I’m wondering why you need the log function?
If you’re measuring performance, could the analysis tool perform the logarithm?
A first order approximation to log_2(n) where n is a BIGNUM would be
BN_num_bits(n).

Or scale the large number so it fits and add the log of the scale factor which
you can compute by hand from the scale factor. For examp

Negative. We use the following method:

no-hw \
no-zl
log() in math.h only supports float or double type. float and double are
limited in the range of numbers they can express. For example, these types
cannot hold large numbers like "9".
Depending on your purpose, float and double may be sufficient, and you can
Thank you for the answer. We are using the Makefile from OpenSSL to
compile our feature as it changes OpenSSL directly. As I understood it,
we would have to import another number library to compile our code with
the standard OpenSSL settings and using the logarithm, correct?

If you want to use the log() from math.h, then you must compile with -lm,
eg.: clang source.c -lm
The log() in math.h only supports floating point numbers. If you require
computing logarithms of bignums, try https://www.mpfr.org/

Hello,
we are implementing a TLS 1.3 feature into OpenSSL to get an idea of how
well our feature performs in a concrete server library. In the feature,
we want to use the log function.
When we try to use the log function from the math.h header, OpenSSL
won't compile with the statement that '
Hi Michael Mueller
Thank you for answering. So if I understand you correctly you also use the
"build.info" file to specify the static libraries as dependencies for the
'openssl' binary.
Do you encounter any segmentation faults when running the tests provided by
OpenSSL in the openssl/test/recipe
Hi Matt,
Thanks for the thumbs-up. I can confirm that it works as expected. If I cast
away the const and call RSA_set_ex_data() then the session handle is updated
and available the next time stunnel uses that same key.
Now I just need to figure out how to document this so that a potential cod
