 ** symkeyutil.c

 **

 ** utility for managing symetric keys in the database or the token

 **

 */

 /*

  * Wish List for this utility:

  *  1) Display and Set the CKA_ operation flags for the key.

  *  2) Modify existing keys

  *  3) Copy keys

  *  4) Read CKA_ID and display for keys.

  *  5) Option to store CKA_ID in a file on key creation.

  *  6) Encrypt, Decrypt, Hash, and Mac with generated keys.

  *  7) Use asymetric keys to wrap and unwrap keys.

  *  8) Derive.

  *  9) PBE keys.
