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/linux/crypto.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/linux') diff --git a/include/linux/crypto.h b/include/linux/crypto.h index d844cbc365f7..992cfc2e5df1 100644 --- a/include/linux/crypto.h +++ b/include/linux/crypto.h @@ -48,6 +48,7 @@ #define CRYPTO_ALG_TYPE_BLKCIPHER 0x00000004 #define CRYPTO_ALG_TYPE_ABLKCIPHER 0x00000005 #define CRYPTO_ALG_TYPE_GIVCIPHER 0x00000006 +#define CRYPTO_ALG_TYPE_KPP 0x00000008 #define CRYPTO_ALG_TYPE_RNG 0x0000000c #define CRYPTO_ALG_TYPE_AKCIPHER 0x0000000d #define CRYPTO_ALG_TYPE_DIGEST 0x0000000e -- cgit From 9b45b7bba3d22de52e09df63c50f390a193a3f53 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 29 Jun 2016 19:32:21 +0800 Subject: crypto: rsa - Generate fixed-length output Every implementation of RSA that we have naturally generates output with leading zeroes. The one and only user of RSA, pkcs1pad wants to have those leading zeroes in place, in fact because they are currently absent it has to write those zeroes itself. So we shouldn't be stripping leading zeroes in the first place. In fact this patch makes rsa-generic produce output with fixed length so that pkcs1pad does not need to do any extra work. This patch also changes DH to use the new interface.

They are accessible through the top-level skcipher interface, along with ablkcipher/blkcipher algorithms and instances. This patch also introduces a new parameter called chunk size which is meant for ciphers such as CTR and CTS which ostensibly can handle arbitrary lengths, but still behave like block ciphers in that you can only process a partial block at the very end. For these ciphers the block size will continue to be set to 1 as it is now while the chunk size will be set to the underlying block size.
