Turns out that Securecoin uses nonstandard constants* to generate addresses.
So, without much further ado: https://github.com/llamasoft/securecoin-vanitygen
I will not be distributing compiled binaries, but if you know how to run "make", you can make them yourself.
To generate a securecoin address, just use the -S flag:
$ ./vanitygen -S secure
Difficulty: 264104224
Pattern: secure
Address: secure1qeuUrEmr2LVucyDBymM7kaiHTE2
Privkey: === REDACTED ===
Enjoy!
*: When it comes to cryptocoin addresses, you have two parts that determine some key info about the key. There's the address type (PUBKEY_ADDRESS) and the address version.
Normally, the address version is 128 + address_type, but in this case it was hard coded to 128.
