Somebody says:
Is security provided by 1024-bit PGP key sufficient against most powerful computers that are available today? Say if smoe organization spent 10 billions of dollars on a cracking machine, would it be possible to crack the keys in reasonable time?
Derek Atkins <warlord@MIT.EDU> responds with some useful and authoritative information -- thanks.
Also, remember that although the PGP key is 1024 bits, it generates a much smaller IDEA key with 56 bits (I think... anyone?). The 56 bit key is vunerable to that $1 mil mystery machine that the NSA may or may not have.
