        "DESCRIPTION": {
            "content": "Several OpenSSL commands accept password arguments, typically using\n-passin and -passout for input and output passwords respectively. These\nallow the password to be obtained from a variety of sources. Both of\nthese options take a single argument whose format is described below.\nIf no password argument is given and a password is required then the\nuser is prompted to enter one: this will typically be read from the\ncurrent terminal with echoing turned off.\n\nNote that character encoding may be relevant, please see\npassphrase-encoding(7).\n",

        "OPTIONS": {
            "content": "Pass Phrase Option Arguments\nPass phrase arguments can be formatted as follows.\n\npass:password\nThe actual password is password. Since the password is visible to\nutilities (like 'ps' under Unix) this form should only be used\nwhere security is not important.\n\nenv:var\nObtain the password from the environment variable var. Since the\nenvironment of other processes is visible on certain platforms\n(e.g. ps under certain Unix OSes) this option should be used with\ncaution.\n\nfile:pathname\nThe first line of pathname is the password. If the same pathname\nargument is supplied to -passin and -passout arguments then the\nfirst line will be used for the input password and the next line\nfor the output password. pathname need not refer to a regular file:\nit could for example refer to a device or named pipe.\n\nfd:number\nRead the password from the file descriptor number. This can be used\nto send the data via a pipe for example.\n\nstdin\nRead the password from standard input.\n",
