Hi jesussotofan,
I have taken your code, re-compiled and run the test on Linux, I'm giving you my source code, just update the print statements and you should observe intended test case.
#include <stdio.h>
#include <wolfssl/options.h>
#include <wolfssl/wolfcrypt/settings.h>
#include <wolfssl/wolfcrypt/aes.h>
int main(void) {
Aes enc;
Aes dec;
int ret;
int x;
byte key[] = {"234567890abcdef"};
byte iv[] = {"1234567890abcdef"};
byte plain[32] = {"Hola mundoHola mundoHola mundo"}; // an increment of 16, fill with data
byte plain2[32];
byte cipher[32];
printf("sizeof key = %d\n", (int) sizeof(key));
printf("sizeof cipher = %d\n", (int) sizeof(cipher));
printf("sizeof plain = %d\n", (int) sizeof(plain));
printf("plain value ");
for(x=0; x<16; x++){
printf("%02x", plain[x]);
printf(" ");
}
printf(" \n");
printf("printing key value ");
for(x=0; x<16; x++){
printf("%02x", key[x]);
printf(" ");
}
printf(" \n");
printf("printing iv value ");
for(x=0; x<16; x++){
printf("%02x", iv[x]);
printf(" ");
}
printf(" \n");
//encrypt
ret = wc_AesSetKey(&enc, key, sizeof(key), iv, AES_ENCRYPTION);
if (ret != 0) {
printf("Encrypt set key failed with error: %d\n", ret);
return ret;
}
ret = wc_AesCbcEncrypt(&enc, cipher, plain, sizeof(plain));
if (ret != 0) {
printf("AesCbcEncrypt failed with error: %d\n", ret);
return ret;
}
printf("cipher value ");
for(x=0; x<16; x++){
printf("%02x", cipher[x]);
printf(" ");
}
printf(" \n");
printf("printing key value before cipher ");
for(x=0; x<16; x++){
printf("%02x", key[x]);
printf(" ");
}
printf(" \n");
printf("printing iv value before cipher ");
for(x=0; x<16; x++){
printf("%02x", iv[x]);
printf(" ");
}
printf(" \n");
//decrypt
ret = wc_AesSetKey(&dec, key, sizeof(key), iv, AES_DECRYPTION);
if (ret != 0) {
printf("Decrypt set key failed with error: %d\n", ret);
return ret;
}
ret = wc_AesCbcDecrypt(&dec, plain2, cipher, sizeof(cipher));
if (ret != 0) {
printf("AesCbcDecrypt failed with error: %d\n", ret);
return ret;
}
printf("plain2 value ");
for(x=0; x<16; x++){
printf("%02x", plain2[x]);
printf(" ");
}
printf(" \n");
printf(" \n");
printf(" \n");
