RSA has responded to the allegations originally made by Edward Snowden's latest whistleblowing that the company had taken $10m for a backdoor into its crypto software.

In a strongly yet carefully worded blog post today, RSA said “we categorically deny [the] allegation” that it "entered into a 'secret contract' with the NSA to incorporate a known flawed random number generator".

Avoiding to discuss the $10m, the post concluded with the following statement:

“RSA, as a security company, never divulges details of customer engagements, but we also categorically state that we have never entered into any contract or engaged in any project with the intention of weakening RSA’s products, or introducing potential ‘backdoors’ into our products for anyone’s use.”

The Reuters writer who broke the original news on Friday, Joseph Menn, stands by his story.
