Remarks

The SpinCount property specifies the number of times the hashing function shall be iteratively run (using each iteration’s result as the input for the next iteration) when attempting to compare a user supplied password with the hash data. That is, it specifies the number of iterations used to calculate the Strong Password Verifier; by default, 100 000. High SpinCount values strengthen protection but decrease performance.

The property is in effect only if the SpreadsheetProtectionOptions.UseStrongPasswordVerifier property is set to true.
