For now, 2 official places can be found to download the Daedalus Wallets:
But no SHA256 (or MD5, etc.) for the wallets can be found in either the address above. Sometimes people want to check the authenticity of the file downloaded, so I think it’s better if they are provided.
This may also help those who download the wallets from other server, for they just have poor internet connection to these sites.
