verification hashes sums

Post by reactosuser7 »

Could ReactOS files: 'BootCD', 'LiveCD' and files from Trunk Daily Builds have shasums (sha256sum and sha512sum) to verify its integrity?

Or at least md5sums?

GNU/Linux uses verification hashes sums.

SF download page has SHA1 and MD5 sums for BootCD and LiveCD files.

It's not the same thing, but most of the builds get served from HTTPS. Just check the chain of trust.

I added HTTPS and SHA1 support for RAPPS packages (many of which are downloaded from their original locations using plain HTTP), and some other dev added HTTPS certificate pinning for the RAPPS database update.

Overall, I think we are mostly covered in that front.

There are two reasons to use checksums:
1) check if the archive was downloaded properly without errors
2) check whether the storage wasn't tampered with

HTTPS covers the issue 2). The ISOs from build server are compressed into an archive, so there should be a checksum as part of the file format, but IIRC only CRC32 is used, that may not be enough to cover issue 1).
