- ## Method Details

  - ### decode

    public static byte[] decode(byte[] in)

  - ### decode

    public static byte[] decode(byte[] in, int len)

    Decodes an array of bytes containing a Base64 ascii string into binary data

    ###### Parameters

    - `in`: the array

    - `len`: the length of the array

    ###### Returns

    the decoded array

  - ### decode

    public static int decode(byte[] in, int len, byte[] out)
    Decodes Base64 input into a caller-provided output buffer.
    Parameters:
      `in` - Base64 bytes
      `len` - bytes from `in` to decode
      `out` - destination buffer
    Returns:
      decoded length, or `-1` for invalid Base64

  - ### decode

    public static int decode(byte[] in, byte[] out)

  - ### encode

    public static String encode(byte[] in)

    Encodes the given array as a base64 string

    ###### Parameters

    - `in`: the array to encode

    ###### Returns

    the String containing the array

  - ### encodeNoNewline

    public static String encodeNoNewline(byte[] in)

    Encodes the given array as a base64 string without breaking lines

    ###### Parameters

    - `in`: the array to encode

    ###### Returns

    the String containing the array

  - ### encodeNoNewline

    public static int encodeNoNewline(byte[] in, byte[] out)
    Encodes input into a caller-provided output buffer without line breaks.
    Parameters:
      `in` - input bytes
      `out` - destination buffer
    Returns:
      number of bytes written to `out`
