I don't think there exists such thing as a "standard format" in base58 that's < 51 characters. The standard base58 format is the sipa wallet import format. I also wouldn't offer it in base64 unless something else uses it prominently (e.g. OpenSSL, but OpenSSL uses hex). These unused formats will just serve to confuse people.
Also, hexadecimal is misspelled on the actual website.
LOL. I guess Standard Format didn't exist until MagicalTux created it... maybe I'm adding to the problem. I don't want to cause confusion. Mtgox still doesn't work with WIF. I added the base64 only because it was available in the .toString() method for the ECKey and I assumed Stephan had a reason for that. I'm going to double check Mtgox works with hex. Hopefully they fix the WIF bug soon. Did MtGox stop accepting in the "standard format"? Because I tried it a few days ago and it worked.

Cool. Another way to convert. I don't have a "mini-key" to test but if you put that in will it also give you the other formats? Yes, a little Easter Egg for Casascius ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)

MtGox only accepted that format because MagicalTux was confused as to how the format worked. Nothing generates keys in that format, and quite frankly there is no advantage to doing it because it takes away the error checking for no good reason. It would be best not to propagate new formats for keys that don't serve any particular purpose, otherwise everybody will have to support them for everything.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable. I never believe them. If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins. I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion. Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice. Don't keep coins online. Use paper or hardware wallets instead.

Is there any known reason why this does not work in mobile safari? The gen key function seems to be called and the CPU seems to be chugging along for 4-5s but nothing is displayed past "move your mouse". I tried to step through the js execution and think the script halted at one one of underlying crypto functions.
Try Opera Mini. It works on my iPod 2G.

Hopefully they fix the WIF bug soon. Did MtGox stop accepting in the "standard format"? Because I tried it a few days ago and it worked. I have verified that Mt. Gox works with and automatically detects both the mini private key format and the hex format. The last time I checked it still did not work with the "standard" WIF but I will check it again in a few days. I filed a bug report with Mt. Gox but they have not even assigned it to anyone yet, let alone gotten back to me.

Try Opera Mini. It works on my iPod 2G. I recommend that you DO NOT do use "Opera Mini". It is a different type of browser that uses a proxy and renders the information server side (including JavaScript execution results) then sends the results to the client. So theoretically Opera knows about any private keys generated using "Opera Mini". Opera has another mobile browser called "Opera Mobile" which is safe to use but may not solve the slow JavaScript issue on some iDevices.

I'm going to remove the "standard format" from the next release. I just checked and MtGox no longer accepts it. I agree the sipa format is better due to the error checking and the usability feature of always starting with a 5. I can also confirm that the hexadecimal format works at MtGox. Thanks bwagner for checking as well.

MagicalTux reports having fixed this. It now accepts Base58 private keys, and I was able to import one as a test.

I also wouldn't offer it in base64 unless something else uses it prominently (e.g. OpenSSL, but OpenSSL uses hex).
# write 32 random bytes of base64-encoded data to stdout $ openssl rand -base64 32 0kMS0ngFjbWFnDAQzH+OvJTlO2b6O71Kcv9aKpWVh2k=
Looks like you can generate random numbers in base64 with OpenSSL: http://www.madboa.com/geek/openssl/#random-generateI'm not sure who, if anyone, is using base64 but it's such a wide spread encoding I figured it would be useful to include in the tool.

A deterministic generation function does one more very valuable thing from an auditability perspective that has nothing to do with recreating wallets. Supporting deterministic generation from a passphrase allows the average user to control for the possibility that the RNG in your generator isn't rigged or flawed in a non-obvious manner. If your RNG turns out to be flawed at any time down the road, it would turn into a huge liability for anyone who has ever used your generator. (Google "Debian OpenSSL key flaw" for an example of a past occurrence of this mess). On the other hand, if it produces the same deterministic wallet as any other program made for the same purpose, it can be conclusively deemed to operate as advertised.
The Wallet Details tab can now be used for the purpose of creating a deterministic wallet. You can use the tab to determine if you have a valid private key in one of various formats and what the bitcoin address is for that key. It's also useful if you're in a highly adversarial environment and you believe a weakness in the PRNG could expose your private key. To protect against that you could copy the key you generate on the single wallet tab and paste it on the wallet details tab and adjust a few characters then view the details to confirm it's a valid private key and see it's bitcoin address.

I decided to open source the project, it's now available under an MIT License. https://github.com/pointbiz/bitaddress.orgI've uploaded the version history from v0.5 to the current v1.2 so it's easier to review the changes.

In my opinion, this should be available directly at places like bitcoin.org, weusecoins.com, mtgox.com, etc...

that's amazing ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Q: do you plan to add testnet switch for addresses/keys valid for testnet blockchain? p.s. pls send me a unique address for a bitcoin donation That is exciting news, and an enormous contribution to the community! Thanks much!

I would like a bitaddress option to generate a PDF of dollar bill sized print outs. What printcoins.com is doing works great because they fit in a wallet.

I'm having to pshop them manually. I'm not printing bill exactly, but a similar format. A DTP program would prolly do a better job.
