I am new to ASN.1 coding. I am trying to create parse data from a ASN.1 format, replace values to the tag and regenerate a file in same format

what is asn.1 explain in detail
asn.1 tutorial
asn.1 decoder
asn.1 editor
asn 1 per encoding example
python-asn1
packed encoding rules
asn.1 tutorial pdf

This is my input template:

headerValue ProfileElement ::= header : { 
major-version 2, 
minor-version 0, 
profileType "GSMA Profile Package", 
iccid '89019990001234567893'H, 
eUICC-Mandatory-services { 
usim NULL, 
milenage NULL, 
javacard NULL }, 
eUICC-Mandatory-GFSTEList { 
-- see Note 1 
id-MF, 
id-USIM }, 
-- These SMS connectivity parameters may be freely changed 
connectivityParameters 'A0090607#TON_NPI#DIALING_NUMBER'H } 

I need the output file in same format but with new values for ICCID which will be generated dynamically by JAVA code

You can use jASN1 library available for java. Pass your data to it and get the parsed object list. There after, you can change the iccid value.

Abstract Syntax Notation One, I am new to ASN.1 coding. I am trying to create parse data from a ASN.1 format, replace values to the tag and regenerate a file in same format. Posted by: admin​  How to create a simple ASN.1 parser Step by step instructions to create a ASN.1 parser using asn1c. ASN.1 is a formal notation used for describing data transmitted by telecommunications protocols, regardless of language implementation and physical representation of these data, whatever the application, whether complex or very simple.

Do you need also to convert in DER coding ? If so, I would suggest to use Nokalva OSS library to create the object hierarchy in Java and then convert in DER.

If you don't need the DER coding, a simple trick we sometime use is to put a placeholder like you did in the #TON_NPI and make a search / replace with Java.

PS: of course if you update ICCID in ProfileHeader you need to update also content of 2FE2 under MF (that is actually more important)

[PDF] ASN.1 Compiler Version 7.2 C# Users Guide Reference Manual , Abstract Syntax Notation One (ASN.1) is a standard interface description language for defining The advantage is that the ASN.1 description of the data encoding is independent The PEM format is often used to encapsulate DER-​encoded ASN.1 30 — type tag indicating SEQUENCE 13 — length in octets of value that  I'm trying to make der encoder from the input data in ASN.1 and the module in ASN.1. The input data is variable and the module is constant. I successfully compiled the source file with the module and now I need to deal with the input data. This ASN.1 compiler can provide a DER encoder from BER/XER.

What you have quoted is the part of ASN.1 module definitions of embedded UICC(eUICC) Interoperable Format Technical Specification published by SIM Alliance.

After collecting all ASN.1 definitions starting from section 7.3 in a one file as module definition, it can be compiled with any free or commercial java ASN.1 compiler. Java sources generated for data types and encode/decode run-time library of ASN.1 compiler can be embedded to your application to generate ASN.1 encoded byte stream for Profile Element.

ASN.1 data types to SDL and to encode/decode ASN.1 data types. By using ASN.1 data types in the implementation of your application, you will optimize your development process. The following list dis-plays some of the advantages of ASN.1: • ASN.1 is a standardized, vendor-, platform- and language indepen-dent notation.

Simon promises to replace it with a proper tutorial. ASN.1 is a notation for describing data structures; it's very much like a type declaration in C or C++.

Asn1 editor, Data-links AsnLib Generated Header Files Returns From AsnLib Parsing Since ASN.1 does not specify content, specifications can be created as new ASN.1 also allows the specification of numerical tags (used for the binary encoding) in [] in Value notation (or data encoded in the text form of ASN.1) looks like this:. About the only time it is efficient to read the lower level ASN.1 raw values is when there are just a few types of simple values that one is interested in processing. For example, if one wanted to record the relative occurrence of journal titles in some particular ASN.1 file, one could find those without worrying about the objects.

Comments
  • What do you want to do with the result ? I'm asking that because what you show is an ASN.1 value (usually only used for specifying or documenting).
