`byte[]`	`decode(byte[] pArray)` Decodes a byte[] containing containing characters in the Base64 alphabet.
`java.lang.Object`	`decode(java.lang.Object pObject)` Decodes an Object using the base64 algorithm.
`static byte[]`	`decodeBase64(byte[] base64Data)` Decodes Base64 data into octects
`byte[]`	`encode(byte[] pArray)` Encodes a byte[] containing binary data, into a byte[] containing characters in the Base64 alphabet.
`java.lang.Object`	`encode(java.lang.Object pObject)` Encodes an Object using the base64 algorithm.
`static byte[]`	`encodeBase64(byte[] binaryData)` Encodes binary data using the base64 algorithm but does not chunk the output.
`static byte[]`	`encodeBase64(byte[] binaryData, boolean isChunked)` Encodes binary data using the base64 algorithm, optionally chunking the output into 76 character blocks.

  - isArrayByteBase64
```
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 java.lang.Object decode(java.lang.Object pObject)
```
    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:
    
    java.security.InvalidParameterException - 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.
    
    参数:
    pArray - A byte array containing Base64 character data
    
    返回:
    a byte array containing binary data
  - encodeBase64
```
public static byte[] encodeBase64(byte[] binaryData,
                  boolean isChunked)
```
    Encodes binary data using the base64 algorithm, optionally chunking the output into 76 character blocks.
    
    参数:
    binaryData - Array containing binary data to encode.
    isChunked - if isChunked is true this encoder will chunk the base64 output into 76 character blocks
    
    返回:
    Base64-encoded data.
  - decodeBase64
```
public static byte[] decodeBase64(byte[] base64Data)
```
    Decodes Base64 data into octects
    
    参数:
    base64Data - Byte array containing Base64 data
    
    返回:
    Array containing decoded data.
  - encode
```
public java.lang.Object encode(java.lang.Object pObject)
```
    Encodes an Object using the base64 algorithm. This method is provided in order to satisfy the requirements of the Encoder interface, and will throw an EncoderException if the supplied object is not of type byte[].
    
    参数:
    pObject - Object to encode
    
    返回:
    An object (of type byte[]) containing the base64 encoded data which corresponds to the byte[] supplied.
    
    抛出:
    
    java.security.InvalidParameterException - if the parameter supplied is not of type byte[]
  - encode
```
public byte[] encode(byte[] pArray)
```
    Encodes a byte[] containing binary data, into a byte[] containing characters in the Base64 alphabet.
    
    参数:
    pArray - a byte array containing binary data
    
    返回:
    A byte array containing only Base64 character data
