On platforms such as Linux that use multiple incompatible GUI toolkits, clipboard managers are often used to transfer data between applications using different such frameworks.
They are applications that enable the user to manipulate the clipboard.

Joe Siegrist notes that this is an " OS-level issue that impacts everything running on Android".
DEVELOPER OF 1CLIPBOARD ANDROID
In early 2013 researchers exposed risks stemming from Android-based password managers and documented how passwords in 21 of the most popular of these apps could be accessed by any other app on an Android device including those with extremely low-level privileges. There have been exploits where web pages grab clipboard data. Dylan Ayrey who developed the attack set up a website that demonstrates how this exploit can be used to trick a user into running commands they didn't want to run. While some security-holes were patched, JavaScript can still be used to modify clipboard content via an attack dubbed 'pastejacking'. Computer security Ĭlipboard hijacking is an exploit in which a person's clipboard's content is replaced by malicious data, such as a link to a malicious web site. Various type identifiers for data transfer are supported by modern operating systems, which may automatically provide acceptable mappings between type systems, such as between MIME and Uniform Type Identifier. The operating system and GUI toolkit may provide some common conversions, for example converting from rich text to plain text and vice versa. The pasteboard allows for transfer of common items such as URLs, colors, images, strings, attributed strings ( Rich text), and sounds. The sending and receiving application negotiate the formats which can be transferred in between them, oftentimes with the active GUI widget responsible for providing acceptable type transformations.
DEVELOPER OF 1CLIPBOARD MAC OS X
In some circumstances, the transfer of certain common data formats may be achieved opaquely through the use of an abstract factory for example, Mac OS X uses a class called NSImage to provide access to image data stored on the clipboard, though the actual format of the image data backing the object is hidden. Data formats Īpplications communicate through the clipboard by providing either serialized representations of an object, or a promise (for larger objects). Larry Tesler renamed this in 1973 as cut, copy, and paste and coined the term "clipboard" for this buffer, since these techniques need a clipboard for temporary saving the copied or cut data. Since one could delete a text in one place and restore it in another, the term "delete" wasn't what one would expect in this case. History Ĭlipboards as buffers for small text snippets were first used by Pentti Kanerva when he used it to store deleted texts in order to restore them. Windows, Linux and macOS support a single clipboard transaction.
Specific clipboard semantics vary among operating systems, can also vary between versions of the same system, and can sometimes be changed by programs and by user preferences. A clipboard manager may give the user additional control over the clipboard. Application programs may extend the clipboard functions that the operating system provides. When an element is copied or cut, the clipboard must store enough information to enable a sensible result no matter where the element is pasted. It is left to the program to define methods for the user to command these operations, which may include keybindings and menu selections. The clipboard provides an application programming interface by which programs can specify cut, copy and paste operations. The clipboard is usually temporary and unnamed, and its contents reside in the computer's RAM. The clipboard is a buffer that some operating systems provide for short-term storage and transfer within and between application programs. For the physical equivalent, see Clipboard.
