Update auto-generated .md files Add test and tool directories (aws#1) Adding test and tools directories, with CMock submodule. CI Actions (aws#2) Add header files + default configurations (aws#3) - Add files sigv4.h and sigv4_config_defaults.h - Add public-facing API elements detailed in design doc Format Date Header for ISO8601 Compliance (aws#4) Add optional utility function to format date header returned from AWS IoT (ex. in temp tokens) for compliance with the ISO8601 format required for authentication Add unit tests for SigV4_AwsIotDateToIso8601() (aws#8) Setup proof infrastructure for CBMC (aws#7) * Add Litani and templates for CBMC * Add sample proof * Implement CBMC proof for SigV4_AwsIotDateToIso8601 * Unwind all loops such that no unwinding errors occur Change submodule to use https rather than ssh for aws-templates-for-cbmc-proofs (aws#12) * CBMC fix test (do not merge) * Change AWS templates to https instead of ssh * Revert README Update README.md and LICENSE files (aws#14) Update README.md and LICENSE files before changing repo's visibility status (to public). Add remaining doxygen + link verification checks (aws#15) Add doxygen + link verifier checks (the library-specific doxygen content will be added in a separate PR for further review). [SigV4] CBMC proof for Sigv4_awsIotdatetoISO8601 API (aws#19) * Sigv4_AWSIOtDateToISO8601 CBMC PROOF * Unit test coverage changes Add release workflow (+ revert to previous license) (aws#18) change permissions of run_cbmc_proofs.py (aws#21) [Sigv4] Doxygen content updates (aws#22) * doxygen doc update * lexicon update Update proof tools (+disable submodule cloning by default) (aws#20) This commit advances Litani to release 1.10.0, and the starter kit to the tip-of-tree. This brings the following improvements: - Profiling - Litani measures the memory usage of the CBMC safety checking and coverage checking jobs - The dashboard includes box-and-whisker diagrams for memory use per proof - The dashboard includes a graph of how many parallel jobs are running over the whole run, making it easy to choose a CI machine with enough parallelism - It is now possible to designate particular proofs as "EXPENSIVE"; Litani runs expensive proofs serially, ensuring that they do not over-consume resources like RAM. - UI improvements - Each pipeline page includes a table of contents - Each pipeline page includes a dependency graph of the pipeline - Each job on the pipeline page has a hyperlink to that job - The terminal output is now less noisy SigV4_GenerateHTTPAuthorization() API Functionality (aws#16) * Squash of outdated aws#13 commits * Hold for checks * Add definitions for sorting structures * Include parsing functions * Fix old commit error * Missing asserts * (temporarily allow warnings) * Spell check + include partial context * More updates to lexicon+doxygen * Add asserts for private func. * Move access after asserts * Clarify pointer increment * Update postfix syntax for correct operator precedence * Feedback changes only * + remove accidental duplicate Implement credential scope Implement generate credential query Validation of parameter count Solution a bit overcomplicated Squash bugs and canonical query parameters should also be sorted by value Finish canonicalize query Fix canonical URI encoding Add hash helper function Add hmac implementation Add newline chars for canonical request Finish writing of canonical request Hex-encoded hash of canonical request matches Write string to sign Fix bug Refactor writeStringToSign for complexity Allow HMAC keys to be passed through separate function calls Add code for generating signing key Fix hmac bug Generate the final signature correctly Fix bug Fix newline not being written Merge Shivangi's code Stylistic changes Link OpenSSL to the test Add unit tests attaining branch coverage of 71% Integrate Shivangi's latest changes Output authBufLen when complete Update logic when headers are precanonicalized.
