PASSWD

passwd ? compute password hashes

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

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 apr1 algorithm are available.

?crypt

Use the crypt algorithm (default).

?apr1

Use the apr1 algorithm.

?salt string

Use the specified salt.

?in file

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.

openssl passwd ?crypt ?salt xx password prints xxj31ZMTZzkVA.

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