Method Details

mask

public static String mask(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

singleQuote

public static String singleQuote(String value)

Wrap the value in single quotes, or return null if value is null

Parameters:

value - The value to wrap in single quotes

Returns:

The quoted value
