[pyasn1-modules 0.4.8 with pyasn 0.4.8]
The following code attempts to roundtrip a certificate via the following steps:
- decode openssl-generated DER from file
- immediately encode it back out again
f = open("my_cert.der", "rb")
der = f.read()
cert, _ = decode_der(der, asn1Spec=rfc5280.Certificate())
# 'cert' contents can be examined here: e.g.: print(str(cert))
der2 = encode_der(cert, asn1Spec=rfc5280.Certificate())
^----- exception inside encode_der() here
The generated stack trace is absolutely enormous, actually containing one line that is thousands of characters long, which makes it impossible to read.
FWIW, I have similar roundtripping test-code using the asn1Specs univ.Integer() and rfc5652.ContentInfo(). Since this other code is working, especially the latter one, I suspect this issue might Certificate-oriented.
Thoughts?
Parsing certificate extensions exception in 0.2.1
Parsing certificate extensions with pyasn1 0.4.3 and modules 0.1.5 is successful but fails in 0.2.1 with:
pyasn1.error.PyAsn1Error: <TagSet object at 0x7f66f3050e80 tags 0:32:16> not in asn1Spec: <OctetString schema object at 0x7f66f28410b8 tagSet <TagSet object at 0x7f66f2861438 tags 0:0:4> encoding iso-8859-1>
dependency version pain
Instead of accepting any versions of pyasn1 >= 0.1.8 it would be worthwhile to tie that down to something you've tested with. That would have avoided the problem seen today.
rfc4055 missing *WithRSAEncryption Algorithm Identifiers
The rfc4055 module has identifiers for raw sha224 to sha512, but none for the withRSAEncryption variants.
It has the following, which is discussed in the 5th paragraph of RFC 4055 Section 5:
sha256Identifier = rfc5280.AlgorithmIdentifier()
sha256Identifier['algorithm'] = id_sha256
sha256Identifier['parameters'] = univ.Null("")
But it doesn't have, the following which is discussed in the subsequent paragraphs of Section 5 of the RFC:
sha256WithRSAEncryptionIdentifier = rfc5280.AlgorithmIdentifier()
sha256WithRSAEncryptionIdentifier['algorithm'] = sha256WithRSAEncryption
sha256WithRSAEncryptionIdentifier['parameters'] = univ.Null("")
The same goes for sha224, sha384 and sha512.
pyasn1-modules broken with pyasn1==0.1.9
The requirements.txt for pyasn1-modules 0.2.1 permits pyasn1<0.5.0. But with pyasn1==0.1.9:

ImportError: cannot import name 'opentype'Upgrading to pyasn==0.4.2 fixes the issue.
Installation error for version 0.1.2 on Python 2.7
Hi, this morning after the update to 0.1.2 I started receiving an error during pip install of a dependent library, google-api-python-client==1.6.2. I'm using Python 2.7, it's run as a clean Docker build, and there are no other dependencies.
Here's the relevant piece of the error trace:

Sad news and transfer of ownership - pyasn1 and pyasn1-modules
Unfortunately, this repo won't be maintained anymore.
With great sorrow, we have to announce that @etingof has passed away.
Please, find more information here:
https://lists.openstack.org/pipermail/openstack-discuss/2022-August/030062.html
The pyasn1 and pyasn1-modules ownership was transferred to https://github.com/pyasn1/pyasn1-modules
Please, report your issues and file pull requests there.
Thank you!
And take care.
rfc4210 cmp implicit confirm
Hi everyone,
I'm using pyasn1-modules to build a small cmp client (subset of rfc4210). I think there is a mistake in the rfc4210 module in the PKIHeader class.
The last entry should be
namedtype.OptionalNamedType(
'generalInfo', univ.SequenceOf(
componentType=rfc4210.InfoTypeAndValue().subtype(
sizeSpec=constraint.ValueSizeConstraint(1, MAX))
).subtype(explicitTag=tag.Tag(tag.tagClassContext, tag.tagFormatSimple, 8))
)instead of
namedtype.OptionalNamedType(
'generalInfo', univ.SequenceOf(
componentType=InfoTypeAndValue().subtype(
sizeSpec=constraint.ValueSizeConstraint(1, MAX),
explicitTag=tag.Tag(tag.tagClassContext, tag.tagFormatSimple, 8)
)
)Stumbled over this when I tried to use cmp implicit confirm. The top code shows how I was able to get it running with a CA-Software.
Thanks,
Alex

The ASN.1 schema for RevRepContent requires a SEQUENCE OF PKIStatusInfo. This is mentioned in the comment, but not implemented as such.
Trouble decoding IEC 61850 GOOSE PDU data
I am having trouble decoding IEC 61850 GOOSE PDU data. This data is encoded using BER. You can find the ASN.1 notation that wireshark uses here: https://github.com/boundary/wireshark/blob/master/asn1/goose/goose.asn. My repository is located on gitub: https://github.com/keith-gray-powereng/goose. The pyasn.1 classes corresponding to the ASN.1 notation live in the https://github.com/keith-gray-powereng/goose/blob/master/goose/goose_pdu.py file.
The last three tests in https://github.com/keith-gray-powereng/goose/blob/master/tests/test_goose.py are generating errors while trying to decode the data. These tests cover decoding larger pieces of the data that make use of "SEQUENCE (OF)".
One example of a failing test is as follows. The encoded_data is taken straight from a captured GOOSE packet.
from pyasn1 import debug
debug.setLogger(debug.Debug('all'))
encoded_data = (
"\xa2\x12"
"\x83\x01\x00\x84\x03\x03\x00\x00\x91\x08\x5a\xaa\xe0\xa4\x6f\xf3"
"\x5e\x92"
)
expected = False
iec61850_goose_pdu = IECGoosePDU().clone()
all_data = iec61850_goose_pdu.getComponentByName('allData')
data_item_1 = all_data.getComponentByPosition(0)
structure = data_item_1.getComponentByName('structure')
import pdb; pdb.set_trace()
decoded_data, unprocessed_trail = decoder.decode(
encoded_data,
asn1Spec=Data().clone()
)
assert expected == decoded_dataThis is expected to decode into a SEQUENCE OF a boolean, a bit-string, and a utc-time which are all members of Data.
The generated error is:

This happens with all python versions I've tested, including python3.10.2. There was no issue building v0.2.7.
[PSA] Transfer of ownership
Public Service Announcement
Ilya Etingof is currently unable to maintain pyasn1 and pyasn1-modules. PyPI package ownership for pyasn1 and pyasn1-module has been transfered to me and Simon Pichugin in PyPI support ticket #2090. The upstream repositories for pyasn1 and pyasn1-modules are now in the GitHub organization https://github.com/pyasn1/.
Please join us at https://github.com/pyasn1 if you like to help. We are looking for more contributors and maintainers to spread the workload.
I'm also looking for users to test pyasn1-0.5.0rc1 and pyasn1_modules-0.3.0rc1. You can install the pre-release from PyPI:
pip install --pre pyasn1 pyasn1-modules
pyasn1>=0.4.1 requirement
Hi!
Latest release (0.2.1) depends on pyasn1.type.opentype which has been added in version 0.4.1 of pyasn1, however the setup.py of this package doesn't explicitly depend on that version, instead any version is accepted.
I had a situation where pyasn==0.2.3 was already installed and pyasn1-modules==0.2.1 was installed as a dependency of google-cloud-storage==1.6.0. On my CI this lead to:
File "<redacted_ve>/lib/python3.6/site-packages/pyasn1_modules/rfc2459.py", line 20, in <module>
from pyasn1.type import opentype
ImportError: cannot import name 'opentype'
Fixed this by updating requirements in my project, just wanted to let you know.
Thanks!
RFC2560 ResponderID type incorrect.
It looks like the ResponderID definition used in rfc2560.py is incorrect. According to the spec (https://tools.ietf.org/html/rfc2560 appendix B), they should both be EXPLICIT tags, while the module has them as IMPLICIT tags.
how can i make pkcs#7 detached signature?
