Hi, I'm using jasn.1 compiler and while trying to decompile one of the asn files I got error saying:
Exception in thread "main" java.lang.IllegalStateException: Type definition "IA5STRING" was not found in module
Could you please tell me when this type will be supported?

Hi @sfeuerhahn

I recently updated to the latest version of the JASN.1 library 1.10.0 and I see that a new BerType interface has been added so first of all I would like to thank you for considering it and adding it.

I see the BerType has been added to all types in the type hierarchy and includes the encode/decode methods.

To expand a little on my use case, in order to integrate with a legacy asn.1 message using my RPC framework, I need to be able to use the encode(Inputstream, boolean) variant in order to encode without prepending the tag.

I currently work around this by weaving in my own interface called BerSerializable, into the classes generated by the JASN.1 compiler. I use aspectj to do this at the moment but I would really like to remove it.

Would it be possible to add another interface like BerSerializable that extends BerType but which is only applied to the generated classes produced by the JASN.1 compiler.

Thanks.

Hello,

I have a use case where I need that the class's of asn1 generated by the tool don't look to the asn1 constraints when decoding, but in actual version that is not possible.

Resuming, I can't disable the constraints evaluation on the classes generated.

I think this would be a very important and useful feature, since the asn1 protocol its a very old protocol and have some constraints that in the nowadays don't make much sense.

Can someone know any workaround, for my use case.

Thank you very much

I'm using the jAsn1 library to convert ASN1 definition into java classes and then ASN1 values files (representation of the ASN1 definition with real values written in ASN1) to instantiate dynamically the java objects.
During the parsing of the ASN1 values files with jAsn1, I found, if I'm not wrong, that the empty octet string (ie in ASN1: varName ''H ) was not correctly parsed in the ASNLexer class.

Example of definition:

MyElement ::= CHOICE {
	element ElementType
}

ElementType ::= SEQUENCE {
	eltOctetString OCTET STRING,
	eltOctetStringEmpty OCTET STRING
}

With corresponding Value used:

test MyElement ::= element : {
	eltOctetString 'ABBA'H,
	eltOctetStringEmpty ''H
}

Error reported by jAsn1:

line 1:20: unexpected token: element
line 2:24: unexpected token: 'ABBA'H
line 2:31: expecting ASSIGN_OP, found ','
line 3:29: unexpected token: '
line 4:1: expecting ASSIGN_OP, found '}'

To correct this, I modified the nextToken() method by adding in the default case of the switch a new else if :

else if ((LA(1) == '\'') && (LA(2) == '\'') && (LA(3) == 'H')) {
    mH_STRING(true);
    theRetToken = _returnToken;
}

and I modified the mH_STRING method by modifying the if (_cnt73 >= 1) into if (_cnt73 >= 0).

Would it be possible that you confirm me that these changes make sens for you ?

lets cite ITU-T X.690-2021 aka ISO/IEC 8825-1:2021 (E):

8.23.5 For restricted character strings apart from UniversalString, UTF8String and BMPString, the octet string shall
contain the octets specified in ISO/IEC 2022 for encodings in an 8-bit environment, using the escape sequence and character
codings registered in accordance with ISO/IEC 2375.

which in java translates to US-ASCII or for more tolerance the ISO-8859-1 charset

8.23.7 For the UniversalString type, the octet string shall contain the octets specified in ISO/IEC 10646, using the 4-
octet canonical form (see 13.2 of ISO/IEC 10646). Signatures shall not be used. Control functions may be used provided they
satisfy the restrictions imposed by 8.23.9.

which in java translates to UTF-32 or rather transformed from UCS-4

8.23.8 For the BMPString type, the octet string shall contain the octets specified in ISO/IEC 10646, using the 2-octet BMP
form (see 13.1 of ISO/IEC 10646). Signatures shall not be used. Control functions may be used provided they satisfy the
restrictions imposed by 8.23.9.

which in java translates to UTF-16 or rather transformed from UCS-2

Hello,

Are there any plans for supporting PER encoding/decoding ?

Kind regards,

I have an asn.1 with extension marker (...)

Info ::= SEQUENCE {
   version Version,
   ...
}
Version ::= INTEGER

I got an error 'Unexpected end of sequence' when decoding data with some field/value after version.

When trying to parse cryptographic message syntax (https://tools.ietf.org/html/rfc3852) I'm unable to parse the actual content at places where the ANY type is used. Instead I only get the raw bytes.

A simplified example looks like this:

CMS DEFINITIONS IMPLICIT TAGS ::=
BEGIN
  ContentInfo ::= SEQUENCE {
        contentType ContentType,
        content [0] EXPLICIT ANY DEFINED BY contentType }
		
  ContentType ::= OBJECT IDENTIFIER
  
  id-signedData OBJECT IDENTIFIER ::= { iso(1) member-body(2)
         us(840) rsadsi(113549) pkcs(1) pkcs7(7) 2 }
  
  SignedData ::= SEQUENCE {
        version CMSVersion,
        ... }
		
  CMSVersion ::= INTEGER
        { v0(0), v1(1), v2(2), v3(3), v4(4), v5(5) }
END

When trying to replace ANY with the actual expected type such as in

CMS DEFINITIONS IMPLICIT TAGS ::=
BEGIN
  ContentInfo ::= SEQUENCE {
        contentType ContentType,
        content [0] EXPLICIT SignedData }
		
  ContentType ::= OBJECT IDENTIFIER
  
  id-signedData OBJECT IDENTIFIER ::= { iso(1) member-body(2)
         us(840) rsadsi(113549) pkcs(1) pkcs7(7) 2 }
  
  SignedData ::= SEQUENCE {
        version CMSVersion,
        ... }
		
  CMSVersion ::= INTEGER
        { v0(0), v1(1), v2(2), v3(3), v4(4), v5(5) }	
END

I receive an exception during decoding: java.io.IOException: Unexpected end of sequence, length tag: 20949315, actual sequence length: 3

the code:

Distance::= SEQUENCE {
	value	INTEGER(1..16384),

Hi,
would you mind please let me know that I can use jasn1 for decoding TAP file 3.12?
Does TAP specification exist in JASN.1?

The following asn.1 sequence taken from CCSDS SLE FSP spec (https://public.ccsds.org/Pubs/912x3b3.pdf) will produce a class ApidList that has embedded statically another class called also ApidList. The result will not compile.

ApidList ::= CHOICE
{ any [0] NULL
, apidList [1] SEQUENCE SIZE (1 .. 2048) OF Apid
}

I have generated the Java classes using the ASN schema file, and using the top level class I can successfully decode the file, however it only decode one record, and the data file is around 10-20MB in size so I'm sure it has more than one record, so my question is how do I loop through all the records in the data file using the top level java object.

ex:
my code is similar to this

File inputFile = new File("c:\\path\\to\\CDR-file");
FileInputStream is = new FileInputStream(inputFile);

CallDataRecord cdr = new CallDataRecord();
cdr.decode(is);

Above code gives me the very first record CallDataRecord but how do I traverse the rest of the CallDataRecord colleciton.

Thank you

Hello.

For example:

IA5String SIZE(0..10) would check if the length of string is between 0 and 10.
IA5String SIZE(10) would check if the length of string is exactly 10.
INTEGER(0..10) would check if the value is between 0 and 10.
INTEGER(10) would check if the value is exactly 10.

Now, my issue is what would happen if it fails? We will most likely know it as runtime, right? Would it be possible to catch this constraint error as an user of the library? If not, then I really have no idea how one would handle the bounds check errors besides just simply crashing. In any case, it should definitely should be possible to do this, just throw an error in the generated Java code in the decode method, so when the user of the library attempts to decode data that fits the specification but say, a value is higher than N, then it should throw a range error or something.

Easy-to-digest information about it here: https://stackoverflow.com/a/24238356/15088101

While we are at it, type checking would be pretty cool, too. :)

Hi,
While running fuzz testing (with afl and Kelinci) on the jasn1 generated java classes for PKIX1Explicit88.asn (ftp://ftp3.itu.int/t/fl/ietf/rfc/rfc3280/PKIX1Explicit88.html), crashes were discovered in five different locations during certificate decoding.

This was the Driver class used for the fuzzing:

import pkix1explicit88.Certificate;
import java.io.*;

public class Driver {
public static void main (String[] args) {
if (args.length != 1) {
System.err.println("driver: usage: driver file");
System.exit(1);
}
FileInputStream fis = null;
try {
fis = new FileInputStream(args[0]);
} catch (FileNotFoundException e) {
System.err.println("FileNotFound: " + args[0]);
System.exit(1);
}
try {
Certificate c = new Certificate();
c.decode(fis);
} catch (IOException e) {
System.err.println(e);
}
try {
fis.close();
} catch (IOException e) {
}
}
}

Hello, I'm using jasn1 to generate a java model from an ASN.1 defintion.
Would it be possible to generate a Java Enum in cases like that?

StationType ::= INTEGER {unknown(0), pedestrian(1), cyclist(2),
moped(3), motorcycle(4), passengerCar(5), bus(6), lightTruck(7),
heavyTruck(8), trailer(9), specialVehicles(10), tram(11),
roadSideUnit(15)} (0..255)

Thanks!

Compilation of h235.asn leads to errors while handling user-defined constraints used in SIGNED, ENCRYPTED and HASHED definitions.

User-defined constraints are explained in X.682 (look at chapter 9)

Example of user-defined constraint:

HASHED{ToBeHashed} ::= SEQUENCE {
  algorithmOID  OBJECT IDENTIFIER,
  paramS        Params, -- any "runtime" parameters
  hash          BIT STRING
}(CONSTRAINED BY { -- Hash --ToBeHashed})

Using the asn1bean-compiler on this asn file generates a .java file that does not compile:

TEST
DEFINITIONS IMPLICIT TAGS       ::=

BEGIN

ContentInfo  ::= SEQUENCE
{
     extensionType		[0]	INTEGER,
     length			[1]	INTEGER
}

END

It generates this (lines 118-128):

		if (berTag.equals(BerTag.CONTEXT_CLASS, BerTag.PRIMITIVE, 1)) {
			length = new BerInteger();
			vByteCount += length.decode(is, false);
			if (lengthVal >= 0 && vByteCount == lengthVal) {
				return tlByteCount + vByteCount;
			}
			vByteCount += berTag.decode(is);
		}
		else {
			throw new IOException("Tag does not match mandatory sequence component.");
		}

And the problem is obviously that a BerInteger is assigned to the local length variable of type BerLength. A trivial fix could be adding this.-prefix to class variable assignments.

I encode the data ( esim profile )"
{ createFCP : { fileDescriptor '4121'H, fileID '6fc4'H, lcsi '05'H, securityAttributesReferenced '03'H, efFileSize '64'H, shortEFID ''H }
" but shortEFID ''H I don't know how to do using jasn1 because shortEFID ''H has length zero without value.

The current LICENSE.txt contains the "templated" Apache 2.0 text, still with unreplaced "[yyyy] [name of copyright owner]" and the "APPENDIX: How to apply the Apache License to your work". Can you fix that ?

Furthermore, the User Guide at https://www.beanit.com/asn1/user-guide/ states "The generated Java classes may be put under a license of your choice". This exception relating to the Derivative Work should also be stated in the LICENSE.txt for clarity and comprehensiveness.

Running the compiler script in GIT bash prints the error
Error: Could not find or load main class com.beanit.jasn1.compiler.Compiler

Replacing line 8 in jasn1-compiler with SCRIPT_HOME="$( cd "$(dirname "$0")" ; pwd -P )" seems to fix the issue.

I am trying out jASN1 to convert non-streaming DER-encoded data to Java classes generated using an ASN.1-schema.

The current API has no features to sanity check the buffer allocation which can lead to memory exhaustion due to eagerly overallocating byte buffers.

Are you interested in modifying the API to specifify an upper limit to sanity check these kinds of length?

Example:

import com.beanit.jasn1.ber.types.BerOctetString;
import org.junit.Assert;
import org.junit.Test;

import java.io.ByteArrayInputStream;
import java.io.EOFException;
import java.io.IOException;

public class BerOctetStringTest {

    @Test
    public void test() throws IOException {
        BerOctetString reverseMalformed = new BerOctetString();
        try {
            byte[] malformed = {4, -124, 8, 0, 0, 0};
            reverseMalformed.decode(new ByteArrayInputStream(malformed));
            Assert.fail();
        } catch (EOFException cause) {
            // expected
        } finally {
            // buffer was already allocated
            Assert.assertEquals(134217728, reverseMalformed.value.length);
        }
    }
}`

Comment lines currently break the parser. This snippet for example

-----------------------------------------------------------------
-- Detail Output Record

will give an error like this:

When i compile an asn.1 like this:
PDU ::= CHOICE { a A, b B }

i want a choiceId in the generated class, so that i can process it with switch/case. And constants CHOICE_ID_A, CHOICE_ID_B like this:

public class PDU implements Serializable
{
    public static final int CHOICE_ID_A = 0;

    public static final int CHOICE_ID_B = 1;

    private int choiceId;

    private A a = null;

    private B b = null;
}

This snippet gives an error:

DayOfMonth ::= INTEGER (-1|1..31)

This is the error:

line 910:27: expecting R_PAREN, found '|'
line 910:28: expecting "END", found '1'
line 912:11: unexpected token: ::=

(-1|1) for example does work, while (1..31|-1) still gives an error.

I have following type definition:

XYZ02AccessControl ::= --xyzcc isPdu:"TRUE" -- EXTERNAL

which is causing this error:

AFAIK this ASN1 file used to be compiled with binary notes compiler without any problems.
How can I make it work with JASN1?

JASN1 compiler version : 1.8.1

Instead of having method signature as below;
public int encode(BerByteArrayOutputStream os) throws IOException
I would suggest having the signature like
public int encode(OutputStream os) throws IOException
This style would be more abstract and for example i would not need such import dependency in my camel-asn1 compiler where this would enable for third party developer's like me to have more loosly-coupled dependency in component library because i would not have such import

See;
https://github.com/onders86/camel/blob/CAMEL-ASN1/components/camel-asn1/src/main/java/org/apache/camel/dataformat/asn1/ASN1DataFormat.java#L35

Thanks

When I decode my data I get all key and values correct but without CHOICE and SEQUENCE.

On versions 1.7.0 I get following decoded String

{
"asn": "CHOICE{ggsnPDPRecord: SEQUENCE{recordType: 0, servedIMSI: 22084139082042F1, ggsnAddress: CHOICE{iPBinaryAddress: CHOICE{iPBinV4Address: C0A8AC7D}}, chargingID: 1931767518, sgsnAddress: SEQUENCE OF{CHOICE{iPBinaryAddress: CHOICE{iPBinV4Address: D94F8201}}}, accessPointNameNI: gprs.swisscom.ch, pdpType: 0120, listOfTrafficVolumes: .................

Now on versions 1.9.0 I get following decoded String;

{
"asn": "ggsnPDPRecord: {\n\t\trecordType: 0,\n\t\tservedImsi: 22084139082042F1,\n\t\tggsnAddress: iPBinaryAddress: iPBinV4Address: C0A8AC7D,\n\t\tchargingId: 1931767518,\n\t\tsgsnAddress: {\n\t\t\tiPBinaryAddress: iPBinV4Address: D94F8201\n\t\t},\n\t\taccessPointNameNi: gprs.swisscom.ch,\n\t\tpdpType: 0120,\n\t\tlistOfTrafficVolumes: {\n\t\t\t{\n\t\t\t\tqosRequested: gsmQosInformation:..............

CHOICE and SEQUENCE are missing. Is there an additional step to have the proper decode?

THX for help

Hello.

I expected

foobar [3] IMPLICIT ENUMERATED { six(0), eight(1), ten(2) }

to generate something like:

public static enum Foobar {
  SIX,
  EIGHT,
  TEN
}

Some even go as far as (not very :P):

if (instance.getFoobar() != null) {
  writer.writeComponent("foobar");
  switch (instance.getFoobar()) {
    case SIX:
      writer.writeIdentifier("six");
      break;
    case EIGHT:
      writer.writeIdentifier("eight");
      break;
    case TEN:
      writer.writeIdentifier("ten");
      break;
  }
}

The following snippet is adapted from PKIX1Implicit88:

END

The following error occurs when trying to compile it:

$ ./run-scripts/jasn1-compiler -f sample.asn1

This is a part of a much bigger definition. These errors break further parsing.

I was wondering whether Jasn.1 has support for TT-BER asn data structures. Difference between TT-BER and BER is that in TT-BER blocks might have indefinite length. Jasn.1 compiler does have -il argument which should take care of this kind of data structures (even though it says that this feature is not fully developed yet), but it doesn't. please confirm whether or not this -il argument is for TT-BER. And when it will have full support for TT-BER.

Are the multi line comments with /* */ are causing problems? Sometimes also comments with -- are continued on a next line directly without any white space before..
