1. Added Windows Visual Studio build solution. Includes projects for:
* wolfSSH static library
* echoserver
* unit-test
* api-test
* 32- and 64-bit debug and release builds for all
2. Made necessary tweaks including adding some wrapper functions so the code compiles for both Linux/macOS and Windows.
3. Fixed a bug in the KDF test where the output buffer wasn't updated when SHA-256 was added.
4. Added the fallthrough attribute for GCC7.
5. Replaced all uses of `uint8_t`, `uint16_t`, and `uint32_t` with the wolfCrypt provided `byte`, `word16`, and `word32`.
6. Split the new channel function into new and init.
7. Added some ECC keys for authentication testing.
8. Moved some functions and includes around.
9. Removed the keying state machine and replaced with a flag.
10. Added rekey trigger if the client sends *CTRL-F* to echoserver.
11. Moved the sequence number increase outside `CreateMac()`. Incremented if the packet was successfully created. This way the sequence number is incremented when using AES-GCM.
12. Removed the redundant function `SendText()`.
13. Renamed the `clientId` related functions and data members to `protoId` to keep things role agnostic.
14. Changed all references of `clientKey` and `serverKey` to `keys` and `peerKeys`.
15. Updated `GenerateKeys()` to generate `keys` and `peerKeys` appropriately based on the endpoint side.
16. Added the wolfSSL style _test.h_ file to group shared example functions in one place.
17. Changed the echoserver to be similar to wolfSSL's where the code may be included without the main function in another executable.
Note:
This commit is a squash of more than a dozen commits. IDE support was added to the client branch, but the client branch is on hold. There were many changes in the client branch that are needed going forward. The code at the head of the client branch was copied over to the IDE branch, and the client code either deleted or removed from the build.
Updated the two projects with similar settings so they build without warnings. The wolfSSH library project needs the wolfSSL header path added before building. The api-test project needs the wolfSSL library added before building.
1. Added a user_settings.h file to be used with building wolfSSL.
2. Removed misc.c from the wolfSSH library project.
3. Added the WOLFSSL_USER_SETTINGS define to the wolfSSH library project.
4. Replaced vsnprintf() and localtime_r() with macros to use the correct functions for Win32 builds.
5. Replaced the misc.c warning with the VS style of doing it if building for Win32.
6. Defined USE_WINDOWS_API if _WIN32 is set.
Note: The wolfSSH library builds in 32-bit Debug mode. To do so, you need to add the directory holding the wolfSSL headers to the AdditionalIncludeDirectories list.
* Renamed the server key files to indicate they are rsa keys.
* Add ecc key files for the server.
* Move ProcessBuffer from ssh.c to internal.c.
* Remove #includes for headers from files that are not used.
* Added support for KEX algorithms: ecdh-sha2-nistp256, ecdh-sha2-nistp384, ecdh-sha2-nistp521
* Updated readme
* Added support for the public key algorithm ecdsa-sha2-nistp256.
* Added support for public key algorithms ecdsa-sha2-nistp384 and ecdsa-sha2-nistp521.
* The Key Algorithm list for the KEX picks a single value to offer based on the private key used.
* Added private keys on curves nistp384 and nistp521. The curve nistp256 is used as the default.
* Added the new ecc keys to include.am
2. Add wolfSSH_GetStats() to return session statistics.
3. Echoserver server_worker threads get a context with their
wolfSSH session, an ID number, and socket fd.
Filled out the message handling for the DH-GEX additional messages. To use
the DH-GEX, one needs to add the flag TEST_GEX. It is still a WIP. The
handshake state machine needs a change and the start of the hash calculation
needs to wait until receiving the client's KEX INIT message and the hash
type for the handshake signature can be resolved.
1. Added support for the wc_Hash wrappers. Need to keep track of the
hash being used.
2. Assumed SHA1 only, and modified everything to use the hash wrappers.
1. Add the banner to the WOLFSSH_CTX.
2. Moved the canned banner to be a debug option.
3. Default the banner to NULL of zero length.
4. Use the banner stored in the WOLFSSH_CTX.
5. Add an accessor to set the banner to a C string.
1. Added parsing of the Global Request message. Will log the request
name string.
2. Send global request failure response if reply is requested.
(This was an issue with a particular SSH client.)
client version string.
2. Shrink the receive buffer after reading the client version
string.
3. Resize the buffer correctly when needed data is already in the input
buffer and grab the remainder as expected.
