NAME

     ENGINE_register_RSA, ENGINE_register_DSA, ENGINE_register_ECDH,
     ENGINE_register_ECDSA, ENGINE_register_DH, ENGINE_register_RAND,
     ENGINE_register_STORE, ENGINE_register_ciphers, ENGINE_register_digests,
     ENGINE_register_complete -- register an ENGINE as implementing an algo-
     rithm


SYNOPSIS

     #include <openssl/engine.h>

     int
     ENGINE_register_RSA(ENGINE *e);

     int
     ENGINE_register_DSA(ENGINE *e);

     int
     ENGINE_register_ECDH(ENGINE *e);

     int
     ENGINE_register_ECDSA(ENGINE *e);

     int
     ENGINE_register_DH(ENGINE *e);

     int
     ENGINE_register_RAND(ENGINE *e);

     int
     ENGINE_register_STORE(ENGINE *e);

     int
     ENGINE_register_ciphers(ENGINE *e);

     int
     ENGINE_register_digests(ENGINE *e);

     int
     ENGINE_register_complete(ENGINE *e);


DESCRIPTION

     In addition to the global table described in ENGINE_add(3), the crypto
     library maintains several tables containing references to ENGINE objects
     implementing one specific cryptographic algorithm.

     The functions listed in the present manual page append e to the end of
     the table for the respective algorithm.

     If e does not contain a method for the requested algorithm, these func-
     tions succeed without having any effect.

     If e is already registered for the given algorithm, they move it to the
     end of the respective table.

     ENGINE_register_ciphers() and ENGINE_register_digests() are special in so
     far as an engine may implement more than one cipher or more than one
     digest.  In that case, e is registered for all the ciphers or digests it
     implements.

     ENGINE_register_complete() registers e for all algorithms it implements
     by calling all the other functions.


RETURN VALUES

     These functions return 1 on success or 0 on error.  They only fail if
     insufficient memory is available.

HISTORY

     ENGINE_register_RSA(), ENGINE_register_DSA(), ENGINE_register_DH(),
     ENGINE_register_RAND(), ENGINE_register_ciphers(),
     ENGINE_register_digests(), and ENGINE_register_complete() first appeared
     in OpenSSL 0.9.7 and have been available since OpenBSD 3.2.

     ENGINE_register_ECDH(), ENGINE_register_ECDSA(), and
     ENGINE_register_STORE() first appeared in OpenSSL 0.9.8 and have been
     available since OpenBSD 4.5.


BUGS

     ENGINE_register_complete() ignores all errors, even memory allocation
     failure, and always returns 1.
