Look at this file instead. This utility makes it easy to deal with Bitcoin private keys and addresses in their native and various intermediate formats. You can see from blockchain. Of course, neither has any funds in it well, at least not at this time , since draining the funds is as simple as entering one of the WIF values above into a Bitcoin client. The corresponding WIF "wallet import format" key is displayed, both in compressed and uncompressed format; with this information, you can import the corresponding bitcoin address into your client.
Note that the WIF simply contains the exponent encoded using "hashed base 58". The "hashed base 58" encoding is used to represent an integer with a checksum for validity. A bit checksum is appended to the binary form of the integer, forming another integer. This integer is then represented in base 58 using the alphabet of all digits and all letters of the upper and lower case English alphabet except 0, o, O and l presumably left out because of potential confusion.
So encoding the WIF in this format really provides no additional non-redundant information beyond the secret exponent. The public pair x and y correspond to the ECDSA elliptical curve digital signature algorithm public key that is used to verify digital signatures. Bitcoin clients use public keys to validate that transactions are signed by an entity that has knowledge of the corresponding secret exponent.
The x, y value is on the elliptical curve used by bitcoin. Since P is odd, exactly one of y0 and y1 is even, and the other is odd. In other words, with x and knowledge of whether y is even or odd, we can figure out the value for y. This is how compressed keys work This is the internal format that Bitcoin uses in transaction signatures to encode public keys. There is an uncompressed format, which has a prefix of a single 04 byte, followed by the x and y coordinates, and a compressed format, which has a prefix of 02 or 03 depending upon whether the y coordinate is even or odd, followed by the x coordinate.
The hash value is the ripemd hash of the sha hash of the bytestream of the sec version of the key. The bu utility will accept input in nearly any format, automatically determining the input type, and display output of all values that can calculated. Obviously if you enter a Bitcoin address, you won't get the corresponding WIF! The input here is determined to be a Bitcoin address. The only thing that it can be converted to is a hash Let's try one more example using the WIF from https: The code seems really cleanly written and the BIP implementation is very useful.
Thinking out loud here… it seems creating an M-of-N transaction would be simple… just fill in a template script in the TxOut. So doing this would be a bit of work, since a partial transaction would have to be created. Are there any M-of-N transactions in the blockchain? It seems there must be. Finding one would be a good first step. How do you propose people make wallets, do we really want pure random or could someone make a WIF based on the sha of a very good passphrase?
In your failure case, your secret exponent is 0, which is invalid. The secret exponent has to be an integer between 1 and Found an M of N transaction: The platform allows coins to be sent to BlackHoles: My question is how do we turn your genwallet tool and a BIP32 web client without using the wallet. I can maybe make virtual environments when the webclient logs in. Sorry just throwing some questions out. I want to build a safe BIP32 web wallet for the masses, without storing the private keys.
No private Key — No coins — The world needs a safe wallet help. You might find this thread interesting unless you are already posting in it! Hi Richard, Having issues installing Python newb here … Downloaded Pycoin from github as a zip, uninstalled contents into folder C: Your tool looks fantastic and would love to try it out so any help greatly appreciated.
Your email address will not be published. There is a bunch of information here. The secret exponent is displayed in decimal and in hex. In this last case nothing needs to be stored in order to be able to access the bitcoins. BIP makes this easier, yes. Is there any documentation for this utility? What do the various breakdown of the keys represent, step by step? How to store your bitcoins Start Using Bitcoin.
