Peer-to-peer authentication may be accomplished by sending a digital certificate to a responder, receiving a randomized codeword in response to the sending, creating a secure fingerprint based at least in part on the digital certificate and randomized codeword, creating a first bit sequence based at least in part on a first portion of the secure fingerprint and a second portion of the randomized codeword and indicating the first digital certificate is authenticated based upon whether the first bit sequence matches a second bit sequence received from the responder via an out-of-band communication in response to the sending. The size of the first bit sequence is less than the size of the secure fingerprint. According to another aspect, the first bit sequence is compared with a rendering of the second bit sequence, using an out-of-band communication, by associating the first bit sequence with one or more indices into an array of representations.
