From 95f25c355fc13727410ccacaa618caf6af5d5eba Mon Sep 17 00:00:00 2001 From: Sergio Correia Date: Mon, 3 May 2021 22:36:36 -0300 Subject: [PATCH] sss: use BN_set_word(x, 0) instead of BN_zero() Different OpenSSL versions define BN_zero() differently -- sometimes returning an integer, sometimes as void --, so let's use instead BN_set_word() instead, not to have issues when building with these different versions. --- src/pins/sss/sss.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/pins/sss/sss.c b/src/pins/sss/sss.c index a37215d..7486d6c 100644 --- a/src/pins/sss/sss.c +++ b/src/pins/sss/sss.c @@ -214,7 +214,7 @@ sss_point(const json_t *sss, size_t *len) if (BN_rand_range(xx, pp) <= 0) return NULL; - if (BN_zero(yy) <= 0) + if (BN_set_word(yy, 0) <= 0) return NULL; for (size_t i = 0; i < json_array_size(e); i++) { @@ -272,7 +272,7 @@ sss_recover(const json_t *p, size_t npnts, const uint8_t *pnts[]) if (!ctx || !pp || !acc || !tmp || !k) return NULL; - if (BN_zero(k) <= 0) + if (BN_set_word(k, 0) <= 0) return NULL; len = jose_b64_dec(p, NULL, 0); @@ -303,7 +303,7 @@ sss_recover(const json_t *p, size_t npnts, const uint8_t *pnts[]) /* acc *= (0 - xi) / (xo - xi) */ - if (BN_zero(tmp) <= 0) + if (BN_set_word(tmp, 0) <= 0) return NULL; if (BN_mod_sub(tmp, tmp, xi, pp, ctx) <= 0) -- 2.31.1
