Re: Until key length equals...
Oh yes. And just how do you distribute said one-time pads securely to the world+dog for use?
That is the point of practical cryptography, to make stuff "secure enough" while still being practical to use from a key management and encoding/decoding effort point of view. If you run a web server with limited resources, you don't really relish everyone going to 16k key lengths for access to videos of cats, etc.
Even with 128 bit keys, if implemented properly and used by all, the effort of breaking it would overwhelm the TLAs. That is why they sought to get the private keys by other means. Of course, if targeted by a gov or major criminal organisation so a lot of resources can be target at only your messages then 128 bits is clearly not enough, but you need to put usage in to perspective.
