```
public static boolean isArrayByteBase64(byte[] arrayOctect)
```
    Tests a given byte array to see if it contains only valid characters within the Base64 alphabet.
    
    参数:
    
    arrayOctect - byte array to test
    
    返回:
    
    true if all bytes are valid characters in the Base64 alphabet or if the byte array is empty; false, otherwise
  - encodeBase64
```
public static byte[] encodeBase64(byte[] binaryData)
```
    Encodes binary data using the base64 algorithm but does not chunk the output.
    
    参数:
    
    binaryData - binary data to encode
    
    返回:
    
    Base64 characters
  - encodeBase64Chunked
```
public static byte[] encodeBase64Chunked(byte[] binaryData)
```
    Encodes binary data using the base64 algorithm and chunks the encoded output into 76 character blocks
    
    参数:
    
    binaryData - binary data to encode
    
    返回:
    
    Base64 characters chunked in 76 character blocks
  - decode
```
public Object decode(Object pObject)
              throws DecoderException
```
    Decodes an Object using the base64 algorithm. This method is provided in order to satisfy the requirements of the Decoder interface, and will throw a DecoderException if the supplied object is not of type byte[].

    参数:
    
    pObject - Object to decode
    
    返回:
    
    An object (of type byte[]) containing the binary data which corresponds to the byte[] supplied.
    
    抛出:
    
    DecoderException - if the parameter supplied is not of type byte[]
  - decode
```
public byte[] decode(byte[] pArray)
```
    Decodes a byte[] containing containing characters in the Base64 alphabet.
    
    指定者:
