Why does decryption process take so long?
A. Your computer is poorly configured and you need a high-frequency and multi-core CPU to ensure the speed of operation.
B. You have too many keywords. In version 1.0，all softwares calculations depend on your own computer, and the speed of stand-alone computing is limited. If you have no idea at all of your wallet password or it was more than a handful of characters long，then it is unlikely that we can help you. No-one in the world can crack the encryption used in the Bitcoin wallet if the password is more than 20 fairly random characters. Each additional one-digit password or one more character which participates in the combination will lead to an exponential increase in the total number of combinations. Therefore, in the case of more password digits and more combination characters, a single computer maybe not quickly test all the password combinations, so it takes a long time to wait.
