Why does Arch uses md5 and sha1 algorithms as checksum?

Re: Why does Arch uses md5 and sha1 algorithms as checksum?
Because you should use the PGP signature to check validity, the checksums are only used to check integrity.

Can you please elaborate?

If a malicious actor did manage to replace the iso file with a file that had the same md5 and/or sha1 fingerprint, the file would not pass the PGP signature check.

Wait what's it with PGP? Isn't this command check checksums?

No, it checks the PGP signature that WorMzy mentioned.

Or the https://wiki.archlinux.org/title/Instal … _signature …
md5/sha1 mismatches tell you that the download was crippled and on some inferior OS which usually don't have any pgp/gpg installation but the md5 in the files context menu, it's still much MUCH better than nothing.
