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.
