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.
