The arguments `k`, `n`, `aadlen`, and `aad` are same in encryption/decryption. Note: Encryption and decryption can be executed in-place, i.e., `m` and `cipher` can point to the same memory. If decryption succeeds, the resulting plaintext is stored in `m` and the function returns the success code 0. If decryption fails, the array `m` remains unchanged and the function returns the error code 1. @param k Pointer to 32 bytes of memory where the AEAD key is read from. @param n Pointer to 12 bytes of memory where the AEAD nonce is read from. @param aadlen Length of the associated data. @param aad Pointer to `aadlen` bytes of memory where the associated data is read from. @param mlen Length of the ciphertext. @param m Pointer to `mlen` bytes of memory where the message is written to. @param cipher Pointer to `mlen` bytes of memory where the ciphertext is read from. @param mac Pointer to 16 bytes of memory where the mac is read from. @returns 0 on succeess; 1 on failure. */ uint32_t Hacl_Chacha20Poly1305_256_aead_decrypt( uint8_t *k, uint8_t *n, uint32_t aadlen, uint8_t *aad, uint32_t mlen, uint8_t *m, uint8_t *cipher, uint8_t *mac) { uint8_t computed_mac[16U] = { 0U }; uint8_t tmp[64U] = { 0U }; Hacl_Chacha20_Vec256_chacha20_encrypt_256((uint32_t)64U, tmp, tmp, k, n, (uint32_t)0U); uint8_t *key = tmp; poly1305_do_256(key, aadlen, aad, mlen, cipher, computed_mac); uint8_t res = (uint8_t)255U; KRML_MAYBE_FOR16(i, (uint32_t)0U, (uint32_t)16U, (uint32_t)1U, uint8_t uu____0 = FStar_UInt8_eq_mask(computed_mac[i], mac[i]); res = uu____0 & res;); uint8_t z = res; if (z == (uint8_t)255U) { Hacl_Chacha20_Vec256_chacha20_encrypt_256(mlen, m, cipher, k, n, (uint32_t)1U); return (uint32_t)0U; } return (uint32_t)1U; }
