* Reduction of code complexity in MP & ECC classes.Matthias Gierlings2016-06-1912-135/+114
| | | | | | - reduced number of parameters in various methods - introduced structures and renamed variables to improve code readability.
* Reduction of code complexity in TLS classes.Matthias Gierlings2016-06-1929-942/+1256
| | | | | | | -reduced number of parameters in various methods -reduced cyclomatic complexity (McCabe-Metric) -removed "TLSEXT_HEARTBEAT_SUPPORT" from tls_extensions.h (leftover from heartbeat extension removal?)
* Use https:// urls for randombit.net links.Jack Lloyd2016-06-191-3/+3
| | | | | | | | | Previously avoided since many clients don't have the CACert root, but now that Let's Encrypt is used instead anyone with a recent trust root should accept the certs for botan.randombit.net and lists.randombit.net [ci skip]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The LLVM apt mirror was removed due to excessive load, preventing us from installing a new enough Clang for our needs. However CircleCI also supports Ubuntu 14.04 images, instead of the Ubuntu 12 we were on. The new version has GCC 4.8 and Clang 3.4 as the base install. Removes UBSan from the CircleCI sanitizer build, since that requires at least GCC 4.9 GH #498

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds support for probabilistic, aka the standard, DSA and ECDSA. Can be enabled by disabling the rfc6979 module. Includes test vectors from NIST CAVP. Adds rfc6979 to the list of prohibited modules in BSI policy.

* | | | Remove DN field requirements on generating certs and PKCS #10Jack Lloyd2016-05-233-22/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have no idea why this is requiring the country code be set, but for many applications a country is not even meaningful. This change also allows CN to be empty/unset on the request or cert, since there is no actual requirement for any specific DN entry type and RFC 5280 specifically allows even an completely empty DN, with name information only in the subjectAltName extension. This change also allows generating a self-signed cert or cert request that expires before it starts. That could only happen with an explicit decision by the application to set it that way, and there is no harm in returning these non-secret bits. They will probably notice their problem as soon as the cert is rejected by any receiving system.
* | | | Fix GCM counter incrementJack Lloyd2016-05-234-3/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GCM is defined as having a 32-bit counter, but CTR_BE incremented the counter across the entire block. This caused incorrect results if a very large message (2**39 bits) was processed, or if the GHASH derived nonce ended up having a counter field near to 2**32 Thanks to Juraj Somorovsky for the bug report and repro.

| | | | | | | | | | | | | | | | | | Move disabling C4250 and C4251 to cmd line instead of header pragma. This means these warnings will show up in application code. But disabling warnings inside a library header is probably not good form.

| * Generate error on unknown critical extension during path validationRené Korthaus2016-04-069-19/+145
| | | | | | | | | | | | | | | | | | | | | | | | Previously unknown critical extensions were rejected during X509_Certificate constructor, which inhibited inspecting other parts of such a certificate. Refactored the certificate extensions code so that the path validation routine performs this check only. Additionally, added an interface for extensions to inspect the path during path validation. TODOs were added in places where existing path validation code can use the new interface. Fixes GH #449.

| * | Remove Transform base classJack Lloyd2016-04-2134-637/+615
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With sufficient squinting, Transform provided an abstract base interface that covered both cipher modes and compression algorithms. However it mapped on neither of them particularly well. In addition this API had the same problem that has made me dislike the Pipe/Filter API: given a Transform&, what does it do when you put bits in? Maybe it encrypts. Maybe it compresses. It's a floor wax and a dessert topping! Currently the Cipher_Mode interface is left mostly unchanged, with the APIs previously on Transform just moved down the type hierarchy. I think there are some definite improvements possible here, wrt handling of in-place encryption, but left for a later commit. The compression API is split into two types, Compression_Algorithm and Decompression_Algorithm. Compression_Algorithm's start() call takes the compression level, allowing varying compressions with a single object. And flushing the compression state is moved to a bool param on `Compression_Algorithm::update`. All the nonsense WRT compression algorithms having zero length nonces, input granularity rules, etc as a result of using the Transform interface goes away.

* | Don't reject TLS packets with zero plaintext bytesJack Lloyd2016-04-152-13/+19
| | | | | | | | | | | | | | | | OpenSSL sends an empty record before each new data record in TLS v1.0 to randomize the IV, as a countermeasure to the BEAST attack. Most implementations use 1/(n-1) splitting for this instead. Bug introduced with the const time changes in 1.11.23
