By default, the shredding service uses three passes to overwrite the areas where the object data, secondary metadata, and custom metadata were stored. The three passes are applied to the entire object, repeating for each 128-KB block. Each pass has this pattern:
1.Set to a specified value
2.Set to the complement of that value
3.Set to a random value
4.Verify the value by reading it back
To use a different shredding algorithm, please contact your authorized HCP service provider.
