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
- Add `SymmetricallyDecrypt` to `pkg/crypt/std/pgp`.
- Add validation for empty passphrases in `SymmetricallyEncrypt` and `SymmetricallyDecrypt`.
- Refactor `pkg/crypt/std/pgp/pgp.go` to use package-level variables for `openpgp` functions to enable mocking.
- Add comprehensive tests in `pkg/crypt/std/pgp/pgp_test.go` to cover error paths using mocks, achieving 100% coverage.
- Remove practically unreachable error check in `GenerateKeyPair` for `SignUserId` (as `NewEntity` guarantees validity).
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.

This commit introduces several improvements to the RSA implementation:
- Preserves zero-value service safety by lazily initializing the RSA service in `pkg/crypt/crypt.go`.
- Enforces a minimum RSA key size of 2048 bits in `pkg/crypt/std/rsa/rsa.go` to prevent the generation of insecure keys.
- Exposes the OAEP label parameter in `Encrypt` and `Decrypt` functions, allowing for more advanced use cases.
- Adds a test case to verify that `GenerateKeyPair` correctly rejects key sizes below the new minimum.
This commit introduces a fuzz test for the `Decode` function in the `trix` package. This test immediately uncovered a critical out-of-memory (OOM) vulnerability.
- Adds a new fuzz test, `FuzzDecode`, to `pkg/trix/fuzz_test.go` to continuously test the `Decode` function with a wide range of malformed inputs.
- Fixes a denial-of-service vulnerability where a malicious input could specify an extremely large header length, causing the application to crash due to an out-of-memory error.
- Introduces a `MaxHeaderSize` constant (16MB) and a check in the `Decode` function to ensure that the header length does not exceed this limit.
- Adds a new error, `ErrHeaderTooLarge`, to provide clear feedback when the header size limit is exceeded.
This commit introduces a streaming API to the `trix` package, making it more memory-efficient for large payloads.

- Includes a comprehensive set of "Good, Bad, Ugly" tests for the new streaming functionality, including tests for failing readers and writers.
This commit introduces several improvements to the `trix` package, focusing on test coverage and robustness.

- Introduces a `TestPackUnpack_Ugly` test to ensure that calling `Pack` with a `nil` payload is handled gracefully.
- Simplifies the `TestChecksum_Ugly` test by manually constructing a corrupted byte slice, making the test more direct and easier to understand.
- Adds a new "Bad" test case to verify that the `Decode` function correctly handles invalid version numbers.
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.
This commit introduces a standard RSA implementation in `pkg/crypt/std/rsa`.
The new `rsa.Service` provides a clean API for RSA operations, including:
- Key pair generation
- Encryption and decryption of data
The implementation uses the standard `crypto/rsa` package and follows best practices, including OAEP padding. The main `crypt.Service` has been updated to integrate and expose this new functionality.
This work was done to validate the build environment, and the tests for this implementation pass successfully, confirming that the previous testing issues were isolated to the OpenPGP library.
This commit introduces a full OpenPGP implementation in `pkg/crypt/std/openpgp`, using the ProtonMail `go-crypto` library.
The new `openpgp.Service` provides a clean, Web3-friendly API for PGP operations, including:
- Key pair generation
- Subkey management
- Encryption and decryption of messages
- Signing and verification of messages
The implementation is based on the user's `Core` repository and uses file-based key management. The main `crypt.Service` has been updated to integrate and expose this new functionality.
This commit enhances the Trix container with two new features for improved data integrity and flexibility:
1. **Configurable Checksums:**
- The `Trix` struct now has a `ChecksumAlgo` field to specify a hash algorithm.
- If set, `Encode` computes a checksum of the payload and adds it to the header.
- `Decode` verifies this checksum, returning an error if it doesn't match, ensuring data integrity during transit.
2. **Asymmetrical Sigils:**
- The `Sigils` field has been replaced with `InSigils` and `OutSigils` to support different transformation chains for packing and unpacking.
- If `OutSigils` is not set, `Unpack` defaults to using the `InSigils` chain to maintain the previous symmetrical behavior.
These features make the `Trix` container a more robust and self-verifying format for internal data transfer.
