Method Detail

encode

public static int encode(byte[] binaryData,
                         int binaryOffset,
                         int length,
                         byte[] encodedData,
                         int encodedOffset)

Converts binary data into base64 encoded data.

Parameters:

binaryData - Binary data to be encoded.

binaryOffset - Offset into binaryData where to the data to be encoded begins.

length - Length of data to encode.

encodedData - Buffer receiving base64 encoded data.

encodedOffset - Offset into encodedData where the store base64 encoded data.

Returns:

Length of encoded base64 data.

decode

public static int decode(byte[] encodedData,
                         int encodedOffset,
                         int length,
                         byte[] binaryData,
                         int binaryOffset)

Converts base64 encoded data into binary data.

Parameters:

encodedData - Base64 encoded data.

encodedOffset - Offset into encodedData where the base64 encoded data starts.

length - Length of encoded data.

binaryData - Decoded (binary) data.

binaryOffset - Offset into binaryData where to store the decoded binary data.

Returns:

Length of decoded binary data.
