What is the difference between "the work required to stretch a spring" and "the work done by a spring"?

2. Relevant equations

Fdx = dW

F (from the spring)= -kx

so, F (from me) = kx

3. The attempt at a solution

I have tried and I found out the work required to stretch a spring x1 to x2 is(1/2)k(x2^2 - x1^1)

and "the work dont by a spring" when it's released from x1 to x2 is the same thing but in opposite sign

Am I right?
