 The OpenSSL Project is a collaborative effort to develop a robust,
 commercial-grade, fully featured, and Open Source toolkit implementing the
 Secure Sockets Layer (SSLv3) and Transport Layer Security (TLS) protocols as
 well as a full-strength general purpose cryptograpic library. The project is
 managed by a worldwide community of volunteers that use the Internet to
 communicate, plan, and develop the OpenSSL toolkit and its related

 OpenSSL is descended from the SSLeay library developed by Eric A. Young
 and Tim J. Hudson.  The OpenSSL toolkit is licensed under a dual-license (the
 OpenSSL license plus the SSLeay license), which means that you are free to
 get and use it for commercial and non-commercial purposes as long as you
 fulfill the conditions of both licenses.


 The OpenSSL toolkit includes:

     Provides the client and server-side implementations for SSLv3 and TLS.

     Provides general cryptographic and X.509 support needed by SSL/TLS but
     not logically part of it.

     A command line tool that can be used for:
        Creation of key parameters
        Creation of X.509 certificates, CSRs and CRLs
        Calculation of message digests
        Encryption and decryption
        SSL/TLS client and server tests
        Handling of S/MIME signed or encrypted mail
        And more...

 If you have any problems with OpenSSL then please take the following steps

    - Download the current snapshot from
      to see if the problem has already been addressed
    - Remove ASM versions of libraries
    - Remove compiler optimisation flags

 If you wish to report a bug then please include the following information in
 any bug report:

    - On Unix systems:
        Self-test report generated by 'make report'
    - On other systems:
        OpenSSL version: output of 'openssl version -a'
        OS Name, Version, Hardware platform
        Compiler Details (name, version)
    - Application Details (name, version)
    - Problem Description (steps that will reproduce the problem, if known)
    - Stack Traceback (if the application dumps core)

 Email the report to:

 In order to avoid spam, this is a moderated mailing list, and it might
 take a day for the ticket to show up.  (We also scan posts to make sure
 that security disclosures aren't publically posted by mistake.) Mail
 to this address is recorded in the public RT (request tracker) database
 (see for details) and
 also forwarded the public openssl-dev mailing list.  Confidential mail
 may be sent to (PGP key available from the
 key servers).

 Please do NOT use this for general assistance or support queries.
 Just because something doesn't work the way you expect does not mean it
 is necessarily a bug in OpenSSL.

 You can also make GitHub pull requests. If you do this, please also send
 mail to with a link to the PR so that we can more easily
 keep track of it.




 A number of nations, in particular the U.S., restrict the use or export
 of cryptography. If you are potentially subject to such restrictions
 you should seek competent professional legal advice before attempting to
 develop or distribute cryptographic code.
