 The cipher suites can, of course, be a subset of the above.\r
+\r
+General: All crypto should be done via OpenSSL (or another FIPS\r
+certified package). Any external packages using crypto must enable\r
+FIPS mode in OpenSSL. The OpenSSL FIPS security policy must be\r
+followed.\r
+\r
+Note that because Apache sets FIPS mode in OpenSSL, other libraries or\r
+modules using OpenSSL that coexist may exhibit unexpected behaviour\r
+because of the restrictions FIPS mode imposes.\r
+\r
+In particular, only DES, AES, RSA, DSA/DSS and SHA-1 can be\r
+used. There is a special exception that permits the use of MD5 within\r
+TLS, but not elsewhere.\r
