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[edit]
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[edit]
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[edit]
Structured data is exportable in HTML+JSON or XML formats. Attachments can be individually exported to the native file system.[8]
Import[edit]
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[edit]
Clicking any structured data field copies its content to the native operating system's Clipboard (computing).[8]
Technical Support[edit]
Support is available through a Google groups forum,[10] Twitter and Skype. Anonymous support is available via an Internet Relay Chat (IRC) server.[11]
Technology[edit]
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[edit]
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[edit]
As of approximately 2016, the service claimed 100,000 registered accounts with approximately 10,000 daily users.[12]
Ownership[edit]
Clipperz Srl is an Italian resident limited liability company formed in 2005 by Giulio Cesare Solaroli[21][22] and Marco Barulli.[23]
