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 restructures the `crypt` service to be more modular and decoupled from storage concerns.
- The standard cryptographic implementations (`lthn`, `chachapoly`, `rsa`) have been moved to the `pkg/crypt/std` directory.
- The `rootfs` components have been removed to decouple the library from storage.
- Import paths have been updated to reflect the new structure.
