From 4e5f2c400765e3a3ce512dc1ae890bac53401798 Mon Sep 17 00:00:00 2001 From: Salvatore Benedetto Date: Wed, 22 Jun 2016 17:49:13 +0100 Subject: crypto: kpp - Key-agreement Protocol Primitives API (KPP) 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 Signed-off-by: Herbert Xu --- include/uapi/linux/cryptouser.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include/uapi/linux/cryptouser.h') diff --git a/include/uapi/linux/cryptouser.h b/include/uapi/linux/cryptouser.h index 2e67bb64c1da..79b5ded2001a 100644 --- a/include/uapi/linux/cryptouser.h +++ b/include/uapi/linux/cryptouser.h @@ -45,6 +45,7 @@ enum crypto_attr_type_t { CRYPTOCFGA_REPORT_RNG, /* struct crypto_report_rng */ CRYPTOCFGA_REPORT_CIPHER, /* struct crypto_report_cipher */ CRYPTOCFGA_REPORT_AKCIPHER, /* struct crypto_report_akcipher */ + CRYPTOCFGA_REPORT_KPP, /* struct crypto_report_kpp */ __CRYPTOCFGA_MAX #define CRYPTOCFGA_MAX (__CRYPTOCFGA_MAX - 1) @@ -107,5 +108,9 @@ struct crypto_report_akcipher { char type[CRYPTO_MAX_NAME]; }; +struct crypto_report_kpp { + char type[CRYPTO_MAX_NAME]; +}; + #define CRYPTO_REPORT_MAXSIZE (sizeof(struct crypto_user_alg) + \ sizeof(struct crypto_report_blkcipher)) -- cgit v1.2.3-59-g8ed1b
