You can generate yourself a vanity .onion address using https://github.com/AlexanderYastrebov/onion-vanity-address tool. It can also generate vanity client authorization keypair.

Be careful with vanity address generators. A cryptocurrency market maker once lost around $160,000,000 in a vanity Ethereum address because the generator they used was only seeded with 32 bits of entropy.

This tool uses proper crypto/rand initialisation of the starting key https://github.com/AlexanderYastrebov/onion-vanity-address/b...

Check out my other vanity generators (they all use crypto/rand):
