QBlockCipher

Example:

#include <QByteArray>

#include "QBlockCipher.h"

int main() {
    QSimpleCrypto::QBlockCipher blockCipher;

    QByteArray key = "AABBCCEEFFGGHHKKLLMMNNOOPPRRSSTT";
    QByteArray iv = "AABBCCEEFFGGHHKKLLMMNNOOPPRRSSTT";
    QByteArray salt = blockCipher.generateRandomBytes(8);

    QByteArray encrypted = blockCipher.encryptAesBlockCipher("Hello World!", key, iv, "password", salt, 14, EVP_aes_256_cbc(), EVP_sha512());
    QByteArray decrypted = blockCipher.decryptAesBlockCipher(encrypted, key, iv, "password", salt, 14, EVP_aes_256_cbc(), EVP_sha512());
}

Detailed Description

QByteArray generateRandomBytes(const int& size)

• size - Size of generated bytes

Returns random bytes. (Can be used for salt)

QByteArray encryptAesBlockCipher(QByteArray data, QByteArray key, QByteArray iv = "", QByteArray password = "", QByteArray salt = "", const int& rounds = 14, const EVP_CIPHER* cipher = EVP_aes_256_cbc(), const EVP_MD* md = EVP_sha512())

• data - Data that will be encrypted
• key - AES key. Example: "AABBCCEEFFGGHHKKLLMMNNOOPPRRSSTT"
• iv - Initialization vector. Example: "AABBCCEEFFGGHHKKLLMMNNOOPPRRSSTT"
• password - Encryption password
• salt - Random delta. Example: "qwerty123" or another random bytes generated with QSimpleCrypto::QBlockCipher::generateSalt.
• rounds - Transformation rounds
• cipher - Can be used with OpenSSL EVP_CIPHER (ecb, cbc, cfb, ofb, ctr) - 128, 192, 256. Example: EVP_aes_256_cbc()
• md - Hash algroitm (OpenSSL EVP_MD). Example: EVP_sha512()

Returns encrypted data on success and "" on failure.
