Description

We support 3 wallet sub-types and print a warning that the "hashes" could reveal the private key for all 3, whereas we probably only need to do that for 1 out of 3 (presale), see https://github.com/openwall/john/issues/3130#issuecomment-756786655

    sys.stderr.write("WARNING: Upon successful password recovery, this hash format may expose your PRIVATE KEY. Do not share extracted hashes with any untrusted parties!\n")

Research direction

Start in ethereum2john.py, locating the warning and the code that distinguishes the three wallet sub-types. Confirm which subtype is the presale format, then verify that the private-key warning is emitted only for it and that the other two formats retain their existing processing.
