned off.

       Note that character encoding may	be relevant, please see
       passphrase-encoding(7).

OPTIONS
   Pass	Phrase Option Arguments
       Pass phrase arguments can be formatted as follows.

       pass:password
	   The actual password is password. Since the password is visible to
	   utilities (like 'ps'	under Unix) this form should only be used
	   where security is not important.

       env:var
	   Obtain the password from the	environment variable var. Since	the
	   environment of other	processes is visible on	certain	platforms
	   (e.g. ps under certain Unix OSes) this option should	be used	with
	   caution.

       file:pathname
	   The first line of pathname is the password. If the same pathname
	   argument is supplied	to -passin and -passout	arguments then the
	   first line will be used for the input password and the next line
	   for the output password. pathname need not refer to a regular file:
	   it could for	example	refer to a device or named pipe.

       fd:number
	   Read	the password from the file descriptor number. This can be used
	   to send the data via	a pipe for example.

       stdin
	   Read	the password from standard input.
