This is an implementation of Marc Stevens' Counter Cryptanalysis in Go
It implements the hash.Hash interface, as well as a new detectcoll.Hash interface, which adds the method:
hashBytes, ok := h.DetectSum(appendTo)You can also import github.com/therealmik/detectcoll/sha1 and github.com/therealmik/detectcoll/md5
to register the hashes with the crypto subsystem, and they'll log with the golang log package if a collision attempt
is detected.
There is a C version written by Marc Stevens and plenty of great hash breaking resources at his website.
To install:
go get -u github.com/therealmik/detectcoll
