How Encryption Works

The privacy of communications between you (your browser) and our servers is ensured via encryption. Encryption scrambles messages exchanged between your browser and our online banking server.
  • When visiting online banking's sign-on page, your browser establishes a secure session with our server.
  • The secure session is established using a protocol called Transport Layer Security(TLS) Encryption. This protocol requires the exchange of what are called public and private keys.
  • Keys are random numbers chosen for that session and are only known between your browser and our server. Once keys are exchanged, your browser will use the numbers to scramble (encrypt) the messages sent between your browser and our server.
  • Both sides require the keys because they need to descramble (decrypt) messages received. The TLS protocol assures privacy, but also ensures no other website can "impersonate" our website, nor alter information sent.
  • To learn whether your browser is in secure mode, look for the secured lock symbol in your browser window.

Encryption Level

The numbers used as encryption keys are similar to combination locks. The strength of encryption is based on the number of possible combinations a lock can have. The more possible combinations, the less likely someone could guess the combination to decrypt the message.

For your protection, our servers require the browser to connect at 128-bit encryption. Users will be unable to access online banking functions at lesser encryption levels. 

Online Banking Settings

The following settings and plug-ins are required to properly access Online Banking.
  • Cookies Enabled (first- and third-party)
  • JavaScript Enabled
  • Minimum Screen Resolution 1024 x 768 pixels
  • PDF Reader Compatible

Embedded Browsers

Some popular browsers may be embedded into various online services. For example, America Online (AOL) currently uses the popular Internet Explorer browser in its desktop software application. In these cases, although Online Banking may indicate that the core browser is supported, we do not test these embedded browser versions. Due to the lack of testing, we consider these types of browsers unsupported; however users should be able to access most of the functionality assuming that the embedded browser is based on a supported browser.

Supported Browser Summary:

  • Google Chrome
  • Mozilla Firefox
  • Safari 9
  • Internet Explorer 11
  • Microsoft Edge

Supported Browser Details:

Google Chrome & Mozilla Firefox

Google Chrome and Mozilla Firefox are released on extremely rapid release schedules. Because of this, Chrome and Firefox may release new versions of these browsers between releases of Online Banking solutions; however, the content and functionally of these releases are highly unlikely to negatively affect Online Banking. 

Safari (MAC Users only)

Important note about cookies settings: By default, Safari blocks all third-party cookies from being accepted. This setting will cause parts of Online Banking, including FinanceWorks, Bill Pay and other third-party services to function incorrectly. If end users experience any issues accessing these parts of Online Banking using Safari, please verify their cookie settings by going to Safari > Preferences or by hitting ⌘, (Command key plus the comma key) and looking at the Privacy tab. The option for Block cookies should be set to “Never.” 

Internet Explorer and Microsoft Edge

As of January 2016, Microsoft has made significant changes to their support strategy of Internet Explorer. Microsoft will now only support their latest and most current version of Internet Explorer.

What this means is that IE8 and IE9 are no longer versions of IE that will be maintained or updated by Microsoft. Security patches, bugs, enhancements will only be updated on the ‘most current version’ of Internet Explorer. Microsoft has elected to focus their usability and support on their main browser(s) and offers free upgrades to all users. At the time of publication, IE11 and Microsoft Edge are the only browsers being maintained by Microsoft. 

Microsoft Edge is the Default browser for the new Windows 10 Operating System.
