            "content": "Several OpenSSL commands accept password arguments, typically using -passin and -passout for\ninput and output passwords respectively. These allow the password to be obtained from a\nvariety of sources. Both of these options take a single argument whose format is described\nbelow. If no password argument is given and a password is required then the user is prompted\nto enter one: this will typically be read from the current terminal with echoing turned off.\n\nNote that character encoding may be relevant, please see passphrase-encoding(7).\n",

                    "content": "Pass phrase arguments can be formatted as follows.\n\npass:password\nThe actual password is password. Since the password is visible to utilities (like 'ps'\nunder Unix) this form should only be used where security is not important.\n\nenv:var\nObtain the password from the environment variable var. Since the environment of other\nprocesses is visible on certain platforms (e.g. ps under certain Unix OSes) this option\nshould be used with caution.\n\nfile:pathname\nThe first line of pathname is the password. If the same pathname argument is supplied to\n-passin and -passout arguments then the first line will be used for the input password\nand the next line for the output password. pathname need not refer to a regular file: it\ncould for example refer to a device or named pipe.\n\nfd:number\nRead the password from the file descriptor number. This can be used to send the data via\na pipe for example.\n"
