What is Secure Sockets Layer (SSL)?

Secure Sockets Layer (SSL) is a secure way to transmit personal information from your computer to Citizenship and Immigration Canada CIC. SSL uses encryption, which helps make information sent through the Internet more secure. Internet services like online banking or shopping—for which security of information is important—often use 128-bit SSL encryption. When you access the personal information area of Client Application Status (CAS), CIC will make sure your browser supports SSL.
