From 541bf464a0b5849e0823d075a2403eeb37f90ea9 Mon Sep 17 00:00:00 2001 From: Vitaly Chikunov Date: Sat, 9 May 2020 06:57:12 +0300 Subject: [PATCH] test_ciphers: Add Magma CTR (and CBC) test(s) - CTR vector is from standard. - CBC vector is generated by PR_GOSTR_bch_v9. CBC test fail in-place decryption, so it's disabled by `#if 0'. --- test_ciphers.c | 92 +++++++++++++++++++++++++++++++++++++++++++------- 1 file changed, 79 insertions(+), 13 deletions(-) diff --git a/test_ciphers.c b/test_ciphers.c index b68be78..95e3e99 100644 --- a/test_ciphers.c +++ b/test_ciphers.c @@ -31,20 +31,43 @@ else \ printf(cGREEN "Test passed\n" cNORM);} -/* Test key from both GOST R 34.12-2015 and GOST R 34.13-2015. */ +/* Pragma to allow commenting out some tests. */ +#pragma GCC diagnostic ignored "-Wunused-const-variable" + +/* + * Test keys from both GOST R 34.12-2015 and GOST R 34.13-2015, + * for 128-bit cipher (A.1). + */ static const unsigned char K[32] = { 0x88,0x99,0xaa,0xbb,0xcc,0xdd,0xee,0xff,0x00,0x11,0x22,0x33,0x44,0x55,0x66,0x77, 0xfe,0xdc,0xba,0x98,0x76,0x54,0x32,0x10,0x01,0x23,0x45,0x67,0x89,0xab,0xcd,0xef, };
