Vanity address generation for Segwit? Vanity address generation is currently strightforward for "old" Bitcoin addresses (starting with 1) with multiple software options available (oclvanitygen e.t.c).

Is there any options to generate SegWit Vanity address (starting with 3)? Or it is already possible to configure existing software for Segwit addresses?
Segwit, until BIP 173 is widely used, uses P2SH addresses. These addresses currently begin with a 3 and you can find them on the blockchain right now.

AFAIK, there is no software which will produce vanity P2SH addresses since there isn't just one thing that it can try over and over; the address is based on a script which could have anything, unlike the 1... Bitcoin addresses which are only based on one public key.

Since there are no P2SH vanity address generators, there is not one for Segwit. However it would not be hard to make such a software.
