Mega.co.nz uses that to hide the decryption key for almost decade. You share links but Mega never knows your key because fragment hash is never sent to server or in referrer. Encrypted files are stored on Mega servers but the decryption occurs in JS on the client side, files are decrypted into temporary JS Blob objects in browser then you save them aka "download" locally... a lot of clever tech there. https://help.mega.io/security/data-protection/end-to-end-encryption https://help.mega.io/security/data-protection/end-to-end-enc...
