/* This structure is required to tie the message digest and signing together.

 * The lookup can be done by md/pkey_method, oid, oid/pkey_method, or

 * oid, md and pkey.

 * This is required because for various smart-card perform the digest and

 * signing/verification on-board.  To handle this case, the specific

 * EVP_MD and EVP_PKEY_METHODs need to be closely associated.

 * When a PKEY is created, it will have a EVP_PKEY_METHOD associated with it.

 * This can either be software or a token to provide the required low level

 * routines.
