Method Detail

mask

public static java.lang.String mask(java.lang.String input)

Return masked input text. Masking checks the length of input. If less than 8 it returns '**********'. If less than 20 it prints out first letter in clear text, and then additional 9x '*' irrespective of actual input size. If input length is greater than 20 chars, it prints out first 4 in clear text followed by '***..***' followed by last 4. The idea is to give some information for debugging while not leaking too much information about secrets.

Parameters:

input - String with sensitive date which should be masked

Returns:

The new masked string
