* Which is the current version of OpenSSL?
The current version is available from <URL: http://www.openssl.org>.
-OpenSSL 0.9.8e was released on February 23rd, 2007.
+OpenSSL 0.9.8k was released on Mar 25th, 2009.
In addition to the current stable release, you can also access daily
snapshots of the OpenSSL development version at <URL:
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
+manpage. Documentation for developers is currently being written. Many
+manual pages 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/>.
+<URL: http://www.openssl.org/docs/>. Note that the online documents refer
+to the very latest development versions of OpenSSL and may include features
+not present in released versions. If in doubt refer to the documentation
+that came with the version of OpenSSL you are using.
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
name of C.
+* How can I set up a bundle of commercial root CA certificates?
+
+The OpenSSL software is shipped without any root CA certificate as the
+OpenSSL project does not have any policy on including or excluding
+any specific CA and does not intend to set up such a policy. Deciding
+about which CAs to support is up to application developers or
+administrators.
+
+Other projects do have other policies so you can for example extract the CA
+bundle used by Mozilla and/or modssl as described in this article:

[BUILD] =======================================================================
* Why does the linker complain about undefined symbols?
Multi-threaded applications must provide two callback functions to
OpenSSL by calling CRYPTO_set_locking_callback() and
-CRYPTO_set_id_callback(). (For OpenSSL 0.9.9 or later, the new
-function CRYPTO_set_idptr_callback() may be used in place of
-CRYPTO_set_id_callback().) This is described in the threads(3)
-manpage.
+CRYPTO_set_id_callback(), for all versions of OpenSSL up to and
+including 0.9.8[abc...]. As of version 0.9.9, CRYPTO_set_id_callback()
+and associated APIs are deprecated by CRYPTO_THREADID_set_callback()
+and friends. This is described in the threads(3) manpage.
* I've compiled a program under Windows and it crashes: why?
* Why do I get errors about unknown algorithms?
-This can happen under several circumstances such as reading in an
-encrypted private key or attempting to decrypt a PKCS#12 file. The cause
-is forgetting to load OpenSSL's table of algorithms with
-OpenSSL_add_all_algorithms(). See the manual page for more information.

+The cause is forgetting to load OpenSSL's table of algorithms with

+can cause several problems such as being unable to read in an encrypted

* Why can't the OpenSSH configure script detect OpenSSL?
See the manual pages for more details.
-===============================================================================
+* Where are the declarations and implementations of d2i_X509() etc?
+These are defined and implemented by macros of the form:
+
+
+ DECLARE_ASN1_FUNCTIONS(X509) and IMPLEMENT_ASN1_FUNCTIONS(X509)
+
+The implementation passes an ASN1 "template" defining the structure into an
+ASN1 interpreter using generalised functions such as ASN1_item_d2i().
