Yes. But what are you trying to do? Usually those requests mean someone's trying to brute-force existing addresses, which won't work.
I don't want to search for specific patterns like 1Love, but create many addresses and pick out the best patterns that I might like. Bitcoin would also be enough for me, it is important to me that it creates 12 or 24 seeds and works with Cuda.
You can create tons of addresses via VanitySearch or VanityGen, so many in some seconds that I think you'll get exhausted to check each of them. Btw it won't randomly generate beautiful address though.
Does VanitySearch also support 12 or 24 seeds? If necessary, it also works without would only be nice because of the compatibility with other wallets. Or is there possibly a possibility to convert a private key afterwards to a seed? I think I read something that you convert it into bites and then the bites into words.
I think you'll find this thread and this particular post very interesting:
