It would be nice, if there would be an installer package available. Preferably it would be distributed via https://chocolatey.org/

Currently, it does as this:

0129:    |  |        |  00 de 9d d7 ea 57 18 49  a1 5b eb d7 5f 48 86 ea
0139:    |  |        |  be dd ff e4 ef 67 1c f4  65 68 b3 57 71 a0 5e 77
<...>

Instead, it should be this:

0129:    |  |        |  00
012a:    |  |        |  de 9d d7 ea 57 18 49 a1  5b eb d7 5f 48 86 ea be
013a:    |  |        |  dd ff e4 ef 67 1c f4 65  68 b3 57 71 a0 5e 77 bb

Hi,
Using W10 and VS 2019 to generate Asn1Editor:

• a click on Help->About or Help->License crashes the app

Is there a configuration issue on my side (missing/incorrect path)?

AK

This happens when current user doesn't have write permissions to write into EULA.rtf file.

The scenario is valid, the problem is that application mistakenly tries to open the file in write mode, instead of read-only mode.

It would be nice, if the open file dialog would be filtered for readable file endings.

It would be nice if the asn1editor would check for a OID.txt file in %UserProfile%\AppData\Roaming\Asn1Editor\OID.txt and use the one next to the exe as fallback.

040629170620Z UTC Time is decoded to 29.06.2004 08:06:20 which isn't correct. Hour value must be 17 (assuming 24h). Maybe it is related to underlying ASN library.

For example:

00e1:    |  |           47 6f 20 44 61 64 64 79  20 43 6c 61 73 73 20 32  ; Go Daddy Class 2
00f1:    |  |           20 43 65 72 74 69 66 69  63 61 74 69 6f 6e 20 41   ; Certification A
0101:    |  |           75 74 68 6f 72 69 74 79                           ; uthority

has extra space before semicolon, but should be after semicolon:

00e1:    |  |           47 6f 20 44 61 64 64 79  20 43 6c 61 73 73 20 32  ; Go Daddy Class 2
00f1:    |  |           20 43 65 72 74 69 66 69  63 61 74 69 6f 6e 20 41  ;  Certification A
0101:    |  |           75 74 68 6f 72 69 74 79                           ; uthority

Would you be willing to provide an msi-based installer? I'd love to install asn1editor as a winget package, but this only works with msi installern, not with zip-files.

Hi,
I am trying to use your tool to decode some base64 CMS structure (from an S/MIME message). I am using the Data Converter tool of the asn.1 Editor but it does not decode showing an error of "The given key was not present in the dictionary."
This online decoder https://lapo.it/asn1js and and openssl do not seem to have an issue with it.
Also I am able to decode CMS structures from other messages, any idea as to what may be causing the error?

A small usability improvement would be to let the user right-click on an object identifier and give it a human-readable alias.

This would make it easier to orient oneself within the data structure.

Perhaps the program could load these from a CSV file located in a particular place - this way the feature could work without having to make any changes in the GUI. Thus, everyone could maintain their own library of proprietary OIDs or share the list within a working group.

The second octet of the tag is interpreted as a length, which leads to a incomplete display of the file and wrong parsing of the contents.

Example file

If bits 1-5 are all 1 in the first octet, there are 1 or more octets possible encoding the tag number. The MSB in all of these octets is set to 1 except 0 for the last octet of the tag number.

不能正常解析，报错如上图。其他工具可以解析，文件格式没有问题。

Nice tool. However it is surprising to see that outbound connections to two different IP addresses are attempted each time upon opening the file to be analysed or edited. I write here "are attempted" as in my particular case these connection attempts were blocked and reported by firewall.

Does the tool really need to connect anywhere for its proper operation?
To me it does not look so ... So what are these connection attempts intended for?

It would be helpful, if the SAN extension wouldn't be shown as HEX but as ASCII strings:

A dark theme would be nice.

Data converter supports only certificate, certficate request and CRL in PEM form.

The data converter could also support "unknown" PEM headers, for example public sobject key info, RSA private key, CMS...

When I click edit to create a new node when I am not debugging, it will crash directly, but there is nothing in the debugging state, and there are editing nodes, and it will also crash in the debugging state.

I would be happier if the software allowed me to type in a custom font size, rather than limit me to a choice among the predefined options. Currently 16 is the maximum, but it would be even more comfortable for my eyes if I could go beyond that.

At work I often need to compare some "PKCS" files.

It would be very helpful to have a tool that can make diff ASN1 tree structure and values.

It would be great, if the tool could parse SCT log entries as described here: https://letsencrypt.org/2018/04/04/sct-encoding.html . Probably doing so has the same problems as solving this issue #5 ?

Usually I really like a tool that is translated from English to German. But with the translated OID descriptions it is really hard to google them, because nobody except of Microsofts uses them. Therefore I think it would be great, if you could just use the English labels.

What if I want to paste text directly instead of opening a file? If the software cannot paste text directly, can this function be added?

I updated the OID.txt to include the OID for signedCertificateTimestampList. As soon as you have accepted the PR for #7 I will create a new one for RufusJWB@aeb17f0 . Sadly I can't create this one before you have accepted the first PR.
