.. 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. | will give a
real vertical bar. \*(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<>

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

For nroff, turn off justification. Always turn off hyphenation; it
makes way too many mistakes in technical documents.

Accent mark definitions (@(#)ms.acc 1.5 88/02/08 SMI; from UCB 4.2).
Fear. Run. Save yourself. No user-serviceable parts.

Title "PASSWD 1" C passwd - compute password hashes Header "SYNOPSIS" \fBopenssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin] [-noverify] [-quiet] [-table] {password} 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. Header "OPTIONS" p "-crypt" 4 Item "-crypt" Use the crypt algorithm (default). p "-1" 4 Item "-1" Use the \s-1MD5\s0 based \s-1BSD\s0 password algorithm 1. p "-apr1" 4 Item "-apr1" Use the apr1 algorithm (Apache variant of the \s-1BSD\s0 algorithm). p "-salt string" 4 Item "-salt string" Use the specified salt. When reading a password from the terminal, this implies -noverify. p "-in file" 4 Item "-in file" Read passwords from file. p "-stdin" 4 Item "-stdin" Read passwords from stdin. p "-noverify" 4 Item "-noverify" Don't verify when reading a password from the terminal. p "-quiet" 4 Item "-quiet" Don't output warnings when passwords given at the command line are truncated. p "-table" 4 Item "-table" In the output list, prepend the cleartext password and a \s-1TAB\s0 character to each password hash. Header "EXAMPLES" \fBopenssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA.

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

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