Your FAFSA data is protected by encryption. Encryption uses a mathematical
formula to scramble your data into a format that is unreadable by anyone who
might intercept it. If your browser is configured correctly, encryption is
done automatically when you connect to *FAFSA on the Web*. Encryption
strength is measured by the length of its "key," which is expressed
in bits. The larger the key, the greater the strength of the encryption. For
example, we say throughout the introduction screens of the FAFSA that "international"
versions of Internet Explorer use 40-bit keys to encrypt data, while "domestic"
versions of the same browser use 56-bit or 128-bit keys. Consequently, the
domestic versions of Internet Explorer will offer your data stronger protection.
In fact, data encrypted with a 128-bit key is approximately 309,485,009,821,345,068,724,781,056
times stronger than data encrypted with a 40-bit key.We recommend that you
use the domestic version of your preferred browser.
