Digital Certificates

The right way to make sure the Customer is contacting its Bank and that the Bank is being contacted by the actual customer.


What is a Digital Certificate?

A Digital Certificate, also known as Digital ID, is the electronic equivalent to an Identity Card (I.D.) or Passport. It is a credential issued by a Certificate Authority (C.A.) that Individuals and Companies may present online as proof of their identification or of their right to access information. For the Bank's Companies Website, the certificates are issued by Millennium bcp and enable the institution to, unequivocally, identify its Customers.


What is data encryption?

Data encryption is a way of encoding information so that third parties cannot access the original data sent. This coding is performed mathematically using an algorithm, and the decoding of this data is only possible through the algorithm that generated the coding.


How can I check that a Digital Certificate is authentic?

Using the Internet Explorer browser, just click on the lock that identifies the secure connection and check the data shown, such as the name of the certificate owner, who issued it, validity dates, protocol used, etc.
