If I have a vanity address does it decrease my wallets security?

Question

I've seen some people with vanity Monero addresses like 43COINxxxxxx. Does having a vanity address like this increase its susceptibility to getting cracked and view/spend keys getting found?

Answer 1

In terms of cryptography: no, unless the vanity generator is badly implemented, without a proper source of entropy.

Although, if you use an untrusted vanity generator, they could record your private key and send it somewhere. Good old trick.
