I was mixing up with the attack against twofish with reduced rounds (I think
this is true of blowfish with reduced rounds as well )

calculate a hash of the pass the user enters and store that. When the user
enters a pass again to get the data, then hash this pass and see if it
matches the stored hash. If it does , then send the user the data.
create a table that stores username, and hashed passwords for
authentication.

And why not use AES, which is an industry standard and having
being proven as the best encryption algorithm in recent times?

why use AES? Blowfish can have a 448 bit key size! Also, why use ebc mode
with all the problems which come with it?

File hashing is used to take a hash of the clear text. In this way, you can
append the hash to the encrypted text. When decrypting, you remove this
hash, decrypt the rest of the file, hash this decrypted file and see if the
two hashes match up. If they don't then an incorrect key was used with the
Hi,
I believe that twofish has been successfully broken, so use blowfish
instead. Typically, for encrypting files you will use an algorithm like
blowfish in cbc mode (as opposed to ebc mode) but I don't know if Mcrypt
supports this. Also, when creating the hash of the file, it is probably best

Hi,
Also try www.uklinux.net
They have php and perl cgi (with a mysql or postgres backend)
