# wecanencrypt
Simple Rust OpenPGP library for encryption, signing, and key management, built on top of [rpgp](https://github.com/rpgp/rpgp).
## Features
- **Key Generation**: Create OpenPGP keys with various cipher suites (Cv25519, RSA2k, RSA4k, NIST P-256/P-384/P-521)
- **Encryption/Decryption**: Encrypt and decrypt files and byte streams
- **Signing/Verification**: Sign messages (inline, cleartext, detached) and verify signatures
- **Key Parsing**: Parse certificates from files or bytes, extract key information
- **Keyring Support**: Parse and export GPG keyrings
- **SSH Key Export**: Convert OpenPGP authentication keys to SSH public key format
- **Network Operations**: Fetch keys via WKD (Web Key Directory) and HKP keyservers
- **KeyStore**: SQLite-backed key storage with search and management capabilities
## Usage
```rust
use wecanencrypt::{create_key, encrypt_bytes, decrypt_bytes, CipherSuite, SubkeyFlags};
// Generate a new key
let key = create_key(
"passphrase",
&["Alice <alice@example.com>"],
CipherSuite::Cv25519,
None, None, None,
SubkeyFlags::default(),
false,
true,
)?;
// Encrypt data
let plaintext = b"Hello, World!";
let encrypted = encrypt_bytes(plaintext, &[&key.public_key.as_bytes()])?;
// Decrypt data
let decrypted = decrypt_bytes(&encrypted, &key.secret_key.as_bytes(), "passphrase")?;
```
## Optional Features
- `keystore` (default): SQLite-backed key storage
- `network` (default): WKD and HKP key fetching
