New research into attacks against the SHA-1 cryptographic algorithm lessen the cost and time to arrive at a practical collision. When Bruce Schneier made his oft-cited and mathematically sound ...

If you thought MD5 was banished from HTTPS encryption, you’d be wrong. It turns out the fatally weak cryptographic hash function, along with its only slightly stronger SHA1 cousin, are still widely ...

The old and insecure MD5 hashing function hasn’t been used to sign SSL/TLS server certificates in many years, but continues to be used in other parts of encrypted communications protocols, including ...

A design flaw in the decades-old RADIUS authentication protocol allows attackers to take over network devices from a man-in-the-middle position by exploiting MD5 hash collisions. The “secure enough” ...

In general, unless you're specifically tailoring input to produce collisions, collision risk of a (formerly, in case of md5 and by now also sha1) cryptographically secure hash function is not ...
