Fix data loss in unsigned int cast in PK This patch introduces some additional checks in the PK module for 64-bit systems only. The problem is that the API functions in the PK abstraction accept a size_t value for the hashlen, while the RSA module accepts an unsigned int for the hashlen. Instead of silently casting size_t to unsigned int, this change checks whether the hashlen overflows an unsigned int and returns an error.
