Enter hardness: a value between 1000 and 3000.

Your email:

Your secret phrase:

Remeber and/or backup all above! There is no restore option!

Your private key will be the result of hardness times recursive calls of keccak_256 hash function over message. Where 1st message is concatenaited email and secret phrase and then repeated, again, hardness times:
Step(1) = keccak_256[hardness * (email + phrase)].
Step(hardness) = keccak_256[hardness * Step(hardness-1)],
where "+", "*" are string operations: concatenation and multiplication. Do step(n) passed to Step(n+1) as a 64 hex chars string (without leading '0x') repeated and concatenaited _hardness_ times.
This formula and 3 parameter values your entered above will allow you to regenerate your private key at any time.

This can take a minute.
