crypt(3) is the C language interface. Or perl will let you get at it
from the command line. The format of the salt determines the
encryption algorithm used:
Eg. DES just uses two characters:
% perl -e 'print crypt("password", "xx"), "\n";'
xxj31ZMTZzkVA
whereas MD5 uses the 'Modular' format and an 8 character salt:
% perl -e 'print crypt(q{password}, q{$1$xxxxxxxx$}), "\n";'
$1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a.
Only MD5 and DES are available in FreeBSD 4.x --- other systems may
support Blowfish using salts that start $2$
