1. A method for cryptographic processing of data using a network device that is operative to perform actions, comprising:

  • responsive to receiving a request to rotate at least one current key, performing further actions, including;

    generating at least one transitional key by encrypting the at least one current key using at least one system key;

    generating at least one new key based on at least one determined key parameter;

    activating the at least one new key based on data provided by at least two key holders, wherein the provided data includes at least a password provided by each key holder and a portion of keying data provided by each key holder, wherein the at least portion of keying data is based on at least one of seeding data, or entropy data;

    generating at least one new current key based on the at least one activated key, wherein the at least one new current key is stored at least in volatile memory; and

    encrypting the at least one transitional key using the at least one new current key and storing it in at least one key array.
