            # Apache HTTP Server


            ##  What is it?


            The Apache HTTP Server is a powerful, flexible, HTTP/1.1 and HTTP/2 compliant, and widely deployed

            
            web server.  Originally designed as a replacement for the NCSA HTTP

            
            Server, it has been in continuous development since 1995 and remains

            
            one of the foundational projects of the Apache Software Foundation. The

            
            developers aim to collaboratively develop and maintain a robust,

            
            commercial-grade, standards-based server with freely available

            
            source code.


            ## The Latest Version


            Details of the latest version can be found on the [Apache HTTP

            
            server project page](https://httpd.apache.org/).

            ## Cryptographic Software Notice


            This distribution may include software that has been designed for use

            
            with cryptographic software.  The country in which you currently reside

            
            may have restrictions on the import, possession, use, and/or re-export

            
            to another country, of encryption software.  BEFORE using any encryption

            
            software, please check your country's laws, regulations and policies

            
            concerning the import, possession, or use, and re-export of encryption

            
            software, to see if this is permitted.  See

            
            [https://www.wassenaar.org/](https://www.wassenaar.org/)

            
            for more information.


            The U.S. Government Department of Commerce, Bureau of Industry and

            
            Security (BIS), has classified this software as Export Commodity

            
            Control Number (ECCN) 5D002.C.1, which includes information security

            
            software using or performing cryptographic functions with asymmetric

            
            algorithms.  The form and manner of this Apache Software Foundation

            
            distribution makes it eligible for export under the License Exception

            
            ENC Technology Software Unrestricted (TSU) exception (see the BIS

            
            Export Administration Regulations, Section 740.13) for both object

            
            code and source code.


            The following provides more details on the included files that

            
            may be subject to export controls on cryptographic software:


            Apache httpd 2.0 and later versions include the mod_ssl module under

            
            `modules/ssl/`

            
            for configuring and listening to connections over SSL encrypted

            
            network sockets by performing calls to a general-purpose encryption

            
            library, such as OpenSSL or the operating system's platform-specific

            
            SSL facilities.


            In addition, some versions of apr-util provide an abstract interface

            
            for symmetrical cryptographic functions that make use of a

            
            general-purpose encryption library, such as OpenSSL, NSS, or the

            
            operating system's platform-specific facilities. This interface is

            
            known as the `apr_crypto` interface, with implementation beneath the

            
            `/crypto` directory. The `apr_crypto` interface is used by the

            
            `mod_session_crypto` module available under

            
            `modules/session`

            
            for optional encryption of session information.


            Some object code distributions of Apache httpd, indicated with the

            
            word "crypto" in the package name, may include object code for the

            
            OpenSSL encryption library as distributed in open source form from

            
            [https://www.openssl.org/source/](https://www.openssl.org/source/).


            The above files are optional and may be removed if the cryptographic

            
            functionality is not desired or needs to be excluded from redistribution.

            
            Distribution packages of Apache httpd that include the word "nossl"

            
            in the package name have been created without the above files and are

            
            therefore not subject to this notice.

	Distribution packages of Apache httpd that include the word "nossl"
