This program exhibits the backdoor behaviour of PRNG Dual_Ec_Drbg
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://git.openssl.org/openssl.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 make
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.
cd .. make ./dual_ec_drbg_poc
