From 30f77cdfc17e1a5dcac52f280c44b4ed87c79286 Mon Sep 17 00:00:00 2001 From: Gilles Peskine Date: Mon, 14 Jan 2019 16:06:39 +0100 Subject: [PATCH] Add a hash wildcard value for hash-and-sign algorithm You can use PSA_ALG_ANY_HASH to build the algorithm value for a hash-and-sign algorithm in a policy. Then the policy allows usage with this hash-and-sign family with any hash. Test that PSA_ALG_ANY_HASH-based policies allow a specific hash, but not a different hash-and-sign family. Test that PSA_ALG_ANY_HASH is not valid for operations, only in policies. --- include/psa/crypto_values.h | 64 +++++++++++++++++++ library/psa_crypto.c | 27 +++++++- tests/suites/test_suite_psa_crypto.data | 50 ++++++++++++--- tests/suites/test_suite_psa_crypto.function | 18 ++++-- .../test_suite_psa_crypto_metadata.data | 24 +++++++ .../test_suite_psa_crypto_metadata.function | 13 ++++ 6 files changed, 180 insertions(+), 16 deletions(-) diff --git a/include/psa/crypto_values.h b/include/psa/crypto_values.h index a4257da3d..f072487f2 100644 --- a/include/psa/crypto_values.h +++ b/include/psa/crypto_values.h @@ -641,6 +641,7 @@ (((alg) & PSA_ALG_CATEGORY_MASK) == PSA_ALG_CATEGORY_KEY_SELECTION) #define PSA_ALG_HASH_MASK ((psa_algorithm_t)0x000000ff) + #define PSA_ALG_MD2 ((psa_algorithm_t)0x01000001) #define PSA_ALG_MD4 ((psa_algorithm_t)0x01000002) #define PSA_ALG_MD5 ((psa_algorithm_t)0x01000003) @@ -667,6 +668,41 @@ /** SHA3-512 */ #define PSA_ALG_SHA3_512 ((psa_algorithm_t)0x01000013) +/** Allow any hash algorithm. + * + * This value may only be used to form the algorithm usage field of a policy + * for a signature algorithm that is parametrized by a hash.
