In some cases, the NSA was back-channeling with the international agencies that set the cryptographic standards adopted by security companies and their clients. In at least one case, the NSA successfully convinced Canadian bureaucrats to advocate for a flawed formula for generating the random numbers in encryption schemes that NSA computers could easily crack. The agency was even paying major American security companies, like RSA, to make its flawed formula for generating random numbers the default encryption method for widely used security products.
