[PROG] Questions about programming with OpenSSL
* Which is the current version of OpenSSL?
The current version is available from <URL: http://www.openssl.org>.
-OpenSSL 0.9.6d was released on May 9, 2002.
+OpenSSL 0.9.6h was released on December 5, 2002.
In addition to the current stable release, you can also access daily
snapshots of the OpenSSL development version at <URL:
version 0.9.7 (not yet released) the changes were merged into the main
development line, so that the special release is no longer necessary.
+* How do I check the authenticity of the OpenSSL distribution?
+
+We provide MD5 digests and ASC signatures of each tarball.
+Use MD5 to check that a tarball from a mirror site is identical:
+
+ md5sum TARBALL | awk '{print $1;}' | cmp - TARBALL.md5
+
+You can check authenticity using pgp or gpg. You need the OpenSSL team
+member public key used to sign it (download it from a key server). Then
+just do:
+
+ pgp TARBALL.asc

* Do I need patent licenses to use OpenSSL?

However, be warned that /dev/random is usually a blocking device, which
may have some effects on OpenSSL.

* Why do I get an "unable to write 'random state'" error message?
for download instructions) can be safely used, for example.
+* Why does the OpenSSL test fail with "bc: stack empty"?
+
+On some DG/ux versions, bc seems to have a too small stack for calculations
+that the OpenSSL bntest throws at it. This gets triggered when you run the
+test suite (using "make test"). The message returned is "bc: stack empty".
+
+The best way to deal with this is to find another implementation of bc
+and compile/install it. GNU bc (see http://www.gnu.org/software/software.html
+for download instructions) can be safely used, for example.

* Why does the OpenSSL compilation fail on Alpha Tru64 Unix?
On some Alpha installations running Tru64 Unix and Compaq C, the compilation

+* Why does the OpenSSL compilation fail on MacOS X?
+
+If the failure happens when trying to build the "openssl" binary, with
+a large number of undefined symbols, it's very probable that you have
+OpenSSL 0.9.6b delivered with the operating system (you can find out by
+running '/usr/bin/openssl version') and that you were trying to build
+OpenSSL 0.9.7 or newer. The problem is that the loader ('ld') in
+MacOS X has a misfeature that's quite difficult to go around.
+Look in the file PROBLEMS for a more detailed explanation and for possible
+solutions.

+
+* Why does the OpenSSL test suite fail on MacOS X?
+
+If the failure happens when running 'make test' and the RC4 test fails,
+it's very probable that you have OpenSSL 0.9.6b delivered with the
+operating system (you can find out by running '/usr/bin/openssl version')
+and that you were trying to build OpenSSL 0.9.6d. The problem is that
+the loader ('ld') in MacOS X has a misfeature that's quite difficult to
+go around and has linked the programs "openssl" and the test programs
+with /usr/lib/libcrypto.dylib and /usr/lib/libssl.dylib instead of the
+libraries you just built.
+Look in the file PROBLEMS for a more detailed explanation and for possible
+solutions.
