crypto: kpp - add get/set_flags helpers

2017-07-18T09:50:57+00:00

These helpers will be used for fallbacks to kpp software implementations. Signed-off-by: Tudor Ambarus Signed-off-by: Herbert Xu

crypto: kpp - assume key is already set in maxsize

2017-06-10T04:04:27+00:00

As of now, crypto_kpp_maxsize() can not be reached without successfully setting the key for the transformation. kpp algorithm implementations check if the key was set and then return the output buffer size required for the given key. Change the return type to unsigned int and always assume that this function is called after a successful setkey of the transformation. kpp algorithm implementations will remove the check if key is not NULL and directly return the max size.

crypto: kpp, (ec)dh - fix typos

2017-06-10T04:04:25+00:00

While here, add missing argument description (ndigits). Signed-off-by: Tudor Ambarus Signed-off-by: Herbert Xu

crypto: kpp - constify buffer passed to crypto_kpp_set_secret()

2017-03-09T10:34:27+00:00

Constify the buffer passed to crypto_kpp_set_secret() and kpp_alg.set_secret, since it is never modified. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: doc - add KPP documentation

2016-12-13T23:38:06+00:00

Add the KPP API documentation to the kernel crypto API Sphinx documentation. This addition includes the documentation of the ECDH and DH helpers which are needed to create the approrpiate input data for the crypto_kpp_set_secret function.

crypto: ecdh - Add ECDH software support

2016-06-23T10:29:57+00:00

* Implement ECDH under kpp API * Provide ECC software support for curve P-192 and P-256. * Add kpp test for ECDH with data generated by OpenSSL Signed-off-by: Salvatore Benedetto Signed-off-by: Herbert Xu

crypto: dh - Add DH software implementation

2016-06-23T10:29:56+00:00

* Implement MPI based Diffie-Hellman under kpp API * Test provided uses data generad by OpenSSL Signed-off-by: Salvatore Benedetto Signed-off-by: Herbert Xu

crypto: kpp - Key-agreement Protocol Primitives API (KPP)

2016-06-23T10:29:56+00:00

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
