* Remove assert statements from bignum
improve logging around bignum computation
* remove assert.h update max ballot payload
* reset max ballot payload to 2000
* Explicitly break loop on import end of file
add log.h to coordinator
* modify test selections
* Support external_ballot_identifer as a string. Export/import ballots from encrypter
Add support for encrypter to export ballots to the file system. Import encrypter ballots into coordinator. Add a hashtable implementation that tracks ballot cast/spoil state against the external identifier (ballot_collection.c). Support loading ballots into a buffer.
Fix memory leaks in bignum.c, crypto.c, decryption/coordinator.c, decryption/trustee.c, voting/coordinator.c, voting/encrypter.c, etc.
Rework the API example to demonstrate the new external id and file system changes.
Improve debug logging. Add more api documentation. Modify MAX_BALLOT_PAYLOAD to 2000. Explicitly add // TODO: to track remaining work.
Note this commit is a work in progress and currently breaks the simple example.
* Remove Simple Example, add api doc stubs
Add stubs for the api documentation. Remove the simple example and use the api sample in the PR pipeline workflow
* Fix Merge Issue
* Verify malloc success
* Address PR Feedback
* Fix LGTM alerts
* Add soft delete of encrypter files
* Free CP Proof
* Fix windows Makefile
* test fix pr workflow on windows
* use secure api's
* explicitly compile release
* flush file write before read
* clean up makefile
* Document consumers resonsible for free
when calling an api that generates a filename as an out parameter, the caller is responsible for managing the memory of the out parameter when the call is successful
* Rename static coordinators in API to differentiate local vars
add an underscore prefix to static coordinator instance handles to differentiate vars until #62 is complete
* add new enum cases to the end on voting coordinator
* Add convenience logging
* Handle error cases on file access
use convenience logging
* use consistent file formatting when rebuilding tracker string
* optimize null check
* explicitly set tracker array positions to NULL on failure
* Reformat refactor Decryption_Coordinator_receive_share
* guard tallies_initialized when freeing resources
explicitly initialize num_tallies
* rename _encrypted_ballot_count
* don't return early
* do not fail soft delete if rename fails
* fix assignment
* adjust number of ballots to force a rebuild
* Rename refactor decryption_trustee
add summary comments. Consistently format files.
* Add Trustee index to decryption trustee
* ignore files in ballots results folder
* handle announce trutees less than max trustees
* use the threshold trustees in test to decrypt with missing trustees
only tally votes using the threshold number of trustees to validate that threshold decryption works as expected
* add test_ballot. Use assert for some test conditions
check expected and actual tally results.
* fix extraneous arguments in call
* when writing files, create directories if they do not exist
* revert botched merge file
* modify tasks to include debug shared lib builds
* use FILENAME_MAX from stdio instead of PATH_MAX from linux/limits
* include header guard
* Fix windows support for mkdir
* Fix for encrypting ballot boolean arrays with multiple true selections; Repurpose Validate_selections; Update/simplify api test example with random selections
* Also remove extra Validate_selections call from simple example since its called anyway
* fix random ballots in example tests to be more random and valid ballots
* Have expected_num_selected passed in from higher level for encrypting ballot
This introduces an api layer to the C library which can be used to execute the entire election via single api methods to create election/key ceremony, encrypt ballot, register ballot, record cast/spoil ballot, and tally votes.
* Fix loop in computeTrusteePolynomial that results in segfault
* Implement API to Create Election from the C library and update simple example test
* Added missing include
* Add method to free bytes allocated for trustee states and joint public key
* Revert original simple example, create new simple example using api
* Intial implementation to encrypt ballot from C API; added new api to example
* Refactor create-election api in C to write joint key to config param; updated api example
* Update EncryptBallot API signature to work with PInvoke; updated api example
* Add API Tests to the test workflow
* Fix for EncryptBallot passing in array of selections because booleans are non-blittable from C# and the array is not a fixed size
* Implement RecordBallots and TallyVotes API in C library (Merge into PR #44) (#46)
* Implement RecordBallots API in C library
* Fix C example api tests for selection array; Refactor RecordBallot API to return the created file name
* Implement TallyVotes API and example test in C library
* Convert to using byte array for input instead of unsigned short array
