QAEAD

Example:

#include <QByteArray>

#include "QAEAD.h"

int main() {
    QByteArray key = "AABBCCEEFFGGHHKKLLMMNNOOPPRRSSTT";
    QByteArray iv = "AABBCCEEFFGGHHKKLLMMNNOOPPRRSSTT";
    QByteArray aad = "AABBCCDDEEFF";
    QByteArray tag = "AABBCCDDEEFF";

    QSimpleCrypto::QAEAD aead;
    QByteArray encrypted = aead.encryptAesGcm("Hello World", key, iv, &tag, aad);
    QByteArray decrypted = aead.decryptAesGcm(bytes, key, iv, &tag, aad);
}

Detailed Description

QByteArray encryptAesGcm(QByteArray data, QByteArray key, QByteArray iv, QByteArray* tag, QByteArray aad = "", const EVP_CIPHER* cipher = EVP_aes_256_gcm())

• data - Data that will be encrypted.
• key - AES key. Example: "AABBCCEEFFGGHHKKLLMMNNOOPPRRSSTT"
• iv - Initialization vector. Example: "AABBCCEEFFGGHHKKLLMMNNOOPPRRSSTT"
• tag - Authorization tag. Example: "AABBCCDDEEFF"
• aad - Additional authenticated data. Must be nullptr, if not used
• cipher - Can be used with OpenSSL EVP_CIPHER (gcm) - 128, 192, 256. Example: EVP_aes_256_gcm()

Returns encrypted data on success and "" on failure.
