Dev writes Ethereum code for insecure SHA-1 crypto hash function

Re: SHA1 is totally dead.

I'm afraid you are mistaken. Git still only supports SHA1, as do DNSSEC NSEC3 records.

Re: There's a difference ...

Public key cryptosystems don't sign data directly - they sign cryptographic hashes. A compromise in SHA1 can potentially make the same signature valid for two different plaintexts if the signature was generated using SHA1.
