Method Detail

encode

public void encode(java.io.InputStream in,
                   java.io.OutputStream out)
            throws java.io.IOException

Encode binary input stream into Base64 character stream. The encoded data is written in max 76 character lines.

Parameters:

in - the InputStream to encode.

out - the OutputStream to which the encoded data is written.

Throws:

java.io.IOException - if an I/O error occurs while encoding.

encode

public void encode(java.io.InputStream in,
                   java.io.OutputStream out,
                   boolean newLines)
            throws java.io.IOException

Encode binary input stream into Base64 character stream.

Parameters:

in - the InputStream to encode.

out - the OutputStream to which the encoded data is written.

newLines - if true the encoded data is written in max 76 character lines.

Throws:

java.io.IOException - if an I/O error occurs while encoding.

encode

public java.lang.String encode(byte[] data,
                               boolean newLines)

Encode byte array into Base64 String.

Parameters:

data - the byte array to encode

newLines - if true the encoded data is written in max 76 character lines.

Returns:

String containing the resulting Base64 encoded characters

decode

public void decode(java.io.InputStream in,
                   java.io.OutputStream out)
            throws java.io.IOException

Decode Base64 input character stream into binary output stream.

Parameters:

in - the InputStream to decode.

out - the OutputStream to write the decoded data to.

Throws:

java.io.IOException - if an I/O error occurs while decoding.

decode

public java.lang.String decode(java.io.InputStream in)
                        throws java.io.IOException

Decode Base64 input characters into a String representation of decoded binary stream.

Parameters:

in - the InputStream to decode.

Returns:

String containing decoded binary stream

Throws:

java.io.IOException

decode

public byte[] decode(java.lang.String b64)
              throws java.io.IOException

Decode Base64 encoded String into byte array.

Parameters:

b64 - the string to decode

Returns:

byte array containing the decoded bytes.

Throws:

java.io.IOException
