### Method Detail

#### encodeString

    public static java.lang.String encodeString(java.lang.String s)

Encodes a string into Base64 format. No blanks or line breaks are inserted.

Parameters:
  `s` - A String to be encoded.
Returns:
  A String containing the Base64 encoded data.

#### encodeLines

    public static java.lang.String encodeLines(byte[] in)

Encodes a byte array into Base 64 format and breaks the output into lines of 76 characters. This method is compatible with `sun.misc.BASE64Encoder.encodeBuffer(byte[])`.

Parameters:
  `in` - An array containing the data bytes to be encoded.
Returns:
  A String containing the Base64 encoded data, broken into lines.

#### encodeLines

    public static java.lang.String encodeLines(byte[] in,
                               int iOff,
                               int iLen,
                               int lineLen,
                               java.lang.String lineSeparator)

Encodes a byte array into Base 64 format and breaks the output into lines.

Parameters:
  `in` - An array containing the data bytes to be encoded.
  `iOff` - Offset of the first byte in `in` to be processed.
  `iLen` - Number of bytes to be processed in `in`, starting at `iOff`.
  `lineLen` - Line length for the output data. Should be a multiple of 4.
  `lineSeparator` - The line separator to be used to separate the output lines.
Returns:
  A String containing the Base64 encoded data, broken into lines.

#### encode

    public static char[] encode(byte[] in)

Encodes a byte array into Base64 format. No blanks or line breaks are inserted in the output.

Parameters:
  `in` - An array containing the data bytes to be encoded.
Returns:
  A character array containing the Base64 encoded data.

#### encode

    public static char[] encode(byte[] in,
                int iLen)

Encodes a byte array into Base64 format. No blanks or line breaks are inserted in the output.

Parameters:
  `in` - An array containing the data bytes to be encoded.
  `iLen` - Number of bytes to process in `in`.
Returns:
  A character array containing the Base64 encoded data.

#### encode

    public static char[] encode(byte[] in,
                int iOff,
                int iLen)

Encodes a byte array into Base64 format. No blanks or line breaks are inserted in the output.

Parameters:
  `in` - An array containing the data bytes to be encoded.
  `iOff` - Offset of the first byte in `in` to be processed.
  `iLen` - Number of bytes to process in `in`, starting at `iOff`.
Returns:
  A character array containing the Base64 encoded data.

#### decodeString

    public static java.lang.String decodeString(java.lang.String s)

Parameters:
  `s` - A Base64 String to be decoded.
Returns:
  A String containing the decoded data.
Throws:
  `java.lang.IllegalArgumentException` - If the input is not valid Base64 encoded data.

#### decodeLines

    public static byte[] decodeLines(java.lang.String s)

Decodes a byte array from Base64 format and ignores line separators, tabs and blanks. CR, LF, Tab and Space characters are ignored in the input data. This method is compatible with `sun.misc.BASE64Decoder.decodeBuffer(String)`.

Parameters:
  `s` - A Base64 String to be decoded.
