 comment Will length-extension work if secret is not prefixed but appended to the data?
No it isn't. But compared to, e.g., HMAC, it suffers from other flaws. See: Why is h(m||k) insecure?

The output of a PBKDF2 implementation may be hexadecimal, but you can convert that output to whatever you want. Although, there are AES implementations that accept hexadecimal keys.
