ASN.1 tools for Python
|
||
|
|
|
||
|
|
Whenever data structures are described in some machine and programming
|
||
|
|
language independent and unambiguous way, such specification is called
|
||
|
|
abstract syntax, by contrast with machine/language specific methods,
|
||
|
|
which are called 'concrete' or 'transfer' syntaxes.
|
||
|
|
|
||
|
|
Abstract syntaxes appear useful in networking as a tool for engineering
|
||
|
|
protocols in a clear and portable way. Moreover, once a protocol is
|
||
|
|
described in some abstract language, protocol parsers and builders
|
||
|
|
could be automatically generated for various computing
|
||
|
|
architectures/programming languages, thus saving engineers from
|
||
|
|
implementing low-level transport details by hand.
|
||
|
|
|
||
|
|
Abstract Syntax Notation One (ASN.1) is a set of ITU standards
|
||
|
|
defining particular implementation of abstract data description
|
||
|
|
language accompanied by a collection of transfer encoding methods.
|
||
|
|
Perhaps the most widely used among these data serialization methods
|
||
|
|
is Basic Encoding Rules (BER) together with its derivatives (DER and
|
||
|
|
CER), while Packed Encoding Rules (PER) aims at most compact data
|
||
|
|
representation whilst in the wire.
