dear all
i am using Authenticated Encryption AES-GCM. i am trying to calculate the
processing time for encrypting a data message of size 500 byte
clock_t startEncryption, endEncryption;
double msecs1;
startEncryption = clock();
unsigned char plaintext[500] =
{'f','a','3','1','3',
dear all
i'm trying to use AES-GCM model for encryption i use a sample code for that
and my problem is
ret = EVP_DecryptFinal_ex(ctx, plaintext + len, &len);
ret all the time is 0 this means that
the plaintext is not trustworthy.
