Hi,
Thanks Pauli, the API worked but also I have a callback defined as below which
is failing at corrupt phase:
int SelfTestCb(const OSSL_PARAM params[], void *arg)
{
int ret = 0;
const OSSL_PARAM *p = NULL;
const char *phase = NULL;
const char *type = NULL;
const char *desc = NULL;
//BIO *bio_out = BIO_new_file("FipsSelfTestFile.txt", "w");
p = OSSL_PARAM_locate_const(params, OSSL_PROV_PARAM_SELF_TEST_PHASE);
if ((p == NULL) || (arg) || (p -> data_type != OSSL_PARAM_UTF8_STRING))
goto err;
phase = (const char *)p -> data;
p = OSSL_PARAM_locate_const(params, OSSL_PROV_PARAM_SELF_TEST_DESC);
if ((p == NULL) || (p -> data_type != OSSL_PARAM_UTF8_STRING))
goto err;
desc = (const char *)p -> data;
p = OSSL_PARAM_locate_const(params, OSSL_PROV_PARAM_SELF_TEST_TYPE);
if ((p == NULL) || (p -> data_type != OSSL_PARAM_UTF8_STRING))
goto err;
type = (const char *)p ->data;
/* Do some logging */
if (strcmp(phase, OSSL_SELF_TEST_PHASE_START) == 0)
syslog(LOG_NOTICE, "%s : (%s) : ", desc, type);
if ((strcmp(phase, OSSL_SELF_TEST_PHASE_PASS) == 0)
|| (strcmp(phase, OSSL_SELF_TEST_PHASE_FAIL) ==0))
syslog(LOG_NOTICE, "%s\n", phase);
/* Corrupt the SHA1 self-test during the 'corrupt' phase by returning 0 */
if (strcmp(phase, OSSL_SELF_TEST_PHASE_CORRUPT) == 0){ //
<----------------THIS FAILS
syslog(LOG_NOTICE, "%s %s", phase, desc);
return 0;
}
ret = 1;
err:
return ret;
}
Thanks,
Ashish

Have you considered using the provided for this: OSSL_PROVIDER_self_test()?

Hello All,
I’m trying to execute self-tests that FIPS runs after installation manually by
calling the APIs. I’m using code from
https://github.com/openssl/openssl/blob/7cce994d3e57345ba729388b9321d9bf8b661b4f/providers/fips/self_test_kats.c<https://clicktime.symantec.com/34e4QufezjLGGtyNv3jNidX7GS?u=https%3A%2F%2Fgithub.com%2Fopenssl%2Fopenssl%2Fblob%2F7cce994d3e57345ba729388b9321d9bf8b661b4f%2Fproviders%2Ffips%2Fself_test_kats.c>
but I’m getting NULL when I’m trying to fetch the encryption algorithm. Is
there a way to perform self-tests that FIPS runs after installation because I
did not find any code in fipsinstall.c where it is directly calling the APIs.
