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, and from the command line otherwise.
The Unix standard algorithm crypt and the MD5-based BSD password
algorithm 1 and its Apache variant apr1 are available.
OPTIONS
-crypt
Use the crypt algorithm (default).
-1
Use the MD5 based BSD password algorithm 1.
-apr1
Use the apr1 algorithm (Apache variant of the BSD algorithm).
-saltstring
Use the specified salt.
-infile
Read passwords from file.
-stdin
Read passwords from stdin.
-quiet
Don't output warnings when passwords given at the command line are truncated.
-table
In the output list, prepend the cleartext password and a TAB character
to each password hash.
EXAMPLES
openssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA.
openssl passwd -1 -salt xxxxxxxx password prints $1$xxxxxxxx$8XJIcl6ZXqBMCK0qFevqT1.
openssl passwd -apr1 -salt xxxxxxxx password prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
