Do you have the ability to have vanitygen continue checking for addresses until multiple have been found of either the same criteria or of different criteria?
For example can you tell it to continue looking until it has found 3x of 1abcdefgh and/or to continue looking until it has found 1abcdefgh, 1ijklmnop and 1qrstuv?
Only for the same pubkey or without providing a pubkey and I cant limit it to a certain number or strike off results. There are basically two flags that help, but are not as flexible as one would hope.
#1 is
-k it ensures vanitygen keeps going after finding a key. It does not stop a certain number though, it has to be cancled manually.
#2 is
-f pattern.txt it allows you to store any amount of prefixes in a file and it will search for all of them at once. If it finds any it will stop (or not with -k). It will keep finding easier (low diff) results though and not strike them off the list.
E.g. this is the file I made for referee
1Referee
1referee
1R3feree
1r3feree
1Ref3ree
1ref3ree
1Refer3e
1refer3e
1Refere3
1refere3
1R3f3ree
1r3f3ree
1R3fer3e
1r3fer3e
1R3fere3
1r3fere3
1R3f3r3e
1r3f3r3e
1R3f3re3
1r3f3re3
There is also
-r which allows to search for regular expressions (e.g. the above would be 1[R,r][e,3]f[e,3]r[e,3]{2}). Thats however not working with the GPU.
