It's absolutely important in the security of hashes.
- noway421 10y agoAvalanche effect is a sign of a good hashing algorithms, but not necessarily all of them. It is very vital in case of SRI indeed, as because SRI also intended to shield from potential MITM somewhere in CDN stack. But SRI is useful in other areas too. For example for really bare version handling and for handling (somewhat) gracefully corrupted cdn responses (including errors, empty responses etc). For that, avalanche effect is not all that necessary and CRC32 could do an ok job too.
- bartl 10y agoIt's very important in the storage of hashed passwords, but not in checking the integrity of files, which is the use case here.
