Hi,

Many thanks for listing me on your developer map.

On sagemath.org I go to Download source [1] then I choose mirror [2]

On the mirror I see:

sage-10.5.tar.gz    torrent    1535.20 MB    2024-12-04 00:28
MD5: 83dab794f87e989a30e248f3b39c40db

There are several potential issues with this:

1. If the mirror is compromised or MITM'ed, it could provide whatever checksum.
There is unencrypted "http://"; mirror University of Washington,
Seattle, WA, USA [3]
Is this a real concern?
2. The MD5 hash function is deprecated since years and considered broken.

One possible approach is to sign with gpg the tarballs or only the hashes.
