* OPTS_TYPE_HASH_COPY: This copies the original input hash line as it is into a buffer so that it can be used later. This is required if the original input hash line ships with the same data which is not copied into salt_t or esalt buffer because it is overhead data which is not used in any way. The hash line is copied to the buffer hash_info->orighash and can be used from the encoder function by simply returning hash_info->orighash. Please do not abuse this functionality, for two reasons: First, by being able to reconstruct the original hash line from only the hashcat data we verify that the correct amount of data has been stored in the hashcat memory structures (IOW, it is a good verification process). Second, the host memory requirement for saving this data increases drastically. * OPTS_TYPE_HASH_COPY: This copies the original input hash line as it is into a buffer so that it can be used later.
