Steve Gibson details on a Security Now podcast in his usual expert and friendly manner how NSA did indeed weaken a NIST cryptographic standard. Fortunately, that particular standard is so lame and slow it is virtually never used. Happily, the Snowden Effect is forcing reexamination of all crypto methods and stronger and better methods no doubt are coming.
If you use LasPass for passwords (I do), you are safe, explains Gibson. Laspass does not store keys on its servers and thus NSA can’t force them to give up anything. Futher, LastPass says if anything like that ever happened they would simply shut down.
