NAME

passwd — compute password hashes

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.
