receiving a character string;
generating a token for the character string;
encrypting the character string to create an encrypted character string;
storing an association of the token with a sub-string of the character string, wherein the sub-string does not reveal the character string;

responsive to receiving the token:
retrieving, based at least in part on the token, the encrypted character string from the memory;
