encodeSensitiveStringToUtf8
public static byte[] encodeSensitiveStringToUtf8(char[] str) Converts a char-array to UTF-8 byte-array and then blanks out source array and all intermediate arrays. This is useful when a plaintext password needs to be encoded as UTF-8.- Parameters:
str
- A not-null string as a character array.- Returns:
- UTF-8 bytes of the string
