Method Detail

encode

public static final byte[] encode(byte[] src)

Encode the given byte[].

Parameters:

src - the source string.

Returns:

the base64-encoded data.

encode

public static final byte[] encode(byte[] src,
                                  int lineFeed)

Encode the given byte[].

Parameters:

src - the source string.

lineFeed - a linefeed is added after linefeed characters; must be dividable by four; 0 means no linefeeds

Returns:

the base64-encoded data.

encode

public static final String encode(String src)

Encode the given string.

Parameters:

src - the source string.

Returns:

the base64-encoded string.

decode

public static final byte[] decode(byte[] src)
                           throws IllegalArgumentException

Decode the given byte[].

Parameters:

src - the base64-encoded data.

Returns:

the decoded data.

Throws:

IllegalArgumentException - Thrown if the base 64 strings contains non-valid characters, beside the bas64 chars, LF, CR, tab and space are accepted.

decode

public static final String decode(String src)

Decode the given string.

Parameters:

src - the base64-encoded string.

Returns:

the decoded string.
