Claim 11:
12. A computer-implemented method comprising:
receiving, by a computing device, a character string;
generating, by the computing device, a token for the character string;
encrypting, by the computing device, the character string to create an encrypted character string;
storing, by the computing device, the encrypted character string to a memory;
storing, by the computing device, an association of the token with a sub-string of the character string, wherein the sub-string does not reveal the character string;
receiving, by the computing device and from a client device during the client device processing part of a network-based transaction using the sub-string in lieu of the character string, a request that includes the token;
responsive to receiving the request:
retrieving, by the computing device and based at least in part on the token, the encrypted character string from the memory;
decrypting, by the computing device, the encrypted character string to create the character string; and
communicating, by the computing device, the character string to the client device, wherein the client device is configured to process the a remainder of the network-based transaction using the character string.
