How does Hyperledger fabric EVM generate the address from the public key?

In Ethereum, the wallet address is the last 20 bytes of the keccak256 hash of the public key of the wallet.

I am working with Hyperledger Fabric EVM, and I would like to know which is the mechanism that is used to generate the address from the public key.

I applied keccak256, sha256, and sha-3 256 to my public key, but I didn't get the correct address...

It is my private key in pem format:

-----BEGIN PRIVATE KEY-----
MIGHAgEAMBMGByqGSM49AgEGCCqGSM49AwEHBG0wawIBAQQgjUp+AWrFlIVp13Dl
rpm/Uu2M++ZhOC4AbmjWdsofP7ihRANCAARWnvMdt+149KEt9yPKoLHG98lL5wPe
cGVMBMxsJhz3JLBSQlBCfLMz8fe5vIng4N7TGYt66P2HNeG/fLjwt7jI
-----END PRIVATE KEY-----

It is my public key in pem format:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEVp7zHbftePShLfcjyqCxxvfJS+cD
3nBlTATMbCYc9ySwUkJQQnyzM/H3ubyJ4ODe0xmLeuj9hzXhv3y48Le4yA==
-----END PUBLIC KEY-----

It is my public key in hex format:

Public_key = 0x04569ef31db7ed78f4a12df723caa0b1c6f7c94be703de70654c04cc6c261cf724b0524250427cb333f1f7b9bc89e0e0ded3198b7ae8fd8735e1bf7cb8f0b7b8c8

And it is my address:

13065B11B498911F2A19815035D0AC24457D1BB6

I am using secp256r1

Solution

  • The address is the last 20 bytes of the sha3-256 of 3059301306072a8648ce3d020106082a8648ce3d030107034200 + public_key_hex

    In my example, take the last 160 bits (20 bytes) of "result" :

    var Public_key = 0x04569ef31db7ed78f4a12df723caa0b1c6f7c94be703de70654c04cc6c261cf724b0524250427cb333f1f7b9bc89e0e0ded3198b7ae8fd8735e1bf7cb8f0b7b8c8
var result = SHA3_256(0x3059301306072a8648ce3d020106082a8648ce3d030107034200 + Public_key)
var address = last_20bytes(result)

console.log("address = ",address);

//address = 13065B11B498911F2A19815035D0AC24457D1BB6
