I have to assume he means SHA-256, and not SHA-512.

git apparently supports using SHA-256 instead of SHA-1 hashes,
but support does not seem to be very mainstream. I am not even
sure GitHub supports it (https://github.com/orgs/community/discussions/12490
seems to indicate not yet).

So either this is vcpkg trying to be vey aggressive in
requiring git features, or there is some clarification neeed.

Can you elaborate what the problem is ?
I would have thought https://git.ffmpeg.org/rtmpdump.git
is secure

thx

[FFmpeg-devel] Request for Official GitHub Mirror of rtmpdump for Enhanced Security

2024-04-23 Thread Javier Matos Denizac via ffmpeg-devel
Dear FFmpeg team,


My name is Javier Matos, and I am part of the vcpkg team at Microsoft. vcpkg is 
an open-source package manager designed to help developers manage C++ libraries 
across platforms in a consistent manner.

I am reaching out to inquire if FFmpeg could host an official GitHub mirror for 
the `rtmpdump` repository on `github.com/FFmpeg`.

Currently, vcpkg uses a mirrored version from `github.com/mirror/rtmpdump`, 
which is not maintained by the original authors, posing a significant supply 
chain risk due to potential unauthorized modifications.

Alternatively, while we could switch to using the repository at 
`git://git.ffmpeg.org/rtmpdump.git`, this source lacks support for SHA512 
checksums, complicating asset caching and security verification crucial for 
ensuring the integrity of the code during downloads.

An official GitHub mirror hosted by FFmpeg would address these issues by 
providing a secure, verifiable source that we can integrate with vcpkg. Thank 
you for considering this request. I look forward to your feedback.

Best regards,

Javier Matos
