wecanencrypt 0.5.0

//! # WeCanEncrypt
//!
//! A simple Rust OpenPGP library for encryption, signing, and key management using [rpgp](https://docs.rs/pgp).
//!
//! This library provides a functional API for common OpenPGP operations,
//! including:
//!
//! - **Key Generation**: Create RSA, Curve25519, or NIST curve keys
//! - **Encryption/Decryption**: Encrypt to one or multiple recipients
//! - **Signing/Verification**: Create and verify signatures
//! - **Certificate Management**: Parse, modify, and export certificates
//! - **Key Storage**: SQLite-backed keystore (optional feature)
//!
//! ## Quick Start
//!
//! ```no_run
//! use wecanencrypt::*;
//!
//! // Generate a new Curve25519 key (fast)
//! let key = create_key_simple("password", &["Alice <alice@example.com>"]).unwrap();
//!
//! // Encrypt a message
//! let ciphertext = encrypt_bytes(key.public_key.as_bytes(), b"Hello!", true).unwrap();
//!
//! // Decrypt it
//! let plaintext = decrypt_bytes(&key.secret_key, &ciphertext, "password").unwrap();
//! assert_eq!(plaintext, b"Hello!");
//! ```
//!
//! ## Cipher Suites
//!
//! The library supports multiple cipher suites:
//!
//! | Suite | Primary Key | Encryption Subkey | Speed |
//! |-------|-------------|-------------------|-------|
//! | `Cv25519` (default) | EdDSA Legacy | ECDH Curve25519 | Fast |
//! | `Cv25519Modern` | Ed25519 (RFC 9580) | X25519 | Fast |
//! | `NistP256` | ECDSA P-256 | ECDH P-256 | Fast |
//! | `NistP384` | ECDSA P-384 | ECDH P-384 | Fast |
//! | `NistP521` | ECDSA P-521 | ECDH P-521 | Fast |
//! | `Rsa2k` | RSA 2048-bit | RSA 2048-bit | Slow |
//! | `Rsa4k` | RSA 4096-bit | RSA 4096-bit | Very Slow |
//!
//! ## Features
//!
//! - `keystore`: Enable SQLite-backed key storage (requires `rusqlite`)
//! - `network`: Enable network operations for fetching keys from keyservers
//!
//! ## Design
//!
//! This library uses a functional API - all operations are standalone functions
//! that take certificate data as `&[u8]`. This provides maximum flexibility
//! and avoids the overhead of wrapper types.
