From 02e79a4e4388e26a724173b5ee7b7d098e4aabad Mon Sep 17 00:00:00 2001 From: Gilles Peskine Date: Mon, 7 Oct 2019 17:06:06 +0200 Subject: [PATCH] MBEDTLS_CTR_DRBG_USE_128_BIT_KEY: add selftest data In the CTR_DRBG module, add selftest data for when MBEDTLS_CTR_DRBG_USE_128_BIT_KEY is enabled. I generated the test data by running our own code. This is ok because we have other tests that ensure that the algorithm is implemented correctly. This makes programs/self/selftest pass when MBEDTLS_CTR_DRBG_USE_128_BIT_KEY is enabled. --- library/ctr_drbg.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/library/ctr_drbg.c b/library/ctr_drbg.c index 047bb2a3e..b6fcc0203 100644 --- a/library/ctr_drbg.c +++ b/library/ctr_drbg.c @@ -712,6 +712,15 @@ static const unsigned char nonce_pers_nopr[16] = { 0x1b, 0x54, 0xb8, 0xff, 0x06, 0x42, 0xbf, 0xf5, 0x21, 0xf1, 0x5c, 0x1c, 0x0b, 0x66, 0x5f, 0x3f }; +#if defined(MBEDTLS_CTR_DRBG_USE_128_BIT_KEY) +static const unsigned char result_pr[16] = + { 0x95, 0x3c, 0xa5, 0xbd, 0x44, 0x1, 0x34, 0xb7, + 0x13, 0x58, 0x3e, 0x6a, 0x6c, 0x7e, 0x88, 0x8a }; + +static const unsigned char result_nopr[16] = + { 0x6c, 0x25, 0x27, 0x95, 0xa3, 0x62, 0xd6, 0xdb, + 0x90, 0xfd, 0x69, 0xb5, 0x42, 0x9, 0x4b, 0x84 }; +#else /* MBEDTLS_CTR_DRBG_USE_128_BIT_KEY */ static const unsigned char result_pr[16] = { 0x34, 0x01, 0x16, 0x56, 0xb4, 0x29, 0x00, 0x8f, 0x35, 0x63, 0xec, 0xb5, 0xf2, 0x59, 0x07, 0x23 }; @@ -719,6 +728,7 @@ static const unsigned char result_pr[16] = static const unsigned char result_nopr[16] = { 0xa0, 0x54, 0x30, 0x3d, 0x8a, 0x7e, 0xa9, 0x88, 0x9d, 0x90, 0x3e, 0x07, 0x7c, 0x6f, 0x21, 0x8f }; +#endif /* MBEDTLS_CTR_DRBG_USE_128_BIT_KEY */ static size_t test_offset; static int ctr_drbg_self_test_entropy( void *data, unsigned char *buf,
