chacha20poly1305: add some more XChaCha20-Poly1305 test vectors.
These vectors were generated with libsodium to ensure that Go is
compatible with that library:
#include <stdio.h>
#include <sodium.h>
#include <stdlib.h>
static void hexdump(const uint8_t *in, size_t in_len) {
printf("\t\t\"");
for (size_t i = 0; i < in_len; i++) {
printf("%02x", in[i]);
}
printf("\",\n");
}
int main() {
uint8_t nonce[24];
uint8_t key[32];
uint8_t m[64], c[64+16];
uint8_t ad[16];
for (size_t ad_len = 0; ad_len < sizeof(ad); ad_len += 4) {
for (size_t m_len = 0; m_len < sizeof(m); m_len += 5) {
randombytes(nonce, sizeof(nonce));
randombytes(key, sizeof(key));
randombytes(m, m_len);
randombytes(ad, ad_len);
unsigned long long c_len = sizeof(c);
if (crypto_aead_xchacha20poly1305_ietf_encrypt(c, &c_len, m, m_len, ad, ad_len, NULL, nonce, key)) {
abort();
}
printf("\t{\n");
hexdump(m, m_len);
hexdump(ad, ad_len);
hexdump(key, sizeof(key));
hexdump(nonce, sizeof(nonce));
hexdump(c, c_len);
printf("\t},\n");
}
}
return 0;
}
