Adele Posted November 3, 2015 Share Posted November 3, 2015 (edited) Hello. I want to do threefish encrytion / decryption operations with AutoIt. There are implementations for languages like C#, Assembly but I don't know how can I use these with Autoit. I guess we can use DLLs for this and I wait for your help. If I want so much thing, I'm sorry because I don't have an idea about that how difficult. Maybe there is already an existing made function for Autoit. I've found some examples with Autoit but none is for Threefish.If you ask why do I want to use this algorithm, because supported algorithms on AutoIt like DES, RC, AES has some various bugs as I explored. Do you have a strong algorithm suggestion?Thank you in advance. Edited November 3, 2015 by Adele Threefish is the newest version replacing Twofish.

BrewManNH Posted November 3, 2015 Share Posted November 3, 2015 (edited) AES Rijndael is the standard, Twofish was one of the contenders for AES but lost out to Rijndael, so I'd be looking at the standard rather than the runner up myself.

spudw2k Posted November 3, 2015 Share Posted November 3, 2015 I would echo what BrewMan said...but I am curious......supported algorithms on AutoIt like DES, RC, AES has some various bugs as I explored.Can you elaborate?

Adele Posted November 3, 2015 Author Share Posted November 3, 2015 (edited) I've read non-English articles about this topic, so I can't share these here :). If you research on search engines, for example like "des rainbow" or "des cracking", you can find detailed articles and news. There are also informations on Wikipedia about that.Of course this doesn't mean these algorithms has been cracked completely. For example, before rainbow table of DES has been cracked, 2^56 (quadrillion) complexity was needed. But today DES can be crack with 2^39 (billion) complexity. So DES no longer can be crack in a very short time with supercomputers. Similarly, AES and RC can also be crack in shorter time using rainbow tables.

BrewManNH Posted November 3, 2015 Share Posted November 3, 2015 Every encryption can be cracked that way. The problem is that the rainbow tables needed for cracking AES needs more storage space than the entire internet currently has available. You're worried over nothing. Also what makes Twofish any better in this? Adele 1 If I posted any code, assume that code was written using the latest release version unless stated otherwise.

Adele Posted November 3, 2015 Author Share Posted November 3, 2015 (edited) You may be right. I've thought Twofish is safer because its rainbow tables haven't been cracked yet. I don't protect classified information but I always want best of everything.AES 128 seems like the safest algorithm on AutoIt and it has 2^126 complexity for now. Should I use this?

spudw2k Posted November 3, 2015 Share Posted November 3, 2015 (edited) Rainbow tables typically deal with hashing algorithms, not encryption. They are generated by producing all possible hashes using a character set definition (alphanum, special char, and length) in a brute-force manner. Still, yes...there are other cryptanalysis findings for DES, RC and AES, but nothing that completely breaks the algorithms, rendering them insecure.AutoIt supports Triple-DES, AES128, AES192 and AES256. I'd say any of those are reasonably safe to use.

Adele Posted November 3, 2015 Author Share Posted November 3, 2015 One more question... Is complexity value everything? Because AES 128 is older but has 2^126 complexity. AES 192 and 256 are newer despite that if I've understood correctly their complexities are 2^176 and 2^99. But I'm guessing that when rainbow tables were used (or whatever to decrease the complexity), the complexity decreases but the attack needs more time. In this case we can't say AES 256 is more insecure because it has 2^99 complexity according to AES 128.I wouldn't to talk more about this topic ...

iamtheky Posted November 3, 2015 Share Posted November 3, 2015 (edited) The only thing you are buying is time, and time is cheap. Does it matter if it takes the attacker 65 years to break it if you only need it locked down for .65 seconds? RC4 is still used widely because things like compatibility and CPU overhead matter more than enhancing the encryption. So endgame and sensitivity matter. AES Rijndael is the standard, Twofish was one of the contenders for AES but lost out to Rijndael, so I'd be looking at the standard rather than the runner up myself.The US Government uses ONLY unpublished algorithms for Compartmentalized TS and Suite A communications. And if the government gets it's shit from the right, and tells the people to get their shit from the left, the people should tell the government to gtfo. And experts/authors question the contest and results, so much so that some very smart security-minded folk are also going Two/ThreeFish.https://threatpost.com/silent-circle-moving-away-from-nist-ciphers-in-wake-of-nsa-revelations/102452/ Edited November 3, 2015 by boththose lacking a preposition Adele 1 ,-. .--. ________ .-. .-. ,---. ,-. .-. .-. .-. |(| / /\ \ |\ /| |__ __||| | | || .-' | |/ / \ \_/ )/ (_) / /__\ \ |(\ / | )| | | `-' | | `-. | | / __ \ (_) | | | __ | (_)\/ | (_) | | .-. | | .-' | | \ |__| ) ( | | | | |)| | \ / | | | | | |)| | `--. | |) \ | | `-' |_| (_) | |\/| | `-' /( (_)/( __.' |((_)-' /(_| '-' '-' (__) (__) (_) (__) Link to comment Share on other sites More sharing options...
