readDEROctetString
- Throws:
SerializationException
-
readDEROctetString
- Throws:
SerializationException
-
readList
public static byte[][] readList(byte[] input, int listWidth, int elemWidth) throws SerializationException - Throws:
SerializationException
-
readList
public static byte[][] readList(InputStream input, int listWidth, int elemWidth) throws SerializationException Read a variable length vector of variable sized elements as described by RFC5246 section 4.3. The vector is prefixed by its total length, in bytes and in big endian format, so is each element contained in the vector.- Parameters:
listWidth
- the width of the vector's length field, in bytes.elemWidth
- the width of each element's length field, in bytes.- Throws:
SerializationException
- if EOF is encountered.
-
readVariableBytes
Read a length-prefixed sequence of bytes. The length must be encoded in big endian format.- Parameters:
width
- the width of the length prefix, in bytes.- Throws:
SerializationException
- if EOF is encountered, or ifwidth
is negative or greater than 4
-
readFixedBytes
Read a fixed number of bytes from the input stream.- Parameters:
length
- the number of bytes to read.- Throws:
SerializationException
- if EOF is encountered.
-
readNumber
Read a number in big endian format from the input stream. This methods only supports a width of up to 4 bytes.- Parameters:
width
- the width of the number, in bytes.- Throws:
SerializationException
- if EOF is encountered, or ifwidth
is negative or greater than 4
-
readLong
Read a number in big endian format from the input stream. This methods supports a width of up to 8 bytes.- Parameters:
width
- the width of the number, in bytes.- Throws:
SerializationException
- if EOF is encountered.IllegalArgumentException
- ifwidth
is negative or greater than 8
-
readByte
Read a single byte from the input stream.- Throws:
SerializationException
- if EOF is encountered.
-
writeVariableBytes
public static void writeVariableBytes(OutputStream output, byte[] data, int width) throws SerializationException Write length prefixed sequence of bytes to the ouput stream. The length prefix is encoded in big endian order.- Parameters:
data
- the data to be written.width
- the width of the length prefix, in bytes.- Throws:
SerializationException
- if the length ofdata
is too large to fit inwidth
bytes orwidth
is negative.
-
writeFixedBytes
Write a fixed number sequence of bytes to the ouput stream.- Parameters:
data
- the data to be written.- Throws:
SerializationException
-
writeNumber
public static void writeNumber(OutputStream output, long value, int width) throws SerializationException Write a number to the output stream. The number is encoded in big endian order.- Parameters:
value
- the value to be written.width
- the width of the encoded number, in bytes- Throws:
SerializationException
- if the number is too large to fit inwidth
bytes orwidth
is negative.
