SHA-1 is a Shambles
We have computed the very first chosen-prefix collision for SHA-1. In a nutshell, this means a complete and practical break of the SHA-1 hash function, with dangerous practical implications if you are still using this hash function. To put it in another way: all attacks that are practical on MD5 are now also practical on SHA-1. Check our paper here for more details. Slides from RWC are also availa
SHAAAAAAAAAAAAA | Check your site for weak SHA-1 certificates.
From late 2014 through the full retirement of SHA-1 at the end of 2016, this site provided a web-based tool to check if a web service's certificate was using the dangerously outdated SHA-1 signature algorithm. Since SHA-1 is largely gone from the ecosystem, this tool has been disabled, but its code remains open source. This also includes a command line tool, which could easily be modified to suppo
