Installation

Add to your Cargo.toml:

[dependencies]
crypt-ro =  "1.0.0"

Usage Example

use crypt_ro::Cryptor;

fn process_chat_messages() {
    let cryptor = Cryptor::new();
    let key = "session-key-abc123";
    
    // Encrypt 1000 messages in milliseconds
    let messages: Vec<String> = /* ... */;
    let encrypted: Vec<_> = messages.iter()
        .map(|msg| cryptor.encrypt_text(msg, key).unwrap())
        .collect();
    
    // Decrypt just as fast
    let decrypted: Vec<_> = encrypted.iter()
        .map(|cipher| cryptor.decrypt_text(cipher, key).unwrap())
        .collect();
}

Basic Text Encryption

use crypt_ro::Cryptor;

fn test(){
    let cryptor = Cryptor::new();
    let secret = "My confidential message";
    let key = "strong-password-123";

    // Encrypt
    let encrypted = cryptor.encrypt_text(secret, key).unwrap();

    // Decrypt
    let decrypted = cryptor.decrypt_text(&encrypted, key).unwrap();

    assert_eq!(decrypted, secret);
}

Binary Data Encryption

use crypt_ro::Cryptor;

fn test(){
    let cryptor = Cryptor::new();
    let data = b"\x01\x02\x03binary\xff\xfe\xfd";
    let key = "encryption-key";

    // Encrypt raw bytes
    let encrypted = cryptor.encrypt(data, key).unwrap();

    // Decrypt
    let decrypted = cryptor.decrypt(&encrypted, key).unwrap();

    assert_eq!(decrypted, data);
}

Custom Matrix Size

use crypt_ro::Cryptor;

fn test(){
    let mut cryptor = Cryptor::new();
    cryptor.set_matrix(64); // Use 64-byte blocks

    let encrypted = cryptor.encrypt_text("data", "key").unwrap();
    let decrypted = cryptor.decrypt_text(&encrypted, "key").unwrap();

    assert_eq!(decrypted, "data");
}

When to Use

✅ High-volume encryption (logging, metrics, telemetry)
✅ Low-latency requirements (real-time systems)
✅ Resource-constrained environments
✅ Temporary data protection (session tokens, cache)

Performance

Crypt-ro delivers blazing-fast encryption/decryption speeds, competitive with industry-standard algorithms:

Algorithm	Operation	50B Data	Comparison
Cryptor	Encrypt	343-350 ns	Reference
Cryptor	Decrypt	369-370 ns	Reference
AES-256-GCM	Encrypt	460-461 ns	~1.3x slower
AES-256-GCM	Decrypt	459-460 ns	~1.3x slower
RSA-2048	Encrypt	172.26-172.29 μs	~500x slower
RSA-2048	Decrypt	1.424-1.426 ms	~4000x slower

Key Advantages:

⚡ Sub-microsecond operations for small data
🔥 Decryption is 15-20% faster than AES-256-GCM
🚀 3000x faster than RSA for decryption

Security Considerations

While extremely fast, Crypt-ro uses:

Random initialization vectors
Multiple transformation layers
Defense in depth strategy Security Notes
This library uses a custom encryption algorithm - not peer-reviewed
Not recommended for highly sensitive data
Always use strong, complex keys
