Yep. I'm really hopeful that this will result in some good marketing avenues for my apps. Here's hoping!

OK here's my code, any issues with it anyone can see? #import <CommonCrypto/CommonKeyDerivation.h> ... // Makes a random 256-bit salt - (NSData*)generateSalt256 { unsigned char salt[32]; for (int

Thanks a lot! Very helpful. I'll use that then, since it's part of openssl - then i can claim rightly that i use industry standard crypto, rather than my bcrypt/sha256 mashup that i dreamt up myself.

Sounds like OpenSSL's 'PKCS5_PBKDF2_HMAC_SHA1' is the 'officially standard' way to make a key from a password, am i on the right track?
425.
by chubs 15y ago
Thankyou for the helpful reply. I'll look into the PBKDF2 approach. Which would be better, the first or second one you described? And what is the 'common implementation bug' in bcrypt you described, so i can look out for it?

I think this big picture 'losing ecommerce' is missing some nuanced analysis, that in my experience is actually more interesting: * I've had a better time with facebook ads than google ads, in terms of price and targeting * A lot of tiny bu

You know, i think you're right - if we use different salts for each emails/phones, there'd be no way of ensuring that different users use the same salts, or even if we stored the salt along with the hash, it wouldn't be much use. Hmm this i

Again: you're right in the case of SHA1, but rainbow tables don't apply to bcrypt because of the varying work factor, also you can use a different salt for each person. Crypto is actually really cool these days, there's pretty much a soluti

You're right in the case of SHA1. However, with a suitable work factor, you can't bruteforce bcrypt AFAIK

What if your address book was hashed (sha1, bcrypt) and then uploaded? In that case, all that would be uploaded is a list of hashes for the email addresses or phone numbers of people i know. Then, when another person signs up for an account

I feel like thomas edison after trying yet another filament: I have not failed. I've just found 10,000 ways that won't work. Here's hoping that sooner or later, i'll find some marketing ideas that work. Any suggestions appreciated from the

What a weird coincidence. This morning I was feeling inspired and wrote a blog on the exact same topic. Would it be spammy to put a link here? Anyway i love this kind of thinking, it really has helped my marriage a lot.

Looks fantastic, all i can say is: bigger fonts please, and don't give up finishing it! The world needs something better than w3schools, but simpler than MDN. You could be that.

Here's an easy way to get started networking in your local area: http://blog.asmartbear.com/cold-calling.html Basically the gist of it is to offer people something simple for free, to build relationships.

I had a quick look, but it didn't work on my iphone. I'd be really stoked if it was basically like google reader but had really nice typography - really that's all i want.

Keep up the good work. Wow - i just read all the comments here - there's a lot of 'can't be done' negativity. All that means is that you'll have few competitors. To be honest, i'm thinking of not bothering reading HN comments any more. Keep

That looks absolutely brilliant. So is the database all stored in the GPU memory? Or in main memory? Or does your engine handle storing to disk as well? Pretty novel use of a GPU though, and if it's quick, it could be really useful.

It sounds to me like enterprisey dropbox: It backs up your files from your local file server to the aws cloud, and if your server dies, bung in a new one and all your files will reappear. Great idea, although maybe something you could alrea

If you're still giving them away, i'd love to give your how-to a try. I've made 10 apps so far, they're all handy utilities i thought would be useful, and when i speak to people about them most people agree they sound useful, but i struggle

I think you've also got a good headstart with your wife already being in that industry. Clever marketing. That's my next mountain, so to speak: how to market my apps. Still scratching my head on that one.

Thanks for posting that. I'm in a similar situation with a couple of apps that have done surprisingly well, and am hoping to replicate their success on other apps. I especially like your marketing idea: qr codes on business cards handed out

I just had a look at leanpub for a friend whos about to start writing a book, it looks fantastic! I love the idea of writing markdown files into a dropbox folder, that sounds like a workflow made in heaven to me.

That's the way i implemented it in an iphone app i recently made: a 'sync now' button to pull anything new and push any updates to the server. Works quite well - I recently deleted my app (iphone died) and reinstalled it, one 'sync now' lat

Don't most people with high-traffic blogs simply use posterous or tumblr these days so they don't have to worry about these kinds of things? That's what works for me... then the next problem rears its ugly head: bulletproofing your DNS!

Argh! It's always the same story with most of my apps: Usually people say 'thats a great idea, i'd totally buy that', but without marketing, nobody knows about them. And so they sit, gathering virtual dust on the shelves of the app store. I

(OP here) Yup, that's the app - surprised you found it! Hmm... If you think all it needs is a visual makeover and some marketing, how about I give you the source code and remove my version from the app store, and you can make it over and se
