i need use aes_decrypt and aes_encrypt in c++ AES256_Method = AES-256-CFB in make iv same in php to can in c++ decrypt and encrypt aes 256 this in php static public function aes_encrypt($input) { $key = substr(hash(‘sha256’, Config::AES256_Password, false), 0, 32); $iv_len = openssl_cipher_iv_length(Config::AES256_Method); $iv = openssl_random_pseudo_bytes($iv_len); $ciphertext = openssl_encrypt($input, Config::AES256_Method, $key, OPENSSL_RAW_DATA, $iv); $encrypted ..

I have a python endpoint that encrypts string using AES cbc mode and returns it to the client software written in c++ (in a hex space separated format ) The link for the c++ repo std::vector<unsigned char> cipher_as_chars(std::string cipher) { std::istringstream strm{cipher}; strm >> std::hex; std::vector<unsigned char> res; res.reserve(cipher.size() / 3 + 1); int h; ..

In my quest for a single header encryption library for c++ I found this github repo that uses AES with CBC mode to encrypt a std::string into a vector of unsigned char in the example provided in the repo this const unsigned char iv[16] = { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, ..

I’m trying to extend the encrypted message with mbedtls/aes.h This is my code: void encrypt(char * plainText, char * key, unsigned char * outputBuffer){ mbedtls_aes_context aes; mbedtls_aes_init( &aes ); mbedtls_aes_setkey_enc( &aes, (const unsigned char*) key, strlen(key) * 8 ); mbedtls_aes_crypt_ecb( &aes, MBEDTLS_AES_ENCRYPT, (const unsigned char*)plainText, outputBuffer); mbedtls_aes_free( &aes ); } void decrypt(unsigned char * chipherText, ..
