1. A method of generating a seed value for use in symmetric encryption, the method comprising the computer-implemented steps of:

  • (a) creating and storing a first data set;

    (b) generating a hashed value based on the first data set;

    (c) selecting, based on a time-based value associated with the step of generating the hashed value, a replacement position in the first data set;

    (d) writing at least a portion of the hashed value into the first data set at the replacement position;

    (e) selecting, as the seed value, a seed portion of the first data set;

    (f) generating a symmetric encryption key based on the seed value; and

    (g) encrypting, using the symmetric encryption key, data communicated to a computer system.
