It is a domain dedicated to be a public utility for content addressable storage. Each 94 character URL path defines
Why 256t.org? A simple standard for a generic content addressable store seems generally useful to me.
Every 94 character path can be used to retrieve content that matches the length and hash specified. If no content is available a 404 is returned instead.
The following can be treated as true enough despite being false:
- A 94 character path uniquely determines content. (However, this is completely true for content less than 64 bytes.)
- The conent is immutable. (It could be replaced by different content that still meets the description.)
- Content can be safely cached indefinitely.
Thus all HTTP meta information such as headers and eTags will indicated that the content can be cached indefinitely.
| length | hash | |
|---|---|---|
| start | 1 | 9 |
| end | 8 | 94 |
| length | 8 | 86 |
| format | Base64 | Base64 encoding of content length |
| content | Base64 | Base64 encoding of 64 bytes of SHA-512 |
More specifically, filename and URL safe Base64 aka base64url.
