Synopsis

openssl passwd
[-crypt]
[-1]
[-apr1]
[-salt string]
[-in file]
[-stdin]
[-noverify]
[-quiet]
[-table]
{password}

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 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).
-salt string
Use the specified salt. When reading a password from the terminal, this implies -noverify.
-in file
Read passwords from file.
-stdin
Read passwords from stdin.
-noverify
Don't verify when reading a password from the terminal.
-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$UYCIxa628.9qXjpQCjM4a..

openssl passwd -apr1 -salt xxxxxxxx password prints $apr1$xxxxxxxx$dxHfLAsjHkDRmG83UXe8K0.
