(Advanced) What other users have additional rights to edit this badge entry? Currently: []



  • Public version-controlled source repository


    The project MUST have a version-controlled source repository that is publicly readable and has a URL. [repo_public]

    Source code is available at https://codeberg.org/odkr/sievemgr (primary) and https://notabug.org/odkr/sievemgr (secondary), both of which support the Git version control system and are publicly readable.



    The project's source repository MUST track what changes were made, who made the changes, and when the changes were made. [repo_track]


    To enable collaborative review, the project's source repository MUST include interim versions for review between releases; it MUST NOT include only final releases. [repo_interim]

    SieveManager follows the Git Flow branching model. Interim versions can be found in the devel branch, pre-release versions in the respective release branches.



    It is SUGGESTED that common distributed version control software be used (e.g., git) for the project's source repository. [repo_distributed]

    Git is used.


  • Unique version numbering


    The project results MUST have a unique version identifier for each release intended to be used by users. [version_unique]


    It is SUGGESTED that the Semantic Versioning (SemVer) or Calendar Versioning (CalVer) version numbering format be used for releases. It is SUGGESTED that those who use CalVer include a micro level value. [version_semver]


    It is SUGGESTED that projects identify each release within their version control system. For example, it is SUGGESTED that those using git identify each release using git tags. [version_tags]

    SieveManager follows the Git Flow branching model. Each release has its own branch. Finalized releases are tagged v<version> (e.g., v0.7.4) in the main branch.


  • Release notes


    The project MUST provide, in each release, release notes that are a human-readable summary of major changes in that release to help users determine if they should upgrade and what the upgrade impact will be. The release notes MUST NOT be the raw output of a version control log (e.g., the "git log" command results are not release notes). Projects whose results are not intended for reuse in multiple locations (such as the software for a single website or service) AND employ continuous delivery MAY select "N/A". (URL required) [release_notes]

    A human-readable change log is available at https://odkr.codeberg.page/sievemgr/changelog.



    The release notes MUST identify every publicly known run-time vulnerability fixed in this release that already had a CVE assignment or similar when the release was created. This criterion may be marked as not applicable (N/A) if users typically cannot practically update the software themselves (e.g., as is often true for kernel updates). This criterion applies only to the project results, not to its dependencies. If there are no release notes or there have been no publicly known vulnerabilities, choose N/A. [release_notes_vulns]

  • Bug-reporting process


    The project MUST provide a process for users to submit bug reports (e.g., using an issue tracker or a mailing list). (URL required) [report_process]

    Bugs can be reported using an issue tracker on GitHub and by email.



    The project SHOULD use an issue tracker for tracking individual issues. [report_tracker]

    Bugs can be reported using an issue tracker on GitHub. Bugs reported by email are posted on the issue tracker.



    The project MUST acknowledge a majority of bug reports submitted in the last 2-12 months (inclusive); the response need not include a fix. [report_responses]


    The project SHOULD respond to a majority (>50%) of enhancement requests in the last 2-12 months (inclusive). [enhancement_responses]


    The project MUST have a publicly available archive for reports and responses for later searching. (URL required) [report_archive]

    The issue tracker on GitHub includes an archive.


  • Vulnerability report process


    The project MUST publish the process for reporting vulnerabilities on the project site. (URL required) [vulnerability_report_process]

    How vulnerabilities should be reported is detailed on https://odkr.codeberg.page/sievemgr/security.



    If private vulnerability reports are supported, the project MUST include how to send the information in a way that is kept private. (URL required) [vulnerability_report_private]

    People are asked to encrypt reports with GnuPG on https://odkr.codeberg.page/sievemgr/security.



    The project's initial response time for any vulnerability report received in the last 6 months MUST be less than or equal to 14 days. [vulnerability_report_response]

  • Working build system


    If the software produced by the project requires building for use, the project MUST provide a working build system that can automatically rebuild the software from source code. [build]


    It is SUGGESTED that common tools be used for building the software. [build_common_tools]


    The project SHOULD be buildable using only FLOSS tools. [build_floss_tools]

  • Automated test suite


    The project MUST use at least one automated test suite that is publicly released as FLOSS (this test suite may be maintained as a separate FLOSS project). The project MUST clearly show or document how to run the test suite(s) (e.g., via a continuous integration (CI) script or via documentation in files such as BUILD.md, README.md, or CONTRIBUTING.md). [test]


    A test suite SHOULD be invocable in a standard way for that language. [test_invocation]

    The test suite can be invoked by python3 -munittest discover, which is standard.



    It is SUGGESTED that the test suite cover most (or ideally all) the code branches, input fields, and functionality. [test_most]


    It is SUGGESTED that the project implement continuous integration (where new or changed code is frequently integrated into a central code repository and automated tests are run on the result). [test_continuous_integration]

    SieveManager is hosted on Codeberg, which has limited resources for continuous integration (CI). Since SieveManager clocks in at less than 3k lines of code and has but one maintainer, using Codeberg's limited CI resources would be unjustified. Git hooks and Make prerequisites are used to run linters, static code analysis tools, and the test suite before each commit, push, or release.


  • New functionality testing


    The project MUST have a general policy (formal or not) that as major new functionality is added to the software produced by the project, tests of that functionality should be added to an automated test suite. [test_policy]

    The project MUST have evidence that the test_policy for adding tests has been adhered to in the most recent major changes to the software produced by the project. [tests_are_added]

    Technically true, there have been no major changes since the test suite and the test policy were added. The test suite still has a lot of catching up to do though.



    It is SUGGESTED that this policy on adding tests (see test_policy) be documented in the instructions for change proposals. [tests_documented_added]

    Contributors are asked to write tests for their contributions on https://odkr.codeberg.page/sievemgr/contrib.


  • Warning flags


    The project MUST enable one or more compiler warning flags, a "safe" language mode, or use a separate "linter" tool to look for code quality errors or common simple mistakes, if there is at least one FLOSS tool that can implement this criterion in the selected language. [warnings]

    SieveManager is analysed with:



    The project MUST address warnings. [warnings_fixed]

    Code with unaddressed warnings is neither committed, nor pushed, nor released. Git hooks and Make prerequisites are used to ensure this.



    It is SUGGESTED that projects be maximally strict with warnings in the software produced by the project, where practical. [warnings_strict]

  • Secure development knowledge


    The project MUST have at least one primary developer who knows how to design secure software. (See ‘details’ for the exact requirements.) [know_secure_design]


    At least one of the project's primary developers MUST know of common kinds of errors that lead to vulnerabilities in this kind of software, as well as at least one method to counter or mitigate each of them. [know_common_errors]

  • Use basic good cryptographic practices

    Note that some software does not need to use cryptographic mechanisms. If your project produces software that (1) includes, activates, or enables encryption functionality, and (2) might be released from the United States (US) to outside the US or to a non-US-citizen, you may be legally required to take a few extra steps. Typically this just involves sending an email. For more information, see the encryption section of Understanding Open Source Technology & US Export Controls.

    The software produced by the project MUST use, by default, only cryptographic protocols and algorithms that are publicly published and reviewed by experts (if cryptographic protocols and algorithms are used). [crypto_published]

    SieveManager secures connections with TLS by default and uses prefers secure password authentication mechanisms (SCRAM) over less secure ones if the server supports them.



    If the software produced by the project is an application or library, and its primary purpose is not to implement cryptography, then it SHOULD only call on software specifically designed to implement cryptographic functions; it SHOULD NOT re-implement its own. [crypto_call]


    All functionality in the software produced by the project that depends on cryptography MUST be implementable using FLOSS. [crypto_floss]


    The security mechanisms within the software produced by the project MUST use default keylengths that at least meet the NIST minimum requirements through the year 2030 (as stated in 2012). It MUST be possible to configure the software so that smaller keylengths are completely disabled. [crypto_keylength]

    TLS key lengths and hash iterations and SCRAM has iterations are beyond the control of SieveManager. SCRAM nonces are 144 bit.



    The default security mechanisms within the software produced by the project MUST NOT depend on broken cryptographic algorithms (e.g., MD4, MD5, single DES, RC4, Dual_EC_DRBG), or use cipher modes that are inappropriate to the context, unless they are necessary to implement an interoperable protocol (where the protocol implemented is the most recent version of that standard broadly supported by the network ecosystem, that ecosystem requires the use of such an algorithm or mode, and that ecosystem does not offer any more secure alternative). The documentation MUST describe any relevant security risks and any known mitigations if these broken algorithms or modes are necessary for an interoperable protocol. [crypto_working]

    Connections are secured with TLS v1.2+ by default and ManageSieve servers should reject attempts to authenticate using plaintext passwords over an insecure connection. SieveManager does support CRAM-MD5 and SCRAM-SHA-1 authentication, but CRAM-MD5 must be enabled by the user and is marked as obsolete in the documentation, and SCRAM-SHA-1 is mandated by RFC 5804 and only used if neither SCRAM-SHA-2 nor SCRAM-SHA-3 is supported by the server. Disabling TLS or OCSP is warned against in the documentation.



    The default security mechanisms within the software produced by the project SHOULD NOT depend on cryptographic algorithms or modes with known serious weaknesses (e.g., the SHA-1 cryptographic hash algorithm or the CBC mode in SSH). [crypto_weaknesses]

    Support for SCRAM-SHA-1 is mandated by RFC 5804. But connections are secured with TLS by default, so the use of SHA-1 should not be problematic. Also, SCRAM-SHA-1 is only used if the server supports neither SCRAM-SHA-2 nor SCRAM-SHA-3, and SCRAM-SHA-1 is still preferable to plaintext authentication.



    The security mechanisms within the software produced by the project SHOULD implement perfect forward secrecy for key agreement protocols so a session key derived from a set of long-term keys cannot be compromised if one of the long-term keys is compromised in the future. [crypto_pfs]

    SieveManager is a client and leaves the choice of the cipher suite to the server.



    If the software produced by the project causes the storing of passwords for authentication of external users, the passwords MUST be stored as iterated hashes with a per-user salt by using a key stretching (iterated) algorithm (e.g., Argon2id, Bcrypt, Scrypt, or PBKDF2). See also OWASP Password Storage Cheat Sheet. [crypto_password_storage]


    The security mechanisms within the software produced by the project MUST generate all cryptographic keys and nonces using a cryptographically secure random number generator, and MUST NOT do so using generators that are cryptographically insecure. [crypto_random]

  • Secured delivery against man-in-the-middle (MITM) attacks


    The project MUST use a delivery mechanism that counters MITM attacks. Using https or ssh+scp is acceptable. [delivery_mitm]

    SieveManager is distributed via Codeberg and the Python Package Index, both of which support HTTPS. Users may also download a GnuPG-signed tarball from Codeberg.



    A cryptographic hash (e.g., a sha1sum) MUST NOT be retrieved over http and used without checking for a cryptographic signature. [delivery_unsigned]

  • Publicly known vulnerabilities fixed


    There MUST be no unpatched vulnerabilities of medium or higher severity that have been publicly known for more than 60 days. [vulnerabilities_fixed_60_days]


    Projects SHOULD fix all critical vulnerabilities rapidly after they are reported. [vulnerabilities_critical_fixed]

  • Other security issues


    The public repositories MUST NOT leak a valid private credential (e.g., a working password or private key) that is intended to limit public access. [no_leaked_credentials]

  • Static code analysis


    At least one static code analysis tool (beyond compiler warnings and "safe" language modes) MUST be applied to any proposed major production release of the software before its release, if there is at least one FLOSS tool that implements this criterion in the selected language. [static_analysis]

    Linters and static code analysis tools are automatically run before each release.



    It is SUGGESTED that at least one of the static analysis tools used for the static_analysis criterion include rules or approaches to look for common vulnerabilities in the analyzed language or environment. [static_analysis_common_vulnerabilities]

    Bandit and Dlint include such rules.



    All medium and higher severity exploitable vulnerabilities discovered with static code analysis MUST be fixed in a timely way after they are confirmed. [static_analysis_fixed]

    No vulnerabilities have been discovered so far. Code that contains vulnerabilities that can be discovered by static code analysis should be caught by the project's Git hooks and Make prerequisites before it is pushed to a repository, let alone released.



    It is SUGGESTED that static source code analysis occur on every commit or at least daily. [static_analysis_often]

    Git hooks are used to run MyPy and Bandit on each commit. Dlint is run on each push.


  • Dynamic code analysis


    It is SUGGESTED that at least one dynamic analysis tool be applied to any proposed major production release of the software before its release. [dynamic_analysis]


    It is SUGGESTED that if the software produced by the project includes software written using a memory-unsafe language (e.g., C or C++), then at least one dynamic tool (e.g., a fuzzer or web application scanner) be routinely used in combination with a mechanism to detect memory safety problems such as buffer overwrites. If the project does not produce software written in a memory-unsafe language, choose "not applicable" (N/A). [dynamic_analysis_unsafe]

    Python is a memory-safe language.



    It is SUGGESTED that the project use a configuration for at least some dynamic analysis (such as testing or fuzzing) which enables many assertions. In many cases these assertions should not be enabled in production builds. [dynamic_analysis_enable_assertions]


    All medium and higher severity exploitable vulnerabilities discovered with dynamic code analysis MUST be fixed in a timely way after they are confirmed. [dynamic_analysis_fixed]
