Method Detail

encodeString

public static java.lang.String encodeString(java.lang.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 with the Base64 encoded data.

encode

public static char[] encode(byte[] in)
Encodes a byte array into Base64 format. No blanks or line breaks are inserted.

Parameters:
in - an array containing the data bytes to be encoded.
Returns:
A character array with 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.

Parameters:
in - an array containing the data bytes to be encoded.
iLen - number of bytes to process in in.
Returns:
A character array with the Base64 encoded data.

decodeString

public static java.lang.String decodeString(java.lang.String s)
Decodes a string from Base64 format.

Parameters:
s - a Base64 String to be decoded.
Returns:
A String containing the decoded data.
Throws:
java.lang.IllegalArgumentException - if the input is not valid Base64 encoded data.
