| * Cipher_Mode API improvementsJack Lloyd2016-09-0127-290/+242
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Cipher_Mode::update API is more general than needed to just support ciphers (this is due to it previously being an API of Transform which before 8b85b780515 was Cipher_Mode's base class) Define a less general interface `process` which either processes the blocks in-place, producing exactly as much output as there was input, or (SIV/CCM case) saves the entire message for processing in `finish`. These two uses cover all current or anticipated cipher modes. Leaves `update` for compatability with existing callers; all that is needed is an inline function forwarding to `process`. Removes the return type from `start` - in all cipher implementations, this always returned an empty vector. Adds BOTAN_ARG_CHECK macro; right now BOTAN_ASSERT is being used for argument checking in some places, which is not right at all.
* | Merge GH #630 TLS server checks client signature_algorithmsJack Lloyd2016-09-245-31/+89

| * | TLS Server should respect client signature_algorithms. Stricter TLS hello ↵Jack Lloyd2016-09-215-31/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | decoding. If the client sent a signature_algorithms extension, we should negotiate a ciphersuite in the shared union of the ciphersuite list and the extension, instead of ignoring it. Found by Juraj Somorovsky GH #619 The TLS v1.2 spec says that clients should only send the signature_algorithms extension in a hello for that version. Enforce that when decoding client hellos to prevent this extension from confusing a v1.0 negotiation. TLS v1.2 spec says ANON signature type is prohibited in the signature_algorithms extension in the client hello. Prohibit it. Reorder the TLS extensions in the client hello so there is no chance an empty extension is the last extension in the list. Some implementations apparently reject such hellos, even (perhaps especially) when they do not recognize the extension, this bug was mentioned on the ietf-tls mailing list a while back.

| * | | Fix validation of self-issued certificates in chainsRené Korthaus2016-09-232-2/+5
| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Self-issued certificates are certificates where subject_dn == issuer_dn, but the signature is from a different key (ca key). Chains with such a certificate could not be verified, because self-issued certificates (1) would be taken for a self-signed certificate and (2) find_issuing_cert() would find the same self-issued certificate that we want to verify, generating a signature error during signature verification. To fix, we now first identify a certificate as self-signed only if subject_dn == issuer_dn AND if we can verify the cert signature with it's own key. Verification will bring some extra costs, but we only do it once, in X509_Certificate's constructor. Second, we make sure find_issuing_cert() does not return the very same certificate we want to verify. This should be no problem, since path validation currently does not seem to support validating a self-signed certificate.

* | Merge optimized implementations into base classJack Lloyd2016-09-1532-708/+460
| | | | | | | | | | | | | | | | | | | | Various algorithms had an optimized implementation (for SSE2, AVX2, etc) which was offered alongside the 'base' implementation. This is admittedly very useful for testing, but it breaks user expectations in bad ways. See GH #477 for background. Now encrypting with `AES_128` (say) just runs whatever implementation is best on the current processor/build.

Default impl checks that the algorithm size matches the min keylength. This centralizes this logic and lets the application do interesting things. Adds a policy for ECDSA group size checks. Increases default policy minimums to 2048 RSA and 256 ECC. (Maybe I'm an optimist after all.)

This avoids the overhead of empty std::functions when using the virtual interface, and ensures the virtual interface works since there is no callback path that does not involve a vtable lookup. Rename the TLS::Callback functions. Since the idea is that often an owning class will pass *this as the callbacks argument, it is good to namespace the virtual functions so as not to conflict with other names chosen by the class. Specifically, prefixes all cb functions with tls_ Revert changes to use the old style alert callback (with no longer used data/len params) so no API changes are required for old code. The new Callbacks interface continues to just receive the alert code itself. Switch to virtual function interface in CLI tls_client for testing. Inline tls_server_handshake_state.h - only used in tls_server.cpp Fix tests - test looked like it was creating a new client object but it was not actually being used. And when enabled, it failed because the queues were not being emptied in between. So, fix that.
