ZeroBin 0.15 Alpha
|
||||||
|
=== THIS IS ALPHA SOFTWARE - USE AT YOUR OWN RISKS ====
|
||||||
|
|
||||||
|
ZeroBin is a minimalist, opensource online pastebin where the server
|
||||||
|
has zero knowledge of pasted data. Data is encrypted/decrypted in the
|
||||||
|
browser using 256 bits AES.
|
||||||
|
|
||||||

The idea is to creates subdirectories in order to limit the number of files per directory.

(A high number of files in a single directory can slow things down.)

eg. "f468483c313401e8" will be stored in "data/f4/68/f468483c313401e8"

High-trafic websites may want to deepen the directory structure (like Squid does).
