EagleML Hash Check Sum is an optional process which allows to ensure data integrity of data loaded. The idea here is to perform a checksum on the entire payload, not to use a designated column with a numeric value. Eagle identifies the default checksum/hash utility and runs it on UNIX or Windows.
Algorithm and Utilities
EagleML Hash Check Sum uses SHA256 (SHA-2) algorithm.
Unix - sha256sum command from CoreUtilities packet
Windows - certUtil tool with -hashfile command

Hash Sum Calculation
EagleML uses get_hash_sum.inc include to calculate the hash sum with SHA-2 algorithm. When the hash sum is resolved, utility returns it either in format for UNIX:
...
Output parameters:
:varHashSum:
:varHashSummError:
