Subject: [PATCH v12 05/10] ecdsa: Register NIST P384 and extend test suite
From: Saulo Alessandre <saulo.alessandre@....jus.br>
Register NIST P384 as an akcipher and extend the testmgr with
NIST P384-specific test vectors.
Summary of changes:
* crypto/ecdsa.c
- add ecdsa_nist_p384_init_tfm
- register and unregister P384 tfm
* crypto/testmgr.c
- add test vector for P384 on vector of tests
* crypto/testmgr.h
- add test vector params for P384(sha1, sha224, sha256, sha384
and sha512)
