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 to use SHA-1 instead of MD5, as there appears to be some concern with MD5 over it's compression function. HTH JH
It helps :) I have been looking into Blowfish with cbc mode :) If I use SHA-1 it's still no way to dehash it during decryption of the file, so I fail to see the use of Hashing in fileencryption. Could someone enlighten me? / Jim
