Clipperz is a free and open-source software[2] Cloud-based password manager and content repository for storing sensitive information.[3]

Clients do not register or provide any other information about themselves when creating an account.[4]

Interface

Read/write access to account data is available through any wired or mobile web browser platform with JavaScript[5] support[6] and Internet access.[7]

A local read-only copy can be created for situations where the Internet is unavailable or if the Clipperz server itself is down.[8] A five-digit PIN can be created as a passphrase alternative for use on a trusted local device.[9]

Overview

To open an account a user enters a "name" and a passphrase of any length. One-time password keys can be generated for use in insecure settings. Structured data is entered in paired "label/value" fields. Each card can also hold file attachments. Accounts are limited to 100 MB.[9]

Export

Structured data is exportable in HTML+JSON or XML formats. Attachments can be individually exported to the native file system.[8]

Import

Structured data can be imported in pre-formatted CSV or JSON[9] using drag and drop or the file system. Attachments can be individually imported using drag and drop or through the file system.

Clipboard support

Clicking any structured data field copies its content to the native operating system's Clipboard (computing).[8]

Technical Support

Support is available through a Google groups forum,

Internet Relay Chat (IRC) server.[11]

Technology

The company describes Clipperz as a "host-proof web app."[12] Such technology is more commonly described as a zero-knowledge password proof (ZKPP) single-page web[12] application.[13] The product's taglines "Do not trust us!" and "Keep it to yourself" allude to the fact that the client authenticates its identity using a passphrase that is locally encrypted before being sent to the Clipperz server.[14]

128-bit security level in CTR mode with 256-bit key size cryptography[15] is provided through Clipperz's JavaScript Crypto Library.[16] A Clipperz HTTP cookie maintains the current session through a Secure Remote Password protocol (SRP).[17] An open source version of Clipperz is available for testing and educational purposes only.[18]

https://clipperz.is is registered in Iceland. The primary Clipperz server is located in Amsterdam, with a backup in Reykjavik.[19]

History

The eponymous product was released in April, 2006 as a proof of concept for "zero-knowledge web applications."[20] Version 2 was released in July, 2015.[12]

User base

As of approximately 2016, the service claimed 100,000 registered accounts with approximately 10,000 daily users.[12]

Ownership

Clipperz Srl is an Italian resident limited liability company formed in 2005 by Giulio Cesare Solaroli[21][22] and Marco Barulli.[23]
