Constructor Details

#initialize(fixed_length, keep_start_count, keep_end_count) ⇒ ValueObfuscator

Creates a new ValueObfuscator.

Parameters:

  • fixed_length (Integer) —

    if greater than 0, all values that will be obfuscated will be replaced with that number of asterisks.

  • keep_start_count (Integer) —

    the number of characters to not obfuscate at the end of any value. This parameter is only used if fixed_length = 0.

  • keep_end_count (Integer) —

    the number of characters to not obfuscate at the start of any value. This parameter is only used if fixed_length = 0.
