Ddigsig.rst19 Digital signature verification API provides a method to verify digital signature.
22 Digital signature verification is implemented using cut-down kernel port of
27 Public key and signature consist of header and MPIs::
38 uint8_t version; /* signature format version */
39 time_t timestamp; /* signature made */
48 Signature header is used as an input to generate a signature.
49 Such approach insures that key or signature header could not be changed.
