- public abstract class Base64
- extends java.lang.Object
The abstract Base64
class provides static methods to convert
back and forth between binary and base64-encoded data.
Method Summary |
(package private) static void |

The class initializer is responsible to set up the mapping from the
base64 alphabet (ASCII-based) to binary 0-63. |
static int |
decode(byte[] encodedData,

int length,
byte[] binaryData,
int binaryOffset)
Converts base64 encoded data into binary data. |
static int |
encode(byte[] binaryData,
int binaryOffset,

encodingBase64Alephbeth
private static final byte[] encodingBase64Alephbeth
- Mapping from binary 0-63 to base64 alphabet according to RFC 2045.
(Yes, I do know that the Hebrew alphabet has only 22 letters.)
decodingBase64Alephbeth
private static final byte[] decodingBase64Alephbeth
- Mapping from base64 alphabet to binary 0-63.
Base64
public Base64()
encode
public static int encode(byte[] binaryData,
int binaryOffset,
int length,
byte[] encodedData,
int encodedOffset)
- Converts binary data into base64 encoded data.
- Parameters:
binaryData
- Binary data to be encoded.binaryOffset
- Offset into binaryData
where to
the data to be encoded begins.length
- Length of data to encode.encodedData
- Buffer receiving base64 encoded data.encodedOffset
- Offset into encodedData
where the
store base64 encoded data.- Returns:
- Length of encoded base64 data.
decode
public static int decode(byte[] encodedData,
int encodedOffset,
int length,
byte[] binaryData,
int binaryOffset)
- Converts base64 encoded data into binary data.
- Parameters:
encodedData
- Base64 encoded data.encodedOffset
- Offset into encodedData
where the
base64 encoded data starts.length
- Length of encoded data.binaryData
- Decoded (binary) data.binaryOffset
- Offset into binaryData
where to
store the decoded binary data.- Returns:
- Length of decoded binary data.
