cryptographic hash is a function which takes a string of bytes and returns a small, fixed-size value. Hash functions guarantee that the same input always results in the same output. When used for security, the most the difference between the legitimate and malicious files based on the hash. The following hash functions are not considered cryptographically secure and should not be used: • All MD-family hashes (such dangers of SHA1 please see https://shattered.io/ Reproduction Steps The following list identifies functions in the Istio project that are using insecure hashing algo- rithms: • istio/istio/mixer/adapter/list/list
