Sorry, I might be not clear enough about the usage of MoreDrbgParameters and
securerandom.drbg.config. You are still using MoreDrbgParameters in
ApiTest.java. For example,
131 SecureRandomParameters mParam = new MoreDrbgParameters(
132 null, mech, alg, nonce, df, (Instantiation)
param);
133 Security.setProperty(DRBG_CONFIG, mech);
134 SecureRandom sr = SecureRandom.getInstance("DRBG",
mParam);
What I wish to see is something like
Security.setProperty(DRBG_CONFIG, mech + "," + alg + ","
+ (df ? "use_df" : "no_df"));
SecureRandom sr = SecureRandom.getInstance("DRBG", param);
So you are still able to iterate through different combinations of mech + alg +
df using a publicly supported API. (Nonce will not be tested, it's not a part
of the API.)
Thanks
