VPSKeys

VPSKeys supports the Telex, VISCII, VNI, and VIQR input methods, as well as a number of character encodings. One of its unique features is a "hook/tilde dictionary" (), which provides spelling suggestions for distinguishing words with or tones. This feature is helpful for speakers of dialects in which these two tones have merged. ==VPS character encoding==

The "VPS" character encoding for writing Vietnamese replaces several control characters, including several C0 control characters, with letters while including the ASCII graphical characters unmodified, a similar approach to VSCII-1 (TCVN1) and VISCII. ==Trojan incident==

In March 2010, Google and McAfee announced on their security blogs that they believe that hackers compromised the VPS website and replaced the program with a trojan. The trojan, which McAfee has code-named W32/VulcanBot, creates a botnet that could be used to launch distributed denial of service attacks on websites critical of the Vietnamese government's plan to mine bauxite in the country's Central Highlands. McAfee suspects that the authors of the trojan have ties to the Vietnamese government. The Vietnamese Ministry of Foreign Affairs issued a statement calling Google's and McAfee's comments "groundless". VPS discovered a breach on their website on January 22, 2010, and restored the non-infected software then, but did not publicize it widely because they did not realize the serious nature of the matter. == References ==
