Your example describes a preimage attack on SHA-1, not a collision attack. Even with a working collision attack you are probably still far away from taking "some.other.input" and creating a sha1("some.other.input") = sha1("johndoe:creditcard"). For instance MD5 collisions are really easy to create but for preimage attacks on MD5 there is still no better approach than just doing brute force. |
