-
-OpenSSL is a library that provides cryptographic functionality to
-applications such as secure web servers. Be sure to read the
-documentation of the application you want to use. The INSTALL file
-explains how to install this library.
-
-OpenSSL includes a command line utility that can be used to perform a
-variety of cryptographic functions. It is described in the openssl(1)
-manpage. Documentation for developers is currently being written. A
-few manual pages already are available; overviews over libcrypto and
-libssl are given in the crypto(3) and ssl(3) manpages.
-
-The OpenSSL manpages are installed in /usr/local/ssl/man/ (or a
-different directory if you specified one as described in INSTALL).
-In addition, you can read the most current versions at
-<URL: http://www.openssl.org/docs/>.
-
-For information on parts of libcrypto that are not yet documented, you
-might want to read Ariel Glenn's documentation on SSLeay 0.9, OpenSSL's
-predecessor, at <URL: http://www.columbia.edu/~ariel/ssleay/>. Much
-of this still applies to OpenSSL.
-
-The original SSLeay documentation is included in OpenSSL as
-doc/ssleay.txt. It may be useful when none of the other ressources
-help, but please note that it reflects the obsolete version SSLeay
-0.6.6.
-
-
-* How can I contact the OpenSSL developers?
-
-The README file describes how to submit bug reports and patches to
-OpenSSL. Information on the OpenSSL mailing lists is available from
-<URL: http://www.openssl.org>.
-
-
-* Do I have to license patents to use OpenSSL?
-
-The patents section of the README file lists patents that may apply to
-you if you want to use OpenSSL. For information on intellectual
-property rights, please consult a lawyer. The OpenSSL team does not
-offer legal advice.
-
-You can configure OpenSSL so as not to use RC5 and IDEA by using
- ./config no-rc5 no-idea
-
-Until the RSA patent expires, U.S. users may want to use
- ./config no-rc5 no-idea no-rsa
-
-Please note that you will *not* be able to communicate with most of
-the popular web browsers without RSA support.
-
-
-* Is OpenSSL thread-safe?
-
-Yes. On Windows and many Unix systems, OpenSSL automatically uses the
-multi-threaded versions of the standard libraries. If your platform
-is not one of these, consult the INSTALL file.
-
-Multi-threaded applications must provide two callback functions to
-OpenSSL. This will be described in the threads(3) manpage. [That
-page has not been written yet. Please read the "threads.doc" section
-of doc/ssleay.txt instead.]
-
-
-* Why do I get a "PRNG not seeded" error message?
-
-Cryptographic software needs a source of unpredictable data to work
-correctly. Many open source operating systems provide a "randomness
-device" that serves this purpose. On other systems, applications have
-to call the RAND_add() or RAND_seed() function with appropriate data
-before generating keys or performing public key encryption.
-
-Some broken applications do not do this. As of version 0.9.5, the
-OpenSSL functions that need randomness report an error if the random
-number generator has not been seeded with at least 128 bits of
-randomness. If this error occurs, please contact the author of the
-application you are using. It is likely that it never worked
-correctly. OpenSSL 0.9.5 makes the error visible by refusing to
-perform potentially insecure encryption.
