Title: excel file to make public bitcoin address Post by: altcointalk14 on January 28, 2016, 08:02:28 PM Hello,
Has anyone found an excel spreadsheet that you can enter your string of 256 ones & zeros and it would spit out the HEX format and the public address? Title: Re: excel file to make public bitcoin address Post by: DannyHamilton on January 29, 2016, 02:08:29 AM Not aware of an Excel spreadsheet to do that, but I did write a simple C program that generates addresses from a WIF private key. It would be pretty simple to modify the program to work with 256 ones & zeros instead of a WIF key

BIN2DEC() only supports 10 bits. HEX2DEC() only supports 40 bits. even n = 115792089237316195423570985008687907852837564279074904382605163141518161494337 pasted into a cell: 1.15792089237316E+77 This guy made a spreadsheet that does SHA256 of some text, which is already impressive. It has about 80 sheets of formulas. https://bitcointalk.org/index.php?topic=809430.0 |
