Wird in der neuen Version eine bessere Verschlüsselung geben? MD5 ist veraltet und auch extrem unsicher. SHA1 Salted (Hashed) wäre da viel viel sicherer.
Source for this statement?
Now, if someone some how got a hold of your password's MD5 hash, they don't have to decrypt it in order to be able login under your account. Same thing would be if SHA1/512 or any other one-way hashing algorithm used to encrypt the passwords. Yeah, sure, they won't be able crack it open to find out what is your password, but it won't matter in 4images case...
So, changing the algorithm won't help you protect your account in 4images.
There is a way add extra security to the account, i.e. have two passwords: one to use for login, second for changing account information such as password or email, or at least ask for the password when changing such information...
