Actually you can make more complex rules, but more complex the rule is, more computing power and time are necessary. And for some rules you may have to code yourself. Edit: this may be of help: Vanitygen can search for simple prefixes or regular expression matches. Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, vanitygen will ensure that the prefix is possible, and will provide a difficulty estimate. Exact prefixes are case-sensitive by default, but may be searched case-insensitively using the -i option. Prefixes are also very fast to search, and a list of thousands of prefixes may be specified with little or no reduction in key search rate. Regular expressions are programmable pattern filters. They are very powerful, and can be used to match prefixes, suffixes, varying-length sequences, etc.. For a quick tutorial, see http://www.regular-expressions.info/quickstart.html (http://www.regular-expressions.info/quickstart.html). To enable regular expressions, use the -r command line option. Unfortunately, regular expressions are very slow, and will have a significant impact on key search rate. Because of this, regular expressions should only be used if their expressive power is needed.

Title: Re: Generate an address with certain letters Post by: ABCbits on July 09, 2019, 05:22:38 PM I can't do it precisely if I remove letters from the base58 bitcoin addresses are invalid If you meant Bitcoin address with shorter length (shorter than 26), then it's impossible. See https://en.bitcoin.it/wiki/Address#What.27s_in_an_address (https://en.bitcoin.it/wiki/Address#What.27s_in_an_address) Quote ex: 15nE3ebnYkJYRok2H9H9Xdw1widwPtYt7TD4 You're going to have to limit the prefix length, or it will take forever to create. Also, lower case "o" isn't allowed.1E3en5widwbn.......... 1onbwE53................ According to https://en.bitcoin.it/wiki/Base58Check_encoding#Base58_symbol_chart (https://en.bitcoin.it/wiki/Base58Check_encoding#Base58_symbol_chart), lower case "o" is allowed, characters which aren't allowed are 0 (zero), O (upper case "o"), I (upper case "i"), and l (lower case "L") Title: Re: Generate an address with certain letters Post by: Thirdspace on July 09, 2019, 11:55:40 PM I can't do it precisely if I remove letters from the base58 bitcoin addresses are invalid what do you mean by that? you can't just simply remove/change a letter and expect it still a valid address no pattern but address with certain letter or base 58 - 10 characters as said before, regex (regular expression) will do the job you can use regex to choose only certain alphabet letters or numbers, either pattern or random can you give us an example of full bitcoin address that you want? or certain criterias? we can then give you the appropriate regex to use with the vanitygen |
