What you mean is the default encryption type.

The trick here is not to provide *a salt*, but to provide such salt
that will make system crypt function produce an MD5 hash. This does
not depend on the default encryption type. The FreeBSD crypt()
documentation says:


   The algorithm used will depend upon the format of the
   Salt (following the Modular Crypt Format (MCF)), if DES and/or
   Blowfish is installed or not, and whether crypt_set_format() has been
   called to change the default.
   [...]


For MD5 hashes, the salt value must have the form:

    $1$<the_salt>$

where <the_salt> means the salt sequence itself.

Refer to `man 3 crypt' for more info.
