File Transfer Comparisons and Use Cases

Side-by-side comparisons that start from architecture: where the bytes go, who holds keys, and what each design costs.

About this topic

File-transfer tools differ less in features than in architecture: whether the file is stored on a server, whether both people must be online, who holds the encryption keys, and what the network must allow. Starting from those questions makes comparisons more useful than feature checklists, which change every few months.

The comparisons here lead with that architecture and state where each option is the better choice, including cases where SRIFT is not.
