Require code similair to below encrypt on decryption .
below code is to test encryption, similarly can i get code only for
testing decryption part of nettle.

aes_encrypt(&ctx, AES_BLOCK_SIZE, ciphertext, plaintext);
printf("AES_BLOCK_SIZE=%d", AES_BLOCK_SIZE);
printf("\nExpected: 14f5fe746966f292651c2288bbff4609\n");
printf("\nActual: ");
for (i = 0; i < 16; i++) {
printf("%02x", ciphertext[i]);
}
printf("\n");
return 0;
}
