I have problems in decrypting the text using AES in C. the code is belwo.
#include <stdlib.h>
#include <openssl/evp.h>
#include <string.h>
int main(){
//declaring the variables
char source[6]="Shahab";
char target[6];
char output[6];
char mykey[EVP_MAX_KEY_LENGTH]="hardtobreak";
char iv[EVP_MAX_IV_LENGTH] = "an_iv";
int in_len, out_len=0;
int check;
EVP_CIPHER_CTX ctx;
in_len=strlen(source);
printf("This is the text before ciphering: %s\n",source);
printf("The length of the string is: %d\n",in_len);
//starting the encryption process
EVP_CIPHER_CTX_init(&ctx);
EVP_EncryptInit_ex(&ctx,EVP_aes_128_cbc(),NULL,mykey,iv);
EVP_EncryptUpdate(&ctx,target,&out_len,source,in_len);
EVP_EncryptFinal_ex(&ctx,target,&out_len);
printf("The length of encrypted text is: %d\n",out_len);
//bzero(&source,sizeof(source));
//printf("The char array contains: %s\n",source);
in_len=strlen(target);
out_len=strlen(output);
EVP_DecryptInit_ex(&ctx,EVP_aes_128_cbc(),NULL,mykey,iv);
EVP_DecryptUpdate(&ctx,output,&out_len,target,in_len);
EVP_DecryptFinal_ex(&ctx,output,&out_len);
printf("The Desipher text is : %s\n",output);
printf("Program is working\n");
return 0;
}Thanks in advance for the help
