2^32 = 4,294,967,296 or almost 4.3 billion, therefore breaking a DigiCert 2048-bit SSL certificate would take about 4.3 billion times longer (using the same standard desktop processing) than doing it for a 1024-bit keySignificance[edit]The effectiveness of public key cryptosystems depends on the intractability (computational and theoretical) of certain mathematical problems such as integer factorizationSoghoian says that the the kind of stuff we need is already available, its just not in our browsers and not with Google and Facebook= 2048 12-bit 2^12 2x2x2x2x2x2x2x2x2x2 Again, it would take significantly longer than the age of the universe to crack a 128-bit keyAs of 2015, NIST guidance says that "the use of keys that provide less than 112 bits of security strength for key agreement is now disallowed." NIST approved symmetric encryption algorithms include three-key Triple DES, and AESDrake said that he was certain that Skype has been compromisedOf course the argument is that computers will keep getting faster, about doubling in power every 18 months

SSL Certificate Code Signing Security Solutions Support Partners About Us The Math Behind Estimations to Break a 2048-bit Certificate The Math: So youre interested in the math/science behind our claims in the SSL cracking video.? This is the basis of our assumptionsEither way, your data is still encrypted and still secureR.; Bennett, CTrying all "potential" passwords, i.eet alexpects to gain full unencrypted access to an unnamed major Internet phone call and text service sometime this yearhas circumvented common Web encryption primarily by cheating, not by mathematics"Minimal key lengths for symmetric ciphers to provide adequate commercial security"On the other hand, there are much fewer potential passwords because passwords are chosen by humans with human brains, and human brains are not good at making random choices; also, humans are lazy and will prefer short passwords (easier to remember, easier to type in)Of course, even this 'vulnerability' is not really applicable to applications like an online credit card transaction, since the transaction is completed in a few momentsAs we transmit the information to the Bank's Secure SSL Server, they require a 128-bit transaction and will not process a transaction without oneMatt Buchanan was a science and technology editor for newyorker.com from 2013 to 2014elliptic curve cryptography)SSL Certificate Code Signing Security Solutions Support Partners About Us What Would it Take to Break a 2048 Bit SSL Certificate? Don't have the patience to sit through that whole minute and twenty seconds? Just check out the timeline, below, for a static-representation of the data shown in the video2^40 is already a HUGE number, about a trillion (that's a million, million!)Many ciphers are actually based on publicly known algorithms or are open source and so it is only the difficulty of obtaining the key that determines security of the system, provided that there is no analytic attack (i.e., a 'structural weakness' in the algorithms or protocols used), and assuming that the key is not otherwise available (such as via theft, extortion, or compromise of computer systems)Toad.comRetrieved 14 October 2011 5d555b9bac
