-
-		The SSH2 Transport also allows implementations to

+	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.
+
+
+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.
+
+
+2) HMAC
+
+libssh2_hmac_ctx
+Type of an HMAC computation context. Generally a struct.
+Used for all hash algorithms.
+
+void libssh2_hmac_ctx_init(libssh2_hmac_ctx ctx);
+Initializes the HMAC computation context ctx.
+Called before setting-up the hash algorithm.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_hmac_update(libssh2_hmac_ctx ctx,
+	                 const unsigned char *data,
+	                 int datalen);
+Continue computation of an HMAC on datalen bytes at data using context ctx.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_hmac_final(libssh2_hmac_ctx ctx,
+	                unsigned char output[]);
+Get the computed HMAC from context ctx into the output buffer. The
+minimum data buffer size depends on the HMAC hash algorithm.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_hmac_cleanup(libssh2_hmac_ctx *ctx);
+Releases the HMAC computation context at ctx.
+
+
+3) Hash algorithms.
+
+3.1) SHA-1
+Must always be implemented.
+
+SHA_DIGEST_LENGTH
+#define to 20, the SHA-1 digest length.
+
+libssh2_sha1_ctx
+Type of an SHA1 computation context. Generally a struct.
+
+int libssh2_sha1_init(libssh2_sha1_ctx *x);
+Initializes the SHA-1 computation context at x.
+Returns 1 for success and 0 for failure
+
+void libssh2_sha1_update(libssh2_sha1_ctx ctx,
+	                 const unsigned char *data,
+	                 size_t len);
+Continue computation of SHA-1 on len bytes at data using context ctx.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_sha1_final(libssh2_sha1_ctx ctx,
+                        unsigned char output[SHA1_DIGEST_LEN]);
+Get the computed SHA-1 signature from context ctx and store it into the
+output buffer.
+Release the context.
+Note: if the ctx parameter is modified by the underlying code,
+this procedure must be implemented as a macro to map ctx --> &ctx.
+
+void libssh2_hmac_sha1_init(libssh2_hmac_ctx *ctx,
+	                    const void *key,
+	                    int keylen);
+Setup the HMAC computation context ctx for an HMAC-SHA-1 computation using the
+keylen-byte key. Is invoked just after libssh2_hmac_ctx_init().
+
+3.2) SHA-256
+Must always be implemented.
+
+SHA256_DIGEST_LENGTH
+#define to 32, the SHA-256 digest length.
+
+libssh2_sha256_ctx
+Type of an SHA-256 computation context. Generally a struct.
+
+int libssh2_sha256_init(libssh2_sha256_ctx *x);
+Initializes the SHA-256 computation context at x.
+Returns 1 for success and 0 for failure
+

+More configure options
+======================
+
+Some ./configure options deserve additional comments:
+
+ * --enable-crypt-none
+
+	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
+
+	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.
+
+	If your installation of Libgcrypt is in another
+	location, specify it using --with-libgcrypt-prefix.
+
+ * --with-openssl
+ * --without-openssl
+ * --with-libssl-prefix=[DIR]
+
+	libssh2 can use the OpenSSL library
+	(http://www.openssl.org) for cryptographic operations.
+	Either Libgcrypt or OpenSSL is required.
+
+	Configure will attempt to locate OpenSSL in the
+	default location.
+
+	If your installation of OpenSSL is in another
+	location, specify it using --with-libssl-prefix.
+
+ * --with-libz
+ * --without-libz
+ * --with-libz-prefix=[DIR]
+
+	If present, libssh2 will attempt to use the zlib
+	(http://www.zlib.org) for payload compression, however
+	zlib is not required.
+
+	If your installation of Libz is in another location,
+	specify it using --with-libz-prefix.
+
+ * --enable-debug
+
+	Will make the build use more pedantic and strict compiler
+	options as well as enable the libssh2_trace() function (for
+	showing debug traces).

+
+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
+
+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:
+
+ * `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` (http://www.openssl.org),
+    `Libgcrypt` (http://www.gnupg.org/), `WinCNG` (Windows Vista+) 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.
+
+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 "")
