What is it ?
This is a proof of concept over the Dual_ec_drbg backdoor from NSA. It proves that
manipulating only one of the constants is enough to predict output from PRNG.
How to compile
Get the git version of FIPS openssl
git clone git://
cd openssl
git branch fips 4089bd6080d41450adab1e0ac0d63cfeab4a78e7
git checkout fips
git am ../0001-Test-enable-debugging-include-bn-functions-in-FIPS-b.patch
./config fipscanisteronly
If there's something that doesn't compile here... good luck. Do not attempt compiling regular libcrypto together with FIPS, it's not going to work.
