Hi,
the man page of crypt(3) says the following:
For compatibility with historical versions of crypt(3), the setting may
consist of 2 bytes of salt, encoded as above, in which case an iteration
count of 25 is used, fewer perturbations of DES are available, at most 8
characters of key are used, and the returned value is a NUL-terminated
string 13 bytes in length.
However, the crypt() library function in FreeBSD 2.2.5 doesn't appear to be
compatible with older versions when given a 2 byte salt. In fact the code in
/usr/src/lib/libcrypt/crypt.c doesn't indicate that making this case special.
Is this a bug or am I in some way interpreting things wrongly ? Also is there
any way in FreeBSD 2.2.5 to make crypt compatible with old versions (short of
modifying the code).
