Golygydd Max writes "I didn't see much coverage of the RC4 flaw in Microsoft Office that was uncovered recently by a researcher, Hongjun Wu. Now, PGP creator Phil Zimmermann, dissatisfied with Microsoft's response, has joined in the debate. In an interview with Techworld he castigates Microsoft for their inadequate response: 'The lay user ought to be entitled to assume that the encryption produced by Microsoft is adequate. ... If Microsoft wants to earn the respect of the cryptographic community and the public it must rise to the occasion by producing competent security.' The cynic might ask, 'what respect', but should Microsoft have taken a flaw in some of its most popular programs more seriously?"
