Hi Sir any chance that you could explain how to use AES to build a secure HASH?

[@ChiragBhalodia]

Hash function is not reversible and AES is reversible. AES is more secure in compare to hash function. But whenever you want to add confidentiality in hash function, you can apply any symmetric cipher algorithm, that algorithm output must be same as hash function in bits.

AES is used for protecting confidentiality where secure HASH is for integrity, authentication so how would u combine both ??
