Method Detail

decode

public static byte[] decode(char[] chars)

Decodes base64 characters into bytes. Newline characters found at block boundaries will be ignored.

Parameters:

chars - The characters array to decode.

Returns:

The decoded byte array.

decode

public static byte[] decode(String encodedString)

Decodes a base64 string into bytes. Newline characters found at block boundaries will be ignored.

Parameters:

encodedString - The string to decode.

Returns:

The decoded byte array.

encode

public static String encode(byte[] bytes,
                            boolean newlines)

Encodes an entire byte array into a Base64 string, with optional newlines after every 76 characters.

Parameters:

bytes - The byte array to encode.

newlines - Indicates whether or not newlines are desired.

Returns:

The encoded string.

encode

public static String encode(byte[] bytes,
                            int off,
                            int len,
                            boolean newlines)

Encodes specified bytes into a Base64 string, with optional newlines after every 76 characters.

Parameters:

bytes - The byte array to encode.

off - The starting offset.

len - The number of bytes to encode.

newlines - Indicates whether or not newlines are desired.

Returns:

The encoded string.

encode

public static String encode(char[] chars,
                            boolean newlines)

Encodes an entire chars array into a Base64 string, with optional newlines after every 76 characters.

Parameters:

chars - The characters array to encode.

newlines - Indicates whether or not newlines are desired.

Returns:

The encoded string.

encode

public static String encode(char[] chars,
                            String charset,
                            boolean newlines)

Encodes an entire chars array into a Base64 string, with optional newlines after every 76 characters.

Parameters:

chars - The characters array to encode.

charset - The character set to use for the character to byte conversion.

newlines - Indicates whether or not newlines are desired.

Returns:

The encoded string.
