You're using a 1024 bit key here which seems a bit gutsy ;-) Without better attacks, you basically have: Brute force AES 256 -> O(2^256) Bruce force your 20 char password -> roughly O(2^(20*7)) == O(2^140) Factor your 1024 bit public modulus -> roughly O(2^80) Since a 768 bit RSA key has already been factored I'd say you only have a few years before a moderately sized cluster could factor your publickey.Of course, as I write this I realize I'm about to sign this message with a 1024 bit DSA key...Actually it's 2048, which I was comfortable with. And don't forget the 16bit salt on that password ;)
I stand corrected-that key was indeed 1024, not 2048. LSI still has some hope in cracking my key and getting that scan of my passport since I used "ancient encryption" after all! FWIW, v1.1.07 actually uses 4096 bit keys, which I will update shortly. Not sure if I'm going to make that configurable or not. I'm thinking no, because there's no real value in using a smaller key in this application. t _______________________________________________ Full-Disclosure - We believe in it.
