I know that PBKDF2 is very useful for generating strong keys. I'm trying to know is there any additional contribution of the given password to produce even stronger keys.
Which key is more secure:
- A password: "123456" (length 6) is entered into PBKDF2 ---> Produced key
- A password: "XK6f+d" (length 6) is entered into PBKDF2 ---> Produced key
- A password: "123456789" (length 9) is entered into PBKDF2 ---> Produced key
- A password: "dYn5p78+/" (length 9) is entered into PBKDF2 ---> Produced key
- A password: "eh4P+S83ko/@bDBq" (length 16) is entered into PBKDF2 ----> Produced key
Does the strong key generation of PBKDF depends on the length of the password? Does longer passwords produce more stronger keys then shorter passwords? Does "XK6f+d" produces more stronger keys then "123456"?
