Thank you very much for the reply,
As I thought, md5 is obsolete and the encryption has changed.
So, is there any way of knowing what type of encryption the function uses: passwordhash ($password, PASSWORDBCRYPT) to do the same in angular and in this way to be able to compare if the password of the app is the same as that of bbdd?
Or I have to create a new controller in prestashop to pass the password and check it with passwordverify ($providedpassword, $userpasswordin_db)
