This question is similar to this, but that one only references MD5 collision demos.
Are there any actual SHA1 collision pairs of arbitrary messages known so far ?
I'd like to use these to test how various software products (my own one and some third party) deal with it.
Doing some Google searches only turned up the oh-so prominent MD5 / SHA0 collisions and some hints on an approach to creating SHA1 collisions but I could not get my hands on any examples.
