| Summary | 0006783: anonymous key fails at ECDHE | ||||
| Description | The ECDHE fails using the anonymous key pair even if all tests with randomly generated ECDSA key pairs succeed. This could be an issue caused by the util library in GNUnet, a mixture of using gcrypt and libsodium together or even an issue inside of libsodium. | ||||
| Steps To Reproduce | // Get the anonymous ECDSA key pair const struct GNUNET_CRYPTO_EcdsaPrivateKey* ecdsa_priv = GNUNET_CRYPTO_ecdsa_key_get_anonymous(); struct GNUNET_CRYPTO_EcdsaPublicKey ecdsa_pub; GNUNET_CRYPTO_ecdsa_key_get_public(ecdsa_priv, &ecdsa_pub); // Generate a random ECDHE key pair struct GNUNET_CRYPTO_EcdhePrivateKey ecdhe_priv; struct GNUNET_CRYPTO_EcdhePublicKey ecdhe_pub; GNUNET_CRYPTO_ecdhe_key_create(&ecdhe_priv); GNUNET_CRYPTO_ecdhe_key_get_public(&ecdhe_priv, &ecdhe_pub); // Derive hashes from the keys struct GNUNET_HashCode h1; struct GNUNET_HashCode h2; GNUNET_CRYPTO_ecdh_ecdsa(&ecdhe_priv, &ecdsa_pub, &h1); GNUNET_CRYPTO_ecdsa_ecdh(ecdsa_priv, &ecdhe_pub, &h2); // The hashes don't match..! GNUNET_assert(GNUNET_CRYPTO_hash_cmp(&h1, &h2) == 0); | ||||
| Additional Information | Currently this is not a huge issue because ECDHE gets used only in the identity API to encrypt and decrypt data for a specific ego. So the result is that encrypting data for the anonymous ego will fail. The functionality gets used by the messenger service but the service itself restricts encrypting messages to individually used egos (excluding the anonymous ego) in current state of development anyway. | ||||
