Class B64Code


  • @Deprecated
    public class B64Code
    extends Object
    Deprecated.
    use Base64 instead
    Fast B64 Encoder/Decoder as described in RFC 1421.

    Does not insert or interpret whitespace as described in RFC 1521. If you require this you must pre/post process your data.

    Note that in a web context the usual case is to not want linebreaks or other white space in the encoded output.

        Unlike decode(char[]), extra whitespace is ignored.

        Parameters:
        encoded - String to decode.
        charEncoding - String representing the character encoding used to map the decoded bytes into a String. If null the platforms default charset is used.
        Returns:
        String decoded byte array.
        Throws:
        UnsupportedCharsetException - if the encoding is not supported
        IllegalArgumentException - if the input is not a valid B64 encoding.

        Returns:
        byte array containing the decoded form of the input.
        Throws:

        Parameters:
        encoded - String to decode.
        Returns:
        byte array containing the decoded form of the input.
        Throws:

        Deprecated.
        Base 64 decode as described in RFC 2045.

        Unlike decode(char[]), extra whitespace is ignored.

        Parameters:
