Implements ChaChaPolySigil that applies pre-obfuscation before sending
data to CPU encryption routines. This ensures raw plaintext is never
passed directly to encryption functions.
Key improvements:
- XORObfuscator and ShuffleMaskObfuscator for pre-encryption transforms
- Nonce is now properly embedded in ciphertext, not stored separately
in headers (production-ready, not demo-style)
- Trix crypto integration with EncryptPayload/DecryptPayload methods
- Comprehensive test coverage following Good/Bad/Ugly pattern
Adds comprehensive docstrings and runnable examples to all public APIs in the `crypt`, `enchantrix`, and `trix` packages. This change is intended to bring the project's documentation to a production-ready standard and to provide high-quality, verifiable examples for the official Go documentation website.
This commit refactors the test suites for the `crypt` and `enchantrix` packages to follow the "Good, Bad, Ugly" testing methodology.
- `_Good` tests cover the ideal "happy path" scenarios.
- `_Bad` tests cover expected failure scenarios with well-formed but invalid inputs.
- `_Ugly` tests cover malicious or malformed inputs designed to cause crashes or panics.
This change improves test coverage and ensures that the codebase is more robust and resilient to unexpected inputs.
- Refactors sigil tests into a dedicated `sigils_test.go` file.
- Adds a comprehensive data-driven test for all hash sigils.
- Adds a test for error handling in the `HashSigil`.
- Adds a test for the `JSONSigil.Out` method.
- Adds tests for the error paths in the `GzipSigil.In` method.
- Fixes a bug in `GzipSigil.In` that was introduced while adding tests.
Moves all test files from the `tdd/` directory to their corresponding `pkg/` subdirectories. This aligns with standard Go project structure and simplifies the test coverage workflow.
- Moves `tdd/crypt/crypt_test.go` to `pkg/crypt/`
- Moves `tdd/enchantrix/enchantrix_test.go` to `pkg/enchantrix/`
- Moves `tdd/trix/trix_test.go` to `pkg/trix/`
- Simplifies the `Taskfile.yml` to use a standard `go test` command.
- Removes the now-obsolete `tdd/` directory.
- Adds generated coverage files to `.gitignore`.
This commit consolidates and enhances the tests for the `enchantrix` and `trix` packages, moving them into the `tdd/` directory to improve test coverage and organization.
- Consolidates existing tests from `pkg/enchantrix/` and `pkg/trix/` into new, more comprehensive test suites in `tdd/enchantrix/` and `tdd/trix/` respectively.
- Expands the test suites to include more "Bad" and "Ugly" scenarios.
- Deletes the original test files from `pkg/enchantrix/` and `pkg/trix/` to avoid redundancy.
- Organizes the `tdd/` directory with subdirectories for each package to prevent Go package conflicts.
This commit introduces a new `enchantrix` package that provides a flexible and powerful way to transform data using a "Sigil" interface. The package includes implementations for various encoding types (hex, base64, gzip, json) and a comprehensive set of cryptographic hash functions.
The `trix` package has been refactored to use the new `enchantrix` package, and its API has been simplified to use string identifiers for Sigils, making it easier to use and decoupling it from the implementation details of the `enchantrix` package.
All new functionality is fully tested, and the existing tests have been updated to reflect the API changes.
