OpenSSH Key and ED25519 support #39
Added _libssh2_explicit_zero() to explicitly zero sensitive data in memory #120
* ED25519 Key file support - Requires OpenSSL 1.1.1 or later
* OpenSSH Key format reading support - Supports RSA/DSA/ECDSA/ED25519 types
* New string buffer reading functions - These add build-in bounds checking and convenance methods. Used for OpenSSL PEM file reading.
* Added new tests for OpenSSH formatted Keys
This introduces a test suite for libssh2. It runs OpenSSH in a Docker
container because that works well on Windows (via docker-machine) as
well as Linux. Presumably it works on Mac too with docker-machine, but
I've not tested that.
Because the test suite is docker-machine aware, you can also run it
against a cloud provider, for more realistic network testing, by setting
your cloud provider as your active docker machine. The Appveyor CI setup
in this commit does that because Appveyor doesn't support docker
locally.
Despite we announced the CMake support in libssh2-1.6.0 release notes,
the files required by the CMake build system were not included in the
release tarballs. Hence, the only way to use CMake for build was the
upstream git repository.
This commit makes CMake actually supported in the release tarballs.
Do not create symbolic links off the build directory. Recent autotools
verify that out-of-source build works even if the source directory tree
is not writable.
1 - let libssh2 compile with OpenSSL 0.9.6b. This is due to 'crypt' is found
in one of its header files and EVP_MAX_BLOCK_LENGTH not being found.
2 - The EXEEXT patch is because automake 1.7 doesn't support it, and recent
automakes add it automatically
