I'm working on a custom module that relies upon some properties from Admin user model. I used the method
hashPassword() in my custom model replicated from core customer model, and in there, there is a call for constant
Mage_Admin_Model_User::HASH_SALT_LENGTH. When I was working with version 1.9, all was good to go, but then I needed to port the module for 1.6, and there started my problem.
Turns out that above constant is not defined in 1.6, tried with
defined(Mage_Admin_User_Model::HASH_SALT_LENGTH), but no success.
Magento 1.6 had the value hard-coded to 2, and 1.9 has this value in constant as 32.
Looking for a better approach than to just hard-code the value so in versions in-between, I can use the same value being used by core code.
