Help WIth Keychain Access

Hi Community,
So I finally got a new computer after about 5 years, and as great as the new one is, I sorely missing all of my Keychain Access passwords. Seeing as it is a pain to have to enter all of these passwords I’ve grown used to neglecting (and there are also a few I’ve found I can no longer remember), I went back to the old computer to get the passwords. However, there are a LOT of passwords, and although I’ve one by one gotten the three or four I desperately need for the time being, I really don’t want to have to go through one at a time for EVERY password. Thus, I’ve turned to Applescript. Using the password of the account in the script, can anyone help me make a script that would make an array of all the passwords in my Keychain? Thank you so much!
