Method Detail

clone

Object clone()
             throws CloneNotSupportedException

Throws:

CloneNotSupportedException

getEncryptionType

int getEncryptionType()

Serialize encryption info.

The encryption should consist of the following:

• version (1 byte)
• encryption type (1 byte)
• length of 'blob' (2 bytes)
• byte blob (n bytes)

Returns:

encryption type (constants defined in this class)

getSerializeSize

int getSerializeSize()

Return number of bytes required to serialize this encryption info.

Returns:

number of bytes to serialize.

serialize

byte[] serialize()

Serialize the encryption info, returning a byte buffer containing the serialized data.

Returns:

byte buffer of serialized data

serialize

int serialize(byte[] buffer,
            int pos)

Serialize the encryption info into buffer starting at position 'pos'.

Parameters:

buffer - buffer to serialize to

pos - position to start serializing

Returns:

new position into buffer
