1 General

2 Cryptanalysis

2.1 Collision Attacks

Here I would list all papers that deal with SHA-1. We should also give the abstract and the bibtex entry for the corresponding paper. Additionall we should give our opinion about the attack described in the paper.


2.2 Second Preimage Attacks

There exists a generic attack (works for all iterated hash functions). See ....

2.3 Preimage Attacks

We are not aware of any article describing preimage attacks on SHA-1.


3 eHASH Recommendation

Something like: SHA-1 is considered to be broken. Please do not incorporate SHA-1 in new application any longer. Try to migrate to another hash function.
