sir,
i have compiled this program in VC++.
#include <stdlib.h>
#include <stdio.h>
#include <rc4.h>
int main(void)
{
char plaintext[12] = "Hello World?";
char ciphertext[12];
char mykey[16] = "this's my secret";
RC4_KEY rc4_key;
RC4_set_key(&rc4_key, 16, mykey); /* the key is 128 bits or 16 bytes
long */
RC4(&rc4_key, 12, plaintext, ciphertext); /* plaintext is 12 bytes long
*/
printf("%s\n", plaintext);
printf("Encrypted: %s\n", ciphertext);
RC4_set_key(&rc4_key, 16, mykey); /* reset the key stream */
RC4(&rc4_key, 12, ciphertext, plaintext); /* start decryption */
printf("Decrypted: %s\n", plaintext);
exit(1);
}
compile was successfull. but i get linking error as follows.
i have installed and copied the include and lib files of openSSL to the
respective folders of VC++.
