In December, it was reported that security firm RSA -- according to documents leaked by Edward Snowden -- was paid millions by the NSA to put a back door into its encryption products. A couple days later, the company denied having a secret contract with the government agency, and said that it never knowingly put a back door in its offerings. That didn't stop some companies from gravitating away from RSA, however, and one such company was Wickr. The company's founder, Nico Sell, announced this change at an RSA Security Conference, during which she made it clear her company would not have a back door and that users' security was important. Immediately after, an FBI agent approached her with a request -- to add a backdoor on behalf of the agency.
