Are web3.personal.sign
and web3.eth.sign
difference in value of generate signature ? Or both of them generate an equal output ?
I could test web3.eth.sign
using testRPC
, however web3.personal.sign
with testRPC
gives error and I could not compare the output of both method with the same input.

I think I had similar problem. I couldn't get correct address from ecrecover after message was signed with personal.sign, but it works fine after it was sign with eth.sign. Then I found this on web3 docs: https://web3js.readthedocs.io/en/1.0/web3-eth-personal.html#sign
After I added "\x19Ethereum Signed Message:\n" and message length to signed message, from which I want to recover address, it finally return correct address.
