Citibank Bank Account Or Service Complaint

Citibank Bank account or service department,

Other bank product/service Making/receiving payments, sending money Utah

When I made a payment on my Home Depot account serviced by Citi, they required me to agree and accept that my computer was able to encrypt the payment information? I have no idea what this means except that they are possibly hoping that I take on the responsibility that My computer is safe enough to make a payment. I have no idea why this bank would require me to be responsible for the security of my payment - that is their responsibility to make their site safe to make the payment. How would I even know what bit encryption my computer is? This is incredibly unreasonable and confusing, and they refused to take my payment without my agreement. How do companies get away with this? Trying to pass responsibility for their own site safety on to me where I have no idea about any kind of encryption process on my computer? I am so upset by Citi unreasonable demands on consumers at this point I am making sure our Home Depot knows about this and this is really hurting their brand to have this bank called Citi be so abusive to their customers.
