To find out what level of encryption your browser supports, and to download the proper version if necessary, check here. The methods are outlined below. Digital Ids from VeriSign Butte Community Bank's IBS system uses digital IDs certified by VeriSign, an industry leader in digital identification certificates, to authenticate user information and provide access to the data through the system. A digital ID requires a matched pair of keys that are unique to each other to encrypt and decrypt data. With this setup, transactions created, encrypted, and transmitted by bank customers using the public key can only be decrypted by the other key in the pair running on the server.
Encryption strength is measured by the size of the numbers used in the keys.
With SSL, data traveling between the bank and customer is encrypted and can only be decrypted through the pairing of the public and private key pair. SSL capability is built into server hardware and browsers, but requires a digital ID to be functional. Server Access Server access is protected using a firewall computer and the leading firewall software, CheckPoint's Firewall-1. Firewall computers provide secure access to the Web Server and Checkpoint's software by only allowing authorized traffic to hit the Server. The Math Behind Encryption Let s try and put this whole encryption thing in perspective.
