From e9a910b33c7837b4b868e3abda18eb4810df7f02 Mon Sep 17 00:00:00 2001 From: Leah Rowe Date: Sat, 4 Oct 2025 09:14:33 +0100 Subject: config/git: import suckless sbase i currently use the output of sha512sum in several places of xbmk, which is a bit unreliable in case output changes. other cases where i use util outputs in variables are probably reliable, because i'm using mostly posix utilities in those. to mitigate this, i now import suckless sbase, which has a reasonable sha512sum implementation. *every* binary it builds is being placed in build.list, because i'll probably start using more of them. for example, i may start modifying the "date" implementation, adding the GNU-specific options that i need as mentioned on init.sh i'm importing it in util/ because the sha512sum util is needed for verifying project sources, so if sbase itself is a "project source", that means we can into a chicken and egg bootstrapping problem. this is sbase at revision: 055cc1ae1b3a13c3d8f25af0a4a3316590efcd48 Signed-off-by: Leah Rowe --- util/sbase/sha512-224.h | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) create mode 100644 util/sbase/sha512-224.h (limited to 'util/sbase/sha512-224.h') diff --git a/util/sbase/sha512-224.h b/util/sbase/sha512-224.h new file mode 100644 index 00000000..8364fc5f --- /dev/null +++ b/util/sbase/sha512-224.h @@ -0,0 +1,16 @@ +/* public domain sha512/224 implementation based on fips180-3 */ + +#include "sha512.h" + +#define sha512_224 sha512 /*struct*/ + +enum { SHA512_224_DIGEST_LENGTH = 28 }; + +/* reset state */ +void sha512_224_init(void *ctx); +/* process message */ +#define sha512_224_update sha512_update +/* get message digest */ +/* state is ruined after sum, keep a copy if multiple sum is needed */ +/* part of the message might be left in s, zero it if secrecy is needed */ +void sha512_224_sum(void *ctx, uint8_t md[SHA512_224_DIGEST_LENGTH]); -- cgit v1.2.1
