2016-06-23crypto: kpp - Key-agreement Protocol Primitives API (KPP)Salvatore Benedetto1-0/+5
Add key-agreement protocol primitives (kpp) API which allows to implement primitives required by protocols such as DH and ECDH. The API is composed mainly by the following functions * set_secret() - It allows the user to set his secret, also referred to as his private key, along with the parameters known to both parties involved in the key-agreement session. * generate_public_key() - It generates the public key to be sent to the other counterpart involved in the key-agreement session. The function has to be called after set_params() and set_secret() * generate_secret() - It generates the shared secret for the session Other functions such as init() and exit() are provided for allowing cryptographic hardware to be inizialized properly before use Signed-off-by: Salvatore Benedetto <salvatore.benedetto@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-06-22crypto: user - Add CRYPTO_MSG_DELRNGHerbert Xu1-0/+1
This patch adds a new crypto_user command that allows the admin to delete the crypto system RNG. Note that this can only be done if the RNG is currently not in use. The next time it is used a new system RNG will be allocated. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
