It compiles ASN.1 specification files and provides encode/decode operations across eight codec standards\u2014BER, DER, PER, UPER, OER, XER, JER, and GSER\u2014allowing you to serialize Python dictionaries into binary or text formats and deserialize them back. It also includes command-line tools for converting between formats and a C source code generator for OER and UPER codecs when you need compiled performance.\n\nThe library supports a subset of the ASN.1 specification; it does not yet handle CLASS keywords, parametrization, EMBEDDED PDV, ANY types, or DURATION types. The C generator requires all types to have known maximum sizes and works only with a limited set of ASN.1 primitives. Installation is high-friction due to the source-only distribution, and maintenance is dormant\u2014the last release was 762 days ago, though the repository remains accessible.","worth_installing":"Yes, if you work with ASN.1 protocols and can tolerate high install friction and dormant maintenance. The library covers a broad range of codecs and includes useful command-line tools. No, if you need active maintenance, recent bug fixes, or support for the full ASN.1 specification\u2014consider alternatives or fork the repository if your use case is critical."},"id":"asn1tools","links":{"html":"https://skillfed.io/packages/asn1tools","md":"https://skillfed.io/packages/asn1tools.md","pypi":"https://pypi.org/project/asn1tools/"},"maintenance":{"status":"dormant"},"meta":{"latest_release":"2024-07-13","license_spdx":null,"license_treatment":"permissive","name":"asn1tools","python_support":"unspecified","summary":"ASN.1 parsing, encoding and decoding."},"popularity":{"monthly_downloads":557056,"position":6015,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.167.0"}
