+Restricted tarball tests.
+
+The validated module will have its own tarball containing sufficient code to
+build fipscanister.o and the associated algorithm tests. You can create a
+similar tarball yourself for testing purposes using the commands below.
+
+Standard restricted tarball:
+
+make -f Makefile.fips dist
+
+Prime field field only ECC tarball:
+
+make NOEC2M=1 -f Makefile.fips dist
+
+Once you've created the tarball extract into a fresh directory and do:
+
+./config
+make
+
+You can then run the algorithm tests as above. This build automatically uses
+fipscanisteronly and -DOPENSSL_FIPSYMS and no-ec2m as appropriate.
+
 Known issues:
 
 Algorithm tests are pre-2011.
 The fipslagtest.pl script wont auto run new algorithm tests such as DSA2.
-No ECDH.
-No primitives tests for ECDH/DH
+Usage of ECDH/DH needs review and whether any KDFs need to be implemented.
 Selftests need updating with larger key sizes in some cases and redundant
 tests pruned.
-No SP800-90 PRNG.
-No CMAC.
+SP800-90 DRBG needs more work: check for compliance, continuous PRNG test
+when entropy gathering, periodic health tests.
+Some algorithms need to check security strength of PRNG: keygen etc.
 No CCM.
+No XTS.
+The "FIPS capable OpenSSL" is not yet complete: meaning that the rest of
+OpenSSL doesn't always use the correct FIPS module APIs and block others
+in FIPS mode.
