400..Netstrings.D. J. Bernstein, [email protected]. Introduct
ion.. A netstring is a self-delimiting encoding of a string. Netstri
ngs are. very easy to generate and to parse. Any string may be encod
ed as a. netstring; there are no restrictions on length or on allowe
d bytes.. Another virtue of a netstring is that it declares the stri
ng size up. front. Thus an application can check in advance whether
it has enough. space to store the entire string... Netstrings may
be used as a basic building block for reliable network. protocols. M
ost high-level protocols, in effect, transmit a sequence. of strings
; those strings may be encoded as netstrings and then. concatenated
into a sequence of characters, which in turn may be. transmitted ove
r a reliable stream protocol such as TCP... Note that netstrings can
be used recursively. The result of encoding. a sequence of strings
is a single string. A series of those encoded. strings may in turn b
e encoded into a single string. And so on... In..400.. this document
, a string of 8-bit bytes may be written in two. different forms: as
a series of hexadecimal numbers between angle. brackets, or as a se
quence of ASCII characters between double quotes.. For example, <
68 65 6c 6c 6f 20 77 6f 72 6c 64 21> is a string of. length 12; i
t is the same as the string "hello world!"... Although this document
restricts attention to strings of 8-bit bytes,. netstrings could be
used with any 6-bit-or-larger character set....2. Definition..
