.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is turned on, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
"NAME"
passwd - compute password hashes
"SYNOPSIS"
Header "SYNOPSIS" \fBopenssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] {password}
"DESCRIPTION"
Header "DESCRIPTION" The passwd command computes the hash of a password typed at run-time or the hash of each password in a list. The password list is taken from the named file for option -in file, from stdin for option -stdin, or from the command line, or from the terminal otherwise. The Unix standard algorithm crypt and the MD5-based \s-1BSD\s0 password algorithm 1 and its Apache variant apr1 are available.
"OPTIONS"
Header "OPTIONS"
"-crypt" 4
Item "-crypt" Use the crypt algorithm (default).
"-1" 4
Item "-1" Use the \s-1MD5\s0 based \s-1BSD\s0 password algorithm 1.
"-apr1" 4
Item "-apr1" Use the apr1 algorithm (Apache variant of the \s-1BSD\s0 algorithm).
"-salt string" 4
Item "-salt string" Use the specified salt. When reading a password from the terminal, this implies -noverify.
"-in file" 4
Item "-in file" Read passwords from file.
"-stdin" 4
Item "-stdin" Read passwords from stdin.
"-noverify" 4
Item "-noverify" Don't verify when reading a password from the terminal.
"-quiet" 4
Item "-quiet" Don't output warnings when passwords given at the command line are truncated.
"-table" 4
Item "-table" In the output list, prepend the cleartext password and a \s-1TAB\s0 character to each password hash.
"EXAMPLES"
Header "EXAMPLES" \fBopenssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA.

\fBopenssl passwd -1 -salt xxxxxxxx password prints \f(CB$1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a..

\fBopenssl passwd -apr1 -salt xxxxxxxx password prints \f(CB$apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
