Method Detail

• decode

  public static byte[] decode​(java.lang.String str)

  Decode given string into a decoded byte array.

  Parameters:

  str - Base64 String to be decoded.

  Returns:

  All decoded octets as byte array.

• translate

  public void translate​(java.lang.String string)

  Translate every base64 character from given string into a sextet byte value by using above translation array. The sextets are then shiftet into an buffer until the buffer contains 4 sextets which are then decoded into 3 octets. The translate and decode process is continued until all characters of given string are evaluated. If there are remaing sextets in the buffer they also will be converted into octets at the end. All the converted octets are added to the list for later read.

  Parameters:

  string - Base64 String to be decoded.

• getByteArray

  public byte[] getByteArray()

  Get all decoded octets as byte array.
