Method Detail

encodeString

public static String encodeString(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 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 String encodeLines(byte[] in,
                                 int iOff,
                                 int iLen,
                                 int lineLen,
                                 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 String decodeString(String s)

Decodes a string from Base64 format. No blanks or line breaks are allowed within the Base64 encoded input data.

Parameters:

s - A Base64 String to be decoded.

Returns:

A String containing the decoded data.

Throws:

IllegalArgumentException - If the input is not valid Base64 encoded data.

decodeLines

public static byte[] decodeLines(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.

Returns:

An array containing the decoded data bytes.

Throws:

IllegalArgumentException - If the input is not valid Base64 encoded data.

decode

public static byte[] decode(String s)

Decodes a byte array from Base64 format. No blanks or line breaks are allowed within the Base64 encoded input data.

Parameters:

s - A Base64 String to be decoded.

Returns:

An array containing the decoded data bytes.

Throws:

IllegalArgumentException - If the input is not valid Base64 encoded data.

decode

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