Subject: [PATCH 1/9] feat: Add OpenPGP implementation

Adds a full implementation of OpenPGP features using ProtonMail's go-crypto fork.

- Implements PGP key generation, encryption, and decryption.
- Exposes PGP functionality through the crypt.Service.
- Adds tests for the PGP implementation.

Subject: [PATCH 2/9] feat: Expand OpenPGP implementation

Expands the existing OpenPGP implementation to include a more complete set of features for handling PGP data.

- Adds support for signing and verifying detached signatures.
- Adds support for symmetric encryption using a passphrase.
- Includes tests for all new functionality.

Subject: [PATCH 4/9] test: Increase test coverage

Increases the test coverage of the project from 85.5% to 89.2%.

- Adds tests for the `IsHashAlgo` function and PGP functions in `pkg/crypt`.
- Adds tests for the `main` function and command handlers in `cmd/trix`.
- Improves the overall test coverage of the `cmd/trix` package from 26.0% to 67.7%.
- Improves the overall test coverage of the `pkg/crypt` package from 78.2% to 96.2%.

Subject: [PATCH 5/9] docs: Add feature examples

Adds a comprehensive set of examples to demonstrate the library's features.

- Breaks out the existing `examples/main.go` into separate, well-named files.
- Adds new examples for hashing, checksums, RSA, and PGP.
- The PGP examples cover key generation, encryption/decryption, signing/verification, and symmetric encryption.
- Removes the old `examples/main.go` file and formats the new example files.

Subject: [PATCH 6/9] test: Improve test coverage and add examples

Improves the test coverage of the project and adds examples for coverage reports.

- Increases the test coverage of the `cmd/trix` package from 67.7% to 78.1%.
- Increases the test coverage of the `pkg/crypt` package from 96.2% to 98.7%.
- Adds tests for the `examples` to ensure they run without errors.
- Adds a new example that demonstrates how to generate and interpret a coverage report.

 Enchantrix is a Go-based encryption library designed to provide a secure and easy-to-use framework for handling sensitive data in Web3 applications. It will feature Poly-ChaCha stream proxying and a custom `.trix` file format for encrypted data.
