It provides the primitives required for implementing the protocol, thus the name KPP (Key-agreement Protocol Primitives). Regards, Salvatore Changes from v4: * If fips_enabled is set allow only P256 (or higher) as Stephan suggested * Pass ndigits as argument to ecdh_make_pub_key and ecdh_shared_secret so that VLA can be used like in the rest of the module Changes from v3: * Move curve ID definition to public header ecdh.h as users need to have access to those ids when selecting the curve Changes from v2: * Add support for ECDH (curve P192 and P256). I reused the ecc module already present in net/bluetooth and extended it in order to select different curves at runtime. Code for P192 was taken from tinycrypt. Changes from v1: * Change check in dh_check_params_length based on Stephan review Salvatore Benedetto (3): crypto: Key-agreement Protocol Primitives API (KPP) crypto: kpp - Add DH software implementation crypto: kpp - Add ECDH software support crypto/Kconfig | 23 + crypto/Makefile | 6 + crypto/crypto_user.c | 20 + crypto/dh.c | 224 +++++++++ crypto/ecc.c | 1016 +++++++++++++++++++++++++++++++++++++++ crypto/ecc.h | 70 +++ crypto/ecc_curve_defs.h | 57 +++ crypto/ecdh.c | 171 +++++++ crypto/kpp.c | 123 +++++ crypto/testmgr.c | 275 +++++++++++ crypto/testmgr.h | 281 +++++++++++ include/crypto/dh.h | 23 + include/crypto/ecdh.h | 24 + include/crypto/internal/kpp.h | 64 +++ include/crypto/kpp.h | 333 +++++++++++++ include/linux/crypto.h | 1 + include/uapi/linux/cryptouser.h | 5 + 17 files changed, 2716 insertions(+) create mode 100644 crypto/dh.c create mode 100644 crypto/ecc.c create mode 100644 crypto/ecc.h create mode 100644 crypto/ecc_curve_defs.h create mode 100644 crypto/ecdh.c create mode 100644 crypto/kpp.c create mode 100644 include/crypto/dh.h create mode 100644 include/crypto/ecdh.h create mode 100644 include/crypto/internal/kpp.h create mode 100644 include/crypto/kpp.h -- 1.9.1
