From 5ca4c20cfd37bac6486de040e9951b3b34755238 Mon Sep 17 00:00:00 2001 From: Jarkko Sakkinen Date: Thu, 5 Nov 2015 21:43:06 +0200 Subject: keys, trusted: select hash algorithm for TPM2 chips Added 'hash=' option for selecting the hash algorithm for add_key() syscall and documentation for it. Added entry for sm3-256 to the following tables in order to support TPM_ALG_SM3_256: * hash_algo_name * hash_digest_size Includes support for the following hash algorithms: * sha1 * sha256 * sha384 * sha512 * sm3-256 Signed-off-by: Jarkko Sakkinen Tested-by: Colin Ian King Reviewed-by: James Morris Reviewed-by: Mimi Zohar Acked-by: Peter Huewe --- crypto/hash_info.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'crypto/hash_info.c') diff --git a/crypto/hash_info.c b/crypto/hash_info.c index 3e7ff46f26e8..7b1e0b188ce6 100644 --- a/crypto/hash_info.c +++ b/crypto/hash_info.c @@ -31,6 +31,7 @@ const char *const hash_algo_name[HASH_ALGO__LAST] = { [HASH_ALGO_TGR_128] = "tgr128", [HASH_ALGO_TGR_160] = "tgr160", [HASH_ALGO_TGR_192] = "tgr192", + [HASH_ALGO_SM3_256] = "sm3-256", }; EXPORT_SYMBOL_GPL(hash_algo_name); @@ -52,5 +53,6 @@ const int hash_digest_size[HASH_ALGO__LAST] = { [HASH_ALGO_TGR_128] = TGR128_DIGEST_SIZE, [HASH_ALGO_TGR_160] = TGR160_DIGEST_SIZE, [HASH_ALGO_TGR_192] = TGR192_DIGEST_SIZE, + [HASH_ALGO_SM3_256] = SM3256_DIGEST_SIZE, }; EXPORT_SYMBOL_GPL(hash_digest_size); -- cgit v1.2.3
