mill.tools.Base64
- public final class Base64
- extends java.lang.Object
This class provides encode/decode for RFC 2045 Base64 as
defined by RFC 2045, N. Freed and N. Borenstein.
RFC 2045: Multipurpose Internet Mail Extensions (MIME)
Part One: Format of Internet Message Bodies. Reference
1996 Available at: http://www.ietf.org/rfc/rfc2045.txt
This class is used by XML Schema binary format validation
This implementation does not encode/decode streaming
data. You need the data that you will encode/decode
already on a byte arrray.

isArrayByteBase64
public static boolean isArrayByteBase64(byte[] arrayOctect)
encode
public static byte[] encode(byte[] binaryData)
- Encodes hex octects into Base64
decode
public static byte[] decode(byte[] base64Data)
- Decodes Base64 data into octects
getDecodedDataLength
public static int getDecodedDataLength(byte[] base64Data)
- returns length of decoded data given an
