From ec19082eccd008a9aee089696ba346e7316b47f3 Mon Sep 17 00:00:00 2001 From: "Dr. Stephen Henson" Date: Wed, 6 Mar 2013 15:45:15 +0000 Subject: [PATCH] GCM and CCM test support Add code to support GCM an CCM modes in evp_test. On encrypt this will compare the expected ciphertext and tag. On decrypt it will compare the expected plaintext: tag comparison is done internally. Add a simple CCM test case and convert all tests from crypto/modes/gcm128.c (cherry picked from commit 15652f9825de25481676767aa73945409f9c82e2) --- crypto/evp/evp_test.c | 210 +++++++++++++++++++++++++++++++++++++--- crypto/evp/evptests.txt | 23 +++++ 2 files changed, 219 insertions(+), 14 deletions(-) diff --git a/crypto/evp/evp_test.c b/crypto/evp/evp_test.c index 55c7cdfdcc..5289342953 100644 --- a/crypto/evp/evp_test.c +++ b/crypto/evp/evp_test.c @@ -137,11 +137,13 @@ static void test1(const EVP_CIPHER *c,const unsigned char *key,int kn, const unsigned char *iv,int in, const unsigned char *plaintext,int pn, const unsigned char *ciphertext,int cn, + const unsigned char *aad,int an, + const unsigned char *tag,int tn, int encdec) { EVP_CIPHER_CTX ctx; unsigned char out[4096]; - int outl,outl2; + int outl,outl2,mode; printf("Testing cipher %s%s\n",EVP_CIPHER_name(c), (encdec == 1 ?
