Anonymization

Node for hashing (SHA-1) the values in the columns with multiple salting strategies.

Options

Salting
The node applies SHA-1 algorithm for hashing values in selected columns. All values are converted to string then additional information might be concatenated to this string for salting. There are four salting strategies:
  • None - values in selected columns are hashed as they are, no additional concatenation is used;
  • Random - random seed is used for salting every time node is executed. It is possbile to use a fixed seed value.
  • Column - values from additional column is used for salting. Values from selected columns are concatenated row-wise.
  • Timestamp - selected date and time are used for salting.
Debug Mode
If activated no hashing will be applied, instead only values with or without salting will be returned.
