Subject: SHA-1 chosen-prefix colission attack
Message-ID: <20200107173111.GB923852@alpha>

Researchers published new advances in creating collisions in SHA-1
hashes: https://sha-mbles.github.io/

> As a side result, this shows that it now costs less than 100k USD to
> break cryptography with a security level of 64 bits (i.e. to compute
> 264 operations of symmetric cryptography).
