Title:
EC_KEY_generate_key() causes FIPS self-test failure
Status in openssl package in Ubuntu:
New
Bug description:
EC_KEY_generate_key() internally calls fips_pkey_signature_test()
which performs a pairwise check by ECDSA signing/verifying, but some
groups don't support ECDSA.
For example, `openssl ecparam -genkey -name Oakley-EC2N-4` fails.
Unfortunately `openssl ecparam` doesn't give any useful information so
I modified a bit:
~~~
diff --git a/apps/ecparam.c b/apps/ecparam.c
index 71b67f4..db89c2f 100644
--- a/apps/ecparam.c
+++ b/apps/ecparam.c
@@ -585,6 +585,7 @@ int MAIN(int argc, char **argv)
if (!EC_KEY_generate_key(eckey)) {
EC_KEY_free(eckey);
+ ERR_print_errors(bio_err);
goto end;
}
if (outformat == FORMAT_ASN1)
~~~
And I got:
~~~
