128 Bit Browser Encryption
Web Browser Requirements
My Account in TreasuryDirect requires a browser that supports 128-bit encryption. Opening an account, as well as buying securities and managing your account, involves the transmission of sensitive data, such as your Taxpayer Identification Number (e.g., Social Security Number) and your bank information. 128-bit encryption provides high-level security for these transmissions and is the industry standard for electronic financial transactions.
If your browser does not support 128-bit encryption, please visit the website that provides upgrades to your browser software. If you are using a Microsoft or Firefox browser, you should upgrade to Windows Internet Explorer 7 or later or Firefox 2 or later:
Establishing a Secure Connection or SSL Connection
Secure Sockets Layer (SSL) is a common protocol for sending confidential information securely over the Internet. SSL works by using a private, mathematical key to encrypt (or scramble) data that's transferred between your Web browser and the website you're visiting.
