Rehashing CodeCentral hash values

with 2 comments

Shortly after my blog post about finally displaying MD5 hash values for CodeCentral downloads, Jorge Almeida asked about SHA1 hash values instead because of the known collision problems with MD5. So, we now are displaying not only MD5 hash values but also SHA1 hash values for each CodeCentral download that has an attachment, as illustrated (once again) in the MD5/SHA1 Hash Generator upload.

When you go to that item, you will now see in the details section:

SHA1 Hash: 4A6F1A4808A1E295D309F5F15E20336FAB08D6BC
MD5 Hash: 7ACEF4E7E2A223B59F92070039FD1947

Hopefully, we won’t have to rehash the hash values in CodeCentral again.

  1. Hi,

    I’ve developped a tool called Hash Generator which handles CRC32, MD5 and SHA1 hashing. It should be useful here.

    It’s available here:
