We need to check all files to/from customers on uniqueness based on SHA1 hash.
a. Calculate SHA1 hash of a file
b. is this hash already present in a specified named list?
c. If not in list, add it to the named list
d. If hash does occur, exception handling
e. Named list cleanup (days validity of the hash)
How can this be done in a MFT workflow?
Are there already functions/tasks in MFT we can use for his?
