Question

At the moment I have a database field which stores passwords like this:

TeacherPassword

j.lu01
pesci02
cricket01

But I want to change the password field so that each row contains hashes for each password. But how can this be done because I tried an update like below but it did not work:

UPDATE Teacher
SET SHA2 TeacherPassword

I am using sql in phpmyadmin

Answer 1

MySQL has a SHA1() function

UPDATE Teacher
SET SHA1(TeacherPassword)

Or even Password()

UPDATE Teacher
SET Password(TeacherPassword)

Encryption functions in MySQL
