| Oct 31, 2012 at 5:19 | comment | added | user236501 | I found a SHA1 extension attack, if said the hash format is (a||b||constant value), is it possible that I create another hash code (c||b||constant value) without knowing the constant value. | |
| Oct 31, 2012 at 5:00 | comment | added | Thomas | @user236501 No, but if the constant value is short enough we'll reach it eventually, by going "try every 1-character combination... OK we've tried them all and nothing worked, move on to every 2-character combination" and so on. | |
