Method Detail

encode

public static String encode(String buffer)

Base64 encode the string in buffer according to RFC 2045. Default character encoding is applied to buffer.

Parameters:

buffer - TBD: Description of the incoming method parameter

Returns:

the encoded bytes

encode

public static String encode(String buffer,
                            String encoding)
                     throws UnsupportedEncodingException

Base64 encode the string in buffer according to RFC 2045 with specified character encoding.

Parameters:

buffer - to encode

encoding - to use

Returns:

the encoded bytes

Throws:

UnsupportedEncodingException

encode

public static String encode(byte[] buffer)

Base64 encode the bytes in buffer according to RFC 2045.

Parameters:

buffer - to encode

Returns:

the encoded bytes

encode

public static String encode(byte[] buffer,
                            int linelen)

Base64 encode the bytes in buffer. Insert cr+lf after linelen characters.

Parameters:

buffer - to encode

linelen - to use

Returns:

the encoded bytes

decode

public static byte[] decode(String buffer)
                     throws WcmException

Base64 decode the string in the buffer according to RFC 2045.

Parameters:

buffer - TBD: Description of the incoming method parameter

Returns:

the original bytes

Throws:

WcmException - Exception raised in failure situation

decodeString

public static String decodeString(String buffer)
                           throws WcmException

Base64 decode the string in the buffer according to RFC 2045. Convenience method when it is known the the orignal consisted of characters. Platform default charset applies!

Parameters:

buffer - TBD: Description of the incoming method parameter

Returns:

the original string

Throws:

WcmException - Exception raised in failure situation
