I created a wallet using geth (1.6.0-stable).
I can unlock it using geth: The command
personal.unlockAccount(address) asks for the password and returns true.
But when I use https://www.myetherwallet.com/#view-wallet-info I get the error message "Invalid password. Error: Key derivation failed - possibly wrong passphrase"
I upload the only keystore from ~/.ethereum/keystore and copy the exact same password...
It seems the keystore file (UTC/JSON) formats are different between geth and myEtherWallet...
Please do you confirm? How should I import the wallet?
