libssh2 - SSH2 library

======================

libssh2 is a library implementing the SSH2 protocol, available under

the revised BSD license.

Web site: http://www.libssh2.org/

Mailing list: http://cool.haxx.se/mailman/listinfo/libssh2-devel

Generic installation instructions are in INSTALL.  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).
