Default password encryption method.

[ian ivy]

Hello,

By default FreeBSD uses MD5 to encrypt passwords. MD5 is believed to be
more secure than e.g. DES but less than e.g. SHA512. Currently several
major Linux distributions, uses a SHA512 mechanism. Suse Linux also offers
a blowfish.

Some Debian based distributions use MD5-based algorithm compatible with the
one
used by recent releases of FreeBSD - but mostly this variable (*
MD5_CRYPT_ENAB*)
is deprecated, and SHA512-based algorithm is used.

Of course, in FreeBSD we can change the MD5 for example to BLF,
but, it will be not a better solution to use SHA512 by default?
