For example, on a 32-bit machine, a data structure containing a 16-bit value followed by a 32-bit value could have 16 bits of padding between the 16-bit value and the 32-bit value to align the 32-bit value on a 32-bit boundary.
In ANSI X9.23, between 1 and 8 bytes are always added as padding. The block is padded with random bytes (although many implementations use 00) and the last byte of the block is set to the number of bytes added. [6] Example: In the following example the block size is 8 bytes, and padding is required for 4 bytes (in hexadecimal format)
For heartbeat (HEARTBEAT), this value is always 4. Chunk flags There are currently no flags used. Chunk length This is the chunk length which has a minimum value of 8 with no parameter value added. Fixed parameters: None Optional parameters are shown with alternating background colors of green and blue: Parameter type = 1
An optional feature of IPv6, the jumbo payload option in a Hop-By-Hop Options extension header, [8] allows the exchange of packets with payloads of up to one octet less than 4 GB (2 32 − 1 = 4 294 967 295 octets), by making use of a 32-bit length field. Packets with such payloads are called jumbograms.
In order to allow some frames using Ethernet II framing and some using the original version of 802.3 framing to be used on the same Ethernet segment, EtherType values must be greater than or equal to 1536 (0x0600). That value was chosen because the maximum length of the payload field of an Ethernet 802.3 frame is 1500 octets (0x05DC).

The padded data comprises (in this order): The length of the unpadded data (in bits) expressed in big-endian binary in n bits (i.e. one cipher block); The unpadded data; As many (possibly none) bits with value 0 as are required to bring the total length to a multiple of n bits
Both the width of the rows and the permutation of the columns are usually defined by a keyword. For example, the keyword ZEBRAS is of length 6 (so the rows are of length 6), and the permutation is defined by the alphabetical order of the letters in the keyword. In this case, the order would be "6 3 2 4 1 5".
