[xeroc]

use
$ vanitygen -r "1[A-Z]{8,10}"
to get 8 to 10 upper case letters A-Z

use
$ vanitygen -r "1[a-zA-Z]{8,10}"
to get 8 to 10 upper and lower case letters a-zA-Z

and so on

You want to choose 32 characters?

What he wants to say is: You need a next to infinite amount of time to get one.

No. I want any address that is 32 characters long. According to the Bitcoin wiki, Base58 can be as short as 27 characters.

Would the following work?

$ vanitygen -r "1[a-zA-Z0-9]{31}"

How about:

$ vanitygen -r "1TF[a-zA-Z0-9]{29}"

As short as 26 characters actually:

You want to choose 32 characters?

No. I want any address that is 32 characters long. According to the Bitcoin wiki, Base58 can be as short as 27 characters.

Would the following work?

$ vanitygen -r "1[a-zA-Z0-9]{31}"

How about:

$ vanitygen -r "1TF[a-zA-Z0-9]{29}"

v0.22 doesn't seem to support -r.

git checkout https://github.com/samr7/vanitygen.git

interesting .. i dont even see a v0.22 in git tag list

-r is cpu only

[CIYAM]

Why not just use 1TF repeatedly and filter out all non-32 byte addresses?

No correct answer to the original question of the OP up to now...

So, here's the correct answer for vanitygen 0.22 (tested under Linux) (the option "-k" at the end is optional and makes it generating more addresses after one has been found):

Generate a key with address length=34:

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{33}$" -k

Generate a key with address length=33:

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{32}$" -k

Generate a key with address length=32 (Hint: This may take a little while...):

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{31}$" -k

Generate a key with address length=31 (Warning: This may take quite a while...):

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{30}$" -k

Generate a key with address length=30 (Warning: This may take VERY long!):

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{31}$" -k

Generate a key with address length=29 (Warning: This may take VERY VERY long!):

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{28}$" -k

Generate a key with address length=28 (Warning: This may take VERY VERY VERY long!):

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{27}$" -k

Generate a key with address length=27  (Warning: This may take VERY VERY VERY VERY long!):

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{26}$" -k

Explanation:
To get *exactly* a certain amount of characters (32 for example), you need a regular expression that includes the indicators for "start of string" (^) and "end of string" ($).

For example the regular expression

Code:

^1[a-zA-Z0-9]{31}$

means:
After the (invisible) start character (^) there is a "1", followed by exactly 31 occurrences of any character a-z or A-Z or 0-9, followed by the (invisible) end character ($).

In contrast, the regular expression

Code:

^1[a-zA-Z0-9]{31}

(i.e. omitting the trailing "$") means that an arbitrary number of characters may follow after the first 32 characters --> so in this case you will end up with a 34 character address in most cases, instead of the desired address of length 32.

A few examples of addresses of 32 characters length generated with above method:

Code:

Pattern: ^1[a-zA-Z0-9]{31}$
Address: 111ewZDvNuUB1vu7xK7KNWwzU35gNJkW
Privkey: 5HrMK2FSRD7dcRJ7unXYLmC6ZA5zSgJP1fdtXdAQ5Xc4tD1U7fk
Pattern: ^1[a-zA-Z0-9]{31}$
Address: 111vB1s4BdUhvoKhdo6waSCqkB8d9tJ1
Privkey: 5J1BgHaSs8o9fPVPTxbRd2jp7ouSAP8eKi5dpcMi1z59RECZs1U
Pattern: ^1[a-zA-Z0-9]{31}$
Address: 111uSRFo91baBW2A8jRqXNJFdhvCFMJK
Privkey: 5Jgv9enDmwpAVkPcZBzZkntBnpSsHutf8amoMv6mPBSDAdvARYj

PS: To generate an address of length 32 characters *or less*, you would do this:

Code:

$ ./vanitygen -r "^1[a-zA-Z0-9]{0,31}$" -k

It means: After "start of string" (^), put a "1" (one), followed by "n" occurrences of a character or number, where "n" can be anything between 0 and 31. This is followed by "end of string" ($).

[Michael_S]

You want to choose 32 characters?

What he wants to say is: You need a next to infinite amount of time to get one.

I generated 11 addresses of *exactly* 32 characters length each within 10 or 15 minutes, on a more than 7 years old CPU that was already cheap when I bought my PC.

That is not really what I would call "infinite amount of time".

[flatfly]

Why not simplify your regexes as follows:

rather than: 1[a-zA-Z0-9]{31}
try:            .{32}

and so on...
