Hi, I'm just curious.
Would you buy hard drives (up to 2TB) with rainbow tables(lm, ntlm, md5, sha1, ...) on it ?

Unlike traditional banking where clients have only a few account numbers, with Bitcoin people can create an unlimited number of accounts (addresses). This can be used to easily track payments, and it improves anonymity.

Do you have sha256?  |

Do you have sha256? Won't really help you riX, if you want them I can generate 64 GB in a week and charge you 50 BTC + the thumb drive. |

I might if you have the A5/1 tables  http://reflextor.com/e100torrents/Metered internet sucks balls. I've already gone over my monthly quota, so my 100Mbit/s fiber is throttled to 64Kbit/s. |

This is why brcypt was created, to make rainbow table attacks more difficult. And if a salt is used then it's pretty computationally expensive as well as time expensive.
Remember boys and girls, always use bcrypt + salt for all your password hashing needs.

Actually, I believe this is outdated advice. My understanding of best practice is to use HMAC. Here's the link to a stack overflow question that I recently read: http://stackoverflow.com/questions/401656/secure-hash-and-salt-for-php-passwords/401684#401684 |
