From 03d7db5654aefb78bf2ded62e2187833fda2a6cc Mon Sep 17 00:00:00 2001 From: Corentin LABBE Date: Fri, 19 May 2017 08:53:23 +0200 Subject: crypto: hmac - add hmac IPAD/OPAD constant Many HMAC users directly use directly 0x36/0x5c values. It's better with crypto to use a name instead of directly some crypto constant. This patch simply add HMAC_IPAD_VALUE/HMAC_OPAD_VALUE defines in a new include file "crypto/hmac.h" and use them in crypto/hmac.c Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu --- include/crypto/hmac.h | 7 +++++++ 1 file changed, 7 insertions(+) create mode 100644 include/crypto/hmac.h (limited to 'include/crypto/hmac.h') diff --git a/include/crypto/hmac.h b/include/crypto/hmac.h new file mode 100644 index 000000000000..ef09f7938204 --- /dev/null +++ b/include/crypto/hmac.h @@ -0,0 +1,7 @@ +#ifndef _CRYPTO_HMAC_H +#define _CRYPTO_HMAC_H + +#define HMAC_IPAD_VALUE 0x36 +#define HMAC_OPAD_VALUE 0x5c + +#endif /* _CRYPTO_HMAC_H */ -- cgit v1.2.3
