- <simpara>
- On systems where the system's crypt() function defaults to using MD5, the
- salt is not a simple 2-character string like it has traditionally always
- been. This function will return the length of the salt component of the
- encrypted string.

           2-character DES salt by default unless the default encryption type
           on the system is MD5 in which case a random MD5-compatible salt
! is generated. PHP sets a constant named CRYPT_SALT_LENGTH which
! tells you whether a regular 2-character salt applies to your system
! or the longer 12-char MD5 salt is applicable.
