Method Detail

encode

public static String encode(byte[] in)

Encodes the given bytes into a base-32 string.

Parameters:

in - the bytes to encode.

Returns:

The base-32 string, or null if in is null.

encode

public static String encode(byte[] in,
                            int off,
                            int len)

Encodes the given bytes into a base-32 string.

Parameters:

in - an array containing the bytes to encode.

off - the start offset of the data within in.

len - the number of bytes to encode.

Returns:

The base-32 string.

encodeWithDashes

public static String encodeWithDashes(byte[] in)

Encodes the given bytes into a base-32 string, inserting dashes after every 6 characters of output.

Parameters:

in - the bytes to encode.

Returns:

The formatted base-32 string, or null if in is null.

encodeWithDashes

public static String encodeWithDashes(byte[] in,
                                      int off,
                                      int len)

Encodes the given bytes into a base-32 string, inserting dashes after every 6 characters of output.

Parameters:

in - the bytes to encode.

off - the start offset of the data within in.

len - the number of bytes to encode.

Returns:

The formatted base-32 string.

decode

public static byte[] decode(String in)

Decodes the given base-32 string into bytes. Any non-base-32 characters are silently ignored.

Parameters:

in - the base-32 string to decode.

Returns:

The decoded bytes, or null if in is null.
