Decodes a Base64 string.

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.

decode

public static byte[] decode(char[] in)
Decodes Base64 data. No blanks or line breaks are allowed within the Base64 encoded data.

Parameters:
in - a character array containing the Base64 encoded data.
