 Each module provides the functions `module_constraints`, `module_generate_hash` and `module_verify_hash`.
 
 * The `module_constraints` function should return the minimum and maximum length of the password, salt and the combination of password and salt in following order: password (pure), salt (pure), password (optimized), salt (optimized) and combination (optimized). 
-Each pair should be set to -1 if the hash mode is not supporting the appropriate field. For example, if a hash-mode does not support a salt, it should be set to -1. The last field (combination) is important if the the password and the salt is stored in the same buffer in the kernel (typically raw hashes only).

The last field (combination) is important if the password and the salt is stored in the same buffer in the kernel (typically raw hashes only). 
 * The first parameter to `module_generate_hash` is the password, which can be either in ASCII or binary (packed) form. The second parameter is the salt *which can be undefined for unsalted hash modes). 
 * The `module_verify_hash` function accepts a line from the cracks file, without the newline characters.
