Hash snag: Security shamans shame SHA-1 standard, confirm crucial collisions citing circa $45k chip cost

Unsafe hashing algorithm really is unsafe

SHA-1 stands for Secure Hash Algorithm but version 1, developed in 1995, isn't secure at all. It has been vulnerable in theory since 2004 though it took until 2017 for researchers at CWI Amsterdam and Google to demonstrate a practical if somewhat costly collision attack."
