NAME

6       openssl-passphrase-options - Pass phrase options
7

SYNOPSIS

9       openssl command [ options ... ] [ parameters ... ]
10

DESCRIPTION

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

OPTIONS

24   Pass Phrase Option Arguments
25       Pass phrase arguments can be formatted as follows.
26
27       pass:password
28           The actual password is password. Since the password is visible to
29           utilities (like 'ps' under Unix) this form should only be used
30           where security is not important.
31
32       env:var
33           Obtain the password from the environment variable var. Since the
34           environment of other processes is visible on certain platforms
35           (e.g. ps under certain Unix OSes) this option should be used with
36           caution.
37
38       file:pathname
39           The first line of pathname is the password. If the same pathname
40           argument is supplied to -passin and -passout arguments then the
41           first line will be used for the input password and the next line
42           for the output password. pathname need not refer to a regular file:
43           it could for example refer to a device or named pipe.
44
45       fd:number
46           Read the password from the file descriptor number. This can be used
47           to send the data via a pipe for example.
48
49       stdin
50           Read the password from standard input.
