Apple released released Safari Technology Preview 41 (Safari TP41) on Wednesday. This release tests out the Files and Directory Entries API, as well as a new encryption scheme called Elliptic Curve P-521.
Files and Directory Entries API
The Files and Directory Entries API allows browsers to find, create, and edit files in a sandboxed environment. It remains to be seen what Apple does with this, and it’s not yet a full web standard.
Elliptic Curve P-521
Elliptic Curve P-521 Is an approach to encryption designed to offer the the same levels of encryption as other schemes, but with shorter (smaller) encryption keys.
