Encryption

Encryption


Encryption helps protect your private information (e.g., username and password) so that it cannot be intercepted and read by a third party. Encryption is the scrambling of information for transmission back and forth between two points. A key is required to decode the information. When you request information about your accounts, the request is sent encrypted to Cathay Bank. We then decode your request for information and send it back to you in an encrypted format. When you receive it, your information is decoded so only you can read it.

Cathay Bank employs digital certificates to encrypt the connections between your computer or smartphone and our electronic banking system. This is consistent to the best security practices and employs strong encryption algorithms like RSA-2048 bits.

 

What you can do to protect your connections with Cathay Bank

  1. Always access the encrypted version (https) of Cathay Bank websites. 
  2. Regularly install the recommended operating system updates and patches. Vendors periodically update browsers to support additional encryption algorithms and enhanced key length.
  3. To access electronic banking websites, type the address (URL) in your browser instead of following links. Use official app stores to install mobile apps; avoid downloading from unknown sources as they may contain malware. 
  4. Avoid using public computers or public Wi-Fi to access your financial accounts. Access from trusted computers you know that have security features installed and updated.
