     These functions are used to encrypt and decrypt data.

     kkrrbb55__eennccrryypptt() puts the encrypted version of _d_a_t_a (of size _l_e_n) in
     _r_e_s_u_l_t. If the encryption type supports using derived keys, _u_s_a_g_e should
     be the appropriate key-usage.  kkrrbb55__eennccrryypptt__EEnnccrryypptteeddDDaattaa() does the same
     as kkrrbb55__eennccrryypptt(), but it puts the encrypted data in a _E_n_c_r_y_p_t_e_d_D_a_t_a
     structure instead. If _k_v_n_o is not zero, it will be put in the _k_v_n_o _f_i_e_l_d
     _i_n _t_h_e _E_n_c_r_y_p_t_e_d_D_a_t_a.

     kkrrbb55__ddeeccrryypptt(), and kkrrbb55__ddeeccrryypptt__EEnnccrryypptteeddDDaattaa() works similarly.
