The confidence in AES comes from its designation process during which many publicly tried and failed to convincingly reduce its security claim and the fact that it has (publicly still) stood the test of time : ten years later all we have are the bicliques which gains us 2 bits. It doesn't have

So the practical reason behind everyone saying unless you have qualifications, etc, don't do this is because, even if you make something and say it's just for your learning or a joke or w/e, someone (no joke) *will* use it and then some Fortune 500 will fall over because of your joke code. So,

If it's so foolish to build your own crypto, how foolish would a Fortune 500 company be to deploy it? Too bad there's not a crypto hacker service to test out various crypto algorithms. We're always told to trust the government-sponsored crypto like AES when we know full well that governments

Just use XXTEA. It's the only good cipher that allows for blocks of size equal to that of a disk sector. Additionally, maybe use XXTEA in CTR mode to provide additional confidentiality so that blocks with all zeroes won't output to the same value. On Tue, Jan 6, 2015 at 1:12 PM, Kevin

The source code is mostly written to the OpenSSL coding standards, which are seriously different from any other coding standard I've seen (it's not Linux/KR, nor GNU, nor Microsoft, nor Sun/Oracle). Nonconformance with the coding standards in later patches is very common, so it's a mishmash
