"Recent press coverage has asserted that RSA entered into a "secret contract" with the NSA to incorporate a known flawed random number generator into its BSAFE encryption libraries. We categorically deny this allegation."
"We have never entered into any contract or engaged in any project with the intention of weakening RSA's products" the company said.
"We made the decision to use Dual EC DRBG as the default in the BSAFE tool-kit in 2004, in the context of an industry-wide effort to develop newer, stronger methods of encryption. At that time, the NSA had a trusted role in the community-wide effort to strengthen, not weaken, encryption."
"The Dual EC DRBG was one of several different random number generators available and the customers was free to choose whichever one best suited their needs" RSA said.
Finally, in 2013 on National Institute of Standards and Technology (NIST) recommendations, RSA warned its customers not to use the algorithm at all.
