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 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 refactors the test suites for the `crypt` and `trix` packages to follow the Good, Bad, and Ugly testing strategy.
- `_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 new testing structure makes the test suite more organized, comprehensive, and robust.
Additionally, this commit includes a bug fix for the `Luhn` function, which now correctly handles empty and single-digit strings.
