-	* --enable-crypt-none
+Source code: https://github.com/libssh2/libssh2
 
-		The SSH2 Transport allows for unencrypted data
-		transmission using the "none" cipher.  Because this is
-		such a huge security hole, it is typically disabled on
-		SSH2 implementations and is disabled in libssh2 by
-		default as well.
+Web site source code: https://github.com/libssh2/www
 
-		Enabling this option will allow for "none" as a
-		negotiable method, however it still requires that the
-		method be advertized by the remote end and that no
-		more-preferable methods are available.
-
-	* --enable-mac-none
-
-		The SSH2 Transport also allows implementations to
-		forego a message authentication code.  While this is
-		less of a security risk than using a "none" cipher, it
-		is still not recommended as disabling MAC hashes
-		removes a layer of security.
-
-		Enabling this option will allow for "none" as a
-		negotiable method, however it still requires that the
-		method be advertized by the remote end and that no
-		more-preferable methods are available.
-
-	* --disable-gex-new
-
-		The diffie-hellman-group-exchange-sha1 (dh-gex) key
-		exchange method originally defined an exchange
-		negotiation using packet type 30 to request a
-		generation pair based on a single target value.  Later
-		refinement of dh-gex provided for range and target
-		values.  By default libssh2 will use the newer range
-		method.
-
-		If you experience trouble connecting to an old SSH
-		server using dh-gex, try this option to fallback on
-		the older more reliable method.
-
-  	* --with-libgcrypt
-  	* --without-libgcrypt
-	* --with-libgcrypt-prefix=DIR
-
-		libssh2 can use the Libgcrypt library
-		(http://www.gnupg.org/) for cryptographic operations.
-		Either Libgcrypt or OpenSSL is required.
-
-		Configure will attempt to locate Libgcrypt
-		automatically.

-# libssh2
-
-libssh2 is a client-side C library implementing the SSH2 protocol.
-
-# Building for PHP
-
-libssh2 depends on openssl and zlib. To build follow these steps:
-
-* create a directory named "deps" at the level of the libssh2 source dir and put the dependencies there
-* build libssh2
- * use win32/libssh2.vcproj to build with VS2008
- * use win32/libssh2.vc11.sln to build with VS2012

+    Definitions needed to implement a specific crypto library
+
+This document offers some hints about implementing a new crypto library
+interface.
+
+A crypto library interface consists of at least a header file, defining
+entities referenced from the libssh2 core modules.
+Real code implementation (if needed), is left at the implementor's choice.
+
+This document lists the entities that must/may be defined in the header file.
+
+Procedures listed as "void" may indeed have a result type: the void indication
+indicates the libssh2 core modules never use the function result.
+
+
+0) Build system.
+
+Adding a crypto backend to the autotools build system (./configure) is easy:
+
+0.1) Add one new line in configure.ac
+
+m4_set_add([crypto_backends], [newname])
+
+This automatically creates a --with-crypto=newname option.
+
+0.2) Add an m4_case stanza to LIBSSH2_CRYPTO_CHECK in acinclude.m4
+
+This must check for all required libraries, and if found set and AC_SUBST a
+variable with the library linking flags. The recommended method is to use
+LIBSSH2_LIB_HAVE_LINKFLAGS from LIBSSH2_CRYPTO_CHECK, which automatically
+creates and handles a --with-$newname-prefix option and sets an
+LTLIBNEWNAME variable on success.
+
+0.3) Create Makefile.newname.inc in the top-level directory
+
+This must set CRYPTO_CSOURCES, CRYPTO_HHEADERS and CRYPTO_LTLIBS.
+Set CRYPTO_CSOURCES and CRYPTO_HHEADERS to the new backend source files
+and set CRYPTO_LTLIBS to the required library linking parameters, e.g.
+$(LTLIBNEWNAME) as generated by by LIBSSH2_LIB_HAVE_LINKFLAGS.
+
+0.4) Add a new block in src/Makefile.am
+
+if NEWNAME
+include ../Makefile.newname.inc
+endif
+
+
+1) Crypto library initialization/termination.
+
+void libssh2_crypto_init(void);
+Initializes the crypto library. May be an empty macro if not needed.
+
+void libssh2_crypto_exit(void);
+Terminates the crypto library use. May be an empty macro if not needed.

+
+void libssh2_hmac_ctx_init(libssh2_hmac_ctx ctx);

+Continue computation of an HMAC on datalen bytes at data using context ctx.
+Note: if the ctx parameter is modified by the underlying code,

+minimum data buffer size depends on the HMAC hash algorithm.

+When Building directly from Master
+==================================
+
+If you want to build directly from the git repository, you must first
+generate the configure script and Makefile using autotools. There is
+a convenience script that calls all tools in the correct order. Make
+sure that autoconf, automake and libtool are installed on your system,
+then execute:
+
+  autoreconf -fi
+
+After executing this script, you can build the project as usual:
+
+  ./configure
+  make

+More configure options
+======================
+
+Some ./configure options deserve additional comments:

+
+	The SSH2 Transport allows for unencrypted data
+	transmission using the "none" cipher.  Because this is
+	such a huge security hole, it is typically disabled on

+
+	Enabling this option will allow for "none" as a

+
+ * --enable-mac-none
+
+	The SSH2 Transport also allows implementations to
+	forego a message authentication code.  While this is
+	less of a security risk than using a "none" cipher, it
+	is still not recommended as disabling MAC hashes

+
+Installation instructions are in docs/INSTALL
+=======
+To build libssh2 you will need CMake v2.8 or later [1] and one of the
+following cryptography libraries:
+
+* OpenSSL
+* Libgcrypt
+* WinCNG
+* mbedTLS
+
+Getting started
+---------------
+
+If you are happy with the default options, make a new build directory,
+change to it, configure the build environment and build the project:
+
+```
+  mkdir bin
+  cd bin
+  cmake ..
+  cmake --build .
+```
+
+libssh2 will be built as a static library and will use any
+cryptography library available.  The library binary will be put in
+`bin/src`, with the examples in `bin/example` and the tests in
+`bin/tests`.
+
+Customising the build
+---------------------
+
+Of course, you might want to customise the build options.  You can
+pass the options to CMake on the command line:
+
+  cmake -D<option>=<value> ..
+
+The following options are available:
+
+ * `LINT=ON`
+
+    Enables running the source code linter when building. Can be `ON` or `OFF`.
+
+
+ * `BUILD_SHARED_LIBS=OFF`
+
+    Determines whether libssh2 is built as a static library or as a
+    shared library (.dll/.so).  Can be `ON` or `OFF`.
+
+ * `CRYPTO_BACKEND=`
+
+    Chooses a specific cryptography library to use for cryptographic
+    operations.  Can be `OpenSSL` (https://www.openssl.org),
+    `Libgcrypt` (https://www.gnupg.org/), `WinCNG` (Windows Vista+),
+    `mbedTLS` (https://tls.mbed.org/) or blank to use any library available.
+
+    CMake will attempt to locate the libraries automatically.  See [2]
+    for more information.
+
+ * `ENABLE_ZLIB_COMPRESSION=OFF`
+
+    Will use zlib (http://www.zlib.org) for payload compression.  Can
+    be `ON` or `OFF`.
+
+ * `ENABLE_CRYPT_NONE=OFF`
+
+    The SSH2 Transport allows for unencrypted data transmission using
+    the "none" cipher.  Because this is such a huge security hole, it
+    is typically disabled on SSH2 implementations and is disabled in
+    libssh2 by default as well.
+
+    Enabling this option will allow for "none" as a negotiable method,
+    however it still requires that the method be advertized by the
+    remote end and that no more-preferable methods are available.
+
+ * `ENABLE_MAC_NONE=OFF`
+
+    The SSH2 Transport also allows implementations to forego a message
+    authentication code.  While this is less of a security risk than
+    using a "none" cipher, it is still not recommended as disabling
+    MAC hashes removes a layer of security.
+
+    Enabling this option will allow for "none" as a negotiable method,
+    however it still requires that the method be advertized by the
+    remote end and that no more-preferable methods are available.
+
+ * `ENABLE_GEX_NEW=ON`
+
+    The diffie-hellman-group-exchange-sha1 (dh-gex) key exchange
+    method originally defined an exchange negotiation using packet
+    type 30 to request a generation pair based on a single target
+    value.  Later refinement of dh-gex provided for range and target
+    values.  By default libssh2 will use the newer range method.
+
+    If you experience trouble connecting to an old SSH server using
+    dh-gex, try this option to fallback on the older more reliable
+    method.
+
+ * `ENABLE_DEBUG_LOGGING=ON` in Debug, `=OFF` in Release
+
+    Will enable the libssh2_trace() function for showing debug traces.
+
+ * `CLEAR_MEMORY=ON`
+
+    Securely zero memory before freeing it (if the backend supports this).
+
+Build tools
+-----------
+
+The previous examples used CMake to start the build using:
+
+  cmake --build .
+
+Alternatively, once CMake has configured your project, you can just
+use your own build tool, e.g GNU make, Visual Studio, etc., from that
+point onwards.
+
+Tests
+-----
+
+To test the build, run the appropriate test target for your build
+system.  For example:
+
+```
+  cmake --build . --target test
+```
+or
+```
+  cmake --build . --target RUN_TESTS
+```
+
+How do I use libssh2 in my project if my project doesn't use CMake?
+-------------------------------------------------------------------
+
+If you are not using CMake for your own project, install libssh2
+```
+  cmake <libssh2 source location>
+  cmake --build .
+  cmake --build . --target install
+```
+or
+```
+  cmake --build . --target INSTALL
+```
+
+and then specify the install location to your project in the normal
+way for your build environment.  If you don't like the default install
+location, add `-DCMAKE_INSTALL_PREFIX=<chosen prefix>` when initially
+configuring the project.
+
+How can I use libssh2 in my project if it also uses CMake?
+----------------------------------------------------------
+
+If your own project also uses CMake, you don't need to worry about
+setting it up with libssh2's location.  Just add just the following
+lines and CMake will find libssh2 on your system, set up the necessary
+paths and link the library with your binary.
+
+    find_package(Libssh2 REQUIRED CONFIG)
+    target_link_libraries(my_project_target Libssh2::libssh2)
+
+Of course, you still have to make libssh2 available on your system
+first.  You can install it in the traditional way shown above, but you
+don't have to.  Instead you can just build it, which will export its
+location to the user package registry [3] where `find_package` will
+find it.
+
+You can even combine the two steps using a so-called 'superbuild'
+project [4] that downloads, builds and exports libssh2, and then
+builds your project:
+
+    include(ExternalProject)
+
+    ExternalProject_Add(
+        Libssh2
+        URL <libssh2 download location>
+        URL_HASH SHA1=<libssh2 archive SHA1>
+        INSTALL_COMMAND "")
+
+    ExternalProject_Add(
+        MyProject DEPENDS Libssh2
+        SOURCE_DIR ${CMAKE_CURRENT_SOURCE_DIR}/src
+        INSTALL_COMMAND "")

+libssh2 security
+================
+
+This document is intended to provide guidance on how security vulnerabilities
+should be handled in the libssh2 project.
+
+Publishing Information
+----------------------
+
+All known and public libssh2 vulnerabilities will be listed on [the libssh2
+web site](https://www.libssh2.org/).
+
+Security vulnerabilities should not be entered in the project's public bug
+tracker unless the necessary configuration is in place to limit access to the
+issue to only the reporter and the project's security team.
+
+Vulnerability Handling
+----------------------
+
+The typical process for handling a new security vulnerability is as follows.
+
+No information should be made public about a vulnerability until it is
+formally announced at the end of this process. That means, for example that a
+bug tracker entry must NOT be created to track the issue since that will make
+the issue public and it should not be discussed on the project's public
+mailing list. Also messages associated with any commits should not make any
+reference to the security nature of the commit if done prior to the public
+announcement.
+
+- The person discovering the issue, the reporter, reports the vulnerability
+  privately to `libssh2-security@haxx.se`. That's an email alias that reaches a
+  handful of selected and trusted people.
+
+- Messages that do not relate to the reporting or managing of an undisclosed
+  security vulnerability in libssh2 are ignored and no further action is
+  required.
+
+- A person in the security team sends an e-mail to the original reporter to
+  acknowledge the report.
+
+- The security team investigates the report and either rejects it or accepts
+  it.
+
+- If the report is rejected, the team writes to the reporter to explain why.
+
+- If the report is accepted, the team writes to the reporter to let him/her
+  know it is accepted and that they are working on a fix.
+
+- The security team discusses the problem, works out a fix, considers the
+  impact of the problem and suggests a release schedule. This discussion
+  should involve the reporter as much as possible.
+
+- The release of the information should be "as soon as possible" and is most
+  often synced with an upcoming release that contains the fix. If the
+  reporter, or anyone else, thinks the next planned release is too far away
+  then a separate earlier release for security reasons should be considered.
+
+- Write a security advisory draft about the problem that explains what the
+  problem is, its impact, which versions it affects, solutions or
+  workarounds, when the release is out and make sure to credit all
+  contributors properly.
+
+- Request a CVE number from
+  [distros@openwall](http://oss-security.openwall.org/wiki/mailing-lists/distros)
+  when also informing and preparing them for the upcoming public security
+  vulnerability announcement - attach the advisory draft for information. Note
+  that 'distros' won't accept an embargo longer than 14 days.
+
+- Update the "security advisory" with the CVE number.
+
+- The security team commits the fix in a private branch. The commit message
+  should ideally contain the CVE number. This fix is usually also distributed
+  to the 'distros' mailing list to allow them to use the fix prior to the
+  public announcement.
+
+- At the day of the next release, the private branch is merged into the master
+  branch and pushed. Once pushed, the information is accessible to the public
+  and the actual release should follow suit immediately afterwards.
+
+- The project team creates a release that includes the fix.
+
+- The project team announces the release and the vulnerability to the world in
+  the same manner we always announce releases. It gets sent to the libssh2
+  mailing list and the oss-security mailing list.
+
+- The security web page on the web site should get the new vulnerability
+  mentioned.
+
+LIBSSH2-SECURITY (at haxx dot se)
+--------------------------------
+
+Who is on this list? There are a couple of criteria you must meet, and then we
+might ask you to join the list or you can ask to join it. It really isn't very
+formal. We basically only require that you have a long-term presence in the
+libssh2 project and you have shown an understanding for the project and its way
+of working. You must've been around for a good while and you should have no
+plans in vanishing in the near future.
+
+We do not make the list of participants public mostly because it tends to vary
+somewhat over time and a list somewhere will only risk getting outdated.
