From 94782e0e9c28bd872107b8f814f4db68c9fbf5ab Mon Sep 17 00:00:00 2001 From: Matt Caswell Date: Tue, 26 Mar 2013 15:39:50 +0000 Subject: [PATCH] Make binary curve ASN.1 work in FIPS mode. Don't check for binary curves by checking methods: the values will be different in FIPS mode as they are redirected to the validated module version. --- crypto/ec/ec_ameth.c | 2 +- crypto/ec/ec_asn1.c | 6 ++++-- 2 files changed, 5 insertions(+), 3 deletions(-) diff --git a/crypto/ec/ec_ameth.c b/crypto/ec/ec_ameth.c index 83909c1853..0ce4524076 100644 --- a/crypto/ec/ec_ameth.c +++ b/crypto/ec/ec_ameth.c @@ -88,7 +88,7 @@ static int eckey_param2type(int *pptype, void **ppval, EC_KEY *ec_key) if (!pstr) return 0; pstr->length = i2d_ECParameters(ec_key, &pstr->data); - if (pstr->length < 0) + if (pstr->length <= 0) { ASN1_STRING_free(pstr); ECerr(EC_F_ECKEY_PARAM2TYPE, ERR_R_EC_LIB); diff --git a/crypto/ec/ec_asn1.c b/crypto/ec/ec_asn1.c index 175eec5342..145807b611 100644 --- a/crypto/ec/ec_asn1.c +++ b/crypto/ec/ec_asn1.c @@ -89,7 +89,8 @@ int EC_GROUP_get_trinomial_basis(const EC_GROUP *group, unsigned int *k) if (group == NULL) return 0; - if (EC_GROUP_method_of(group)->group_set_curve != ec_GF2m_simple_group_set_curve + if (EC_METHOD_get_field_type(EC_GROUP_method_of(group)) != + NID_X9_62_characteristic_two_field || !((group->poly[0] != 0) && (group->poly[1] != 0) && (group->poly[2] == 0))) { ECerr(EC_F_EC_GROUP_GET_TRINOMIAL_BASIS, ERR_R_SHOULD_NOT_HAVE_BEEN_CALLED); @@ -107,7 +108,8 @@ int EC_GROUP_get_pentanomial_basis(const EC_GROUP *group, unsigned int *k1, if (group == NULL) return 0; - if (EC_GROUP_method_of(group)->group_set_curve != ec_GF2m_simple_group_set_curve + if (EC_METHOD_get_field_type(EC_GROUP_method_of(group)) != + NID_X9_62_characteristic_two_field || !((group->poly[0] != 0) && (group->poly[1] != 0) && (group->poly[2] != 0) && (group->poly[3] != 0) && (group->poly[4] == 0))) { ECerr(EC_F_EC_GROUP_GET_PENTANOMIAL_BASIS, ERR_R_SHOULD_NOT_HAVE_BEEN_CALLED); -- GitLab
