and then generate a collision. Note that the number of files could be arbitrary and there are more clever scenarios. The program serves only as a toy example how to get arround the necessity of creating the second preimage. Vlastimil Klima

o controll them also. New differential schemes (paths) could be proposed, new ways of controlling the interior variables of MD5 could be discovered. It could lead to the second preimage attacks and maybe further. Vlastimil Klima - PŮVODNÍ ZPRÁVA - Od: "Victor Duchovni" <

I agree with Steven´s "I'd rather avoid HMAC-MD5, just as a matter of future-proofing". And more. In am nearly sure that a preimage attack (MD5) will be found in the next two or three years. Vlastimil Klima http:/cryptography.hyperlink.cz - PŮVODNÍ ZPRÁVA - Od: &quo
