(July 2009) () () A software protection dongle (commonly known as a dongle or key) is an electronic and content protection device which, when attached to a computer or other electronic appliance, unlocks software functionality or decodes.

The hardware key is programmed with a or other cryptographic protection mechanism; it attaches via electrical connector to an of the computer or appliance. When used as a software protection device, dongles mostly appear as two-interface security tokens with transient data flow that does not interfere with other dongle functions and a pull communication that reads security data from the dongle. Without the dongle, the software may run only in a restricted mode, or not at all. When used as a device attached to a computer or TV or gaming console, dongles can enable functions that would not be present without it. For example, a dongle attached to a TV may receive an encoded video stream, decode it in the dongle, and then present this audio and video information to the TV. Real Lives 2007 Game.

Dongle – needed to expand internal ROM capacity in early QLs In late 1970s/early 1980s, Wordcraft became the earliest to use a software protection dongle. Uwsc Pro 4.2 Keygen. [ ] The dongle was passive using a 74LS165 8-bit shift register connected to one of the two ports on the microcomputer. The tape cassette port supplied both power and bi-directional data I/O. The requirements for security were identified by the author of the Wordcraft word processor, Pete Dowson, and his colleague Mike Lake. Through the network of PET users in the UK they made contact with Graham Heggie in Coventry and Graham's knowledge of electronics meant that they quickly arrived at the idea of a 74LS165 shift register connected to the tape cassette port which provided 5V power and lines to shift the bits into the software.
