Profanity is the fastest vanity generator for ethereum addresses and contract addresses.
"profanity3 is a fork of "profanity2" from 1inch Network info@1inch.io, which fixes the security problems of the original "profanity" from Johan Gustafsson profanity@johgu.se.
"profanity3" from Rodrigo Madera madera@acm.org, is the same as "profanity2" with just one special feature: it can reverse engineer "profanity1" keys.
"profanity3WINx64" is a fork of "profanity3" with some adjustments to compile for windows.
A previous version of this project (hereby called "profanity1" for context) has a known critical issue due to a bad source of randomness. The issue enables attackers to recover the private key given a public key: https://blog.1inch.io/a-vulnerability-disclosed-in-profanity-an-ethereum-vanity-address-tool/
The good guys at 1inch created a follow-up project called "profanity2" which was forked from the original "profanity1" project and modified to guarantee safety by design. They claim that "this means that the source code of this project does not require any audits, but still guarantee safe usage." Kind of a bold statement (if you ask me) although it's pretty much true.
The "profanity2" project is not generating keys anymore (as opposed to "profanity1"). Instead, it adjusts a user-provided public key until a desired vanity address is discovered. Users provide a seed public key in the form of a 128-symbol hex string with the -z parameter flag. The resulting private key should then be added to the seed private key to achieve a final private key with the desired vanity address (remember: private keys are just 256-bit numbers). Running "profanity2" can even be outsourced to someone completely unreliable - it is still safe by design.
Generate private key and public key via openssl in MSYS2-terminal (remove prefix "04" from public key):
$ openssl ecparam -genkey -name secp256k1 -text -noout -outform DER | xxd -p -c 1000 | sed 's/41534e31204f49443a20736563703235366b310a30740201010420/Private Key: /' | sed 's/a00706052b8104000aa144034200/\'$'\nPublic Key: /'PRIVATE_KEY_A = private key from "Generate private key"
PRIVATE_KEY_B = private key from "profanity"-search result
Use private keys as 64-symbol hexadecimal string WITHOUT 0x prefix:
(echo 'ibase=16;obase=10' && (echo '(PRIVATE_KEY_A + PRIVATE_KEY_B) % FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F' | tr '[:lower:]' '[:upper:]')) | bcUse private keys as 64-symbol hexadecimal string WITH 0x prefix:
$ python3
>>> hex((PRIVATE_KEY_A + PRIVATE_KEY_B) % 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F)>>> (echo 'ibase=16;obase=10' && (echo '(0bc657b0af28b743c7f0d49c4de78efd47a5c8923dabfdef051fff5cdc7c30e7 + 0x0000f8ba428990fca1e618a252ac3614f5de19b20ff00c2ded57bfb6933830aa) % FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEFFFFFC2F' | tr '[:lower:]' '[:upper:]')) | bc
>>> BC7506AF1B2484069D6ED3EA093C5123D83E2444D9C0A1CF277BF226FB49AD0
>>> 0BC7506AF1B2484069D6ED3EA093C5123D83E2444D9C0A1CF277BF226FB49AD0 (Pad with 1 zero as length only 63)Note that if less than 64-symbol is generated, simply add leading zeroes to the private key. This occurs due to the summation of PRIVATE_KEY_A & PRIVATE_KEY_B with leading 0s not being displayed in final hex generated. Example above has 1 overlapping leading 0 thus we add an additional zero.
usage: ./profanity3 [OPTIONS]
Mandatory args:

This project "profanity3" was forked from the "profanity2" project and
modified to allow you to assess the quality of your "profanity1" keys.
No guarantees whatsoever are given, so use this at your own risk and
don't bother me about it. Also, don't be evil. Use this to assess
your own addresses and keep them safe. But better yet, if you have
any wallets generated with profanity1, just throw them away.
