Very nice.  Posting to follow this thread... |

This page contains a serious flaw. It may well be true that padding increases the strength of your password, but if an attacker cracks one of your passwords, he will know what padding to use for your other passwords. That's true, if a password is cracked, and a human examines it. But if your password is something like 15 characters, it will take centuries to crack, so it won't be your problem if anyone ever succeeds. |

2. If you can remember your password, it is probably weak.
This actually isn't true, though one might think so. See new reasearch by Steve Gibson: https://www.grc.com/haystack.htm"research"? That is more like a very weak and naive claim. Old man seems to be getting way behind the curve. With all due respect, to Steve Gibson and his cute idea of easy to remember passwords, I am going to have to disagree with him on this. He claims that 'D0g.....................' is stronger password than 'PrXyc.N(n4k77#L!eVdAfp9'. He should know better. It might be the case when stupid brute force is employed, but these days attackers use much much more effective ways to reduce the key space than simply iterating over all permutations, as Steve seems to believe. These include permutations of dictionary words with common replacements of letters by numbers with various uppercase/lowercase scenarios in combination with sets of same symbols repeating as well as other methods of reducing keyspace by emulating various patterns people use to create passwords they can remember. These techniques often reduce keyspace by many orders of magnitude. Read the page again. The point is not that everyone should use passwords that's a dictionary word followed by repeating the same character X times, the point is that entropy is overrated, and a longer and memorable password is stronger than a shorter and impossible-to-remember one. |

Or are both blockchains kept in the same file, I wonder?
I have run both blockchains from an ubuntu install and only see a single wallet.dat file in my /.bitcoin folder.
The testnet data is in a subdirectory, cleverly disguised under the name "testnet".  |

2. Win32 .zip archive added.
Good, please link to it from www.bitcoin.org also. |

Well I just logged in now and changed my password to 20 characters with symbols etc, and do not have it stored on my computer but I have to still write it down on paper, because there is no way I will be able to memorize it.

If you're on Windows, the wallet is in %AppData%\Bitcoin\.

Very cool! I have been meaning to try this program, nice to hear that it actually works.  |

If you don't want to use a password manager, write down part of your password but keep a portion of it just in your head.

Yes let's not forget the time he bring out the first exchanger
No he didn't, he bought it from the guy who did. |

One of my friends got hacked on mybitcoin.com. He used the self username/password combination as on mtgox.
However his password was salt-hashed in the mtgox database, and far as I know its impossible to hack a salted hashvalue without the special salt hash/hex key.
*facepalm* No, the salt is right there in the file, next to the hash. What the salt does is make it impractical to use precomputed tables, you have to brute force the password. If the password is very weak this does not take long. |

".bit" is not set in stone, Namecoin can use a different TLD if needed. In fact, it could use several simultaneously. The TLD is not included in the names you register with Namecoin, it's just a resolver thing.
