Method called Encrypt instead of Hash

[aaomidi]

Hi,
On the following line:

gwp/Chapter_2_Go_ChitChat/chitchat/data/data.go

Line 42 in e25181d

func Encrypt(plaintext string) (cryptext string) {

The method is named Encrypt instead of Hash. I understand it wouldn't be possible to solve this now, however for future revisions of this book I think changing the name to be more accurate is important.
