+ This chapter describes FIPS mode support in the crypto application.
+ </p>
+
+ <section>
+ <title>Background</title>
+ <p>OpenSSL can be built to provide FIPS 140-2 validated
+ cryptographic services. It is not the OpenSSL application that is
+ validated, but a special software component called the OpenSSL
+ FIPS Object Module. However applications do not use this Object
+ Module directly, but through the regular API of the OpenSSL
+ library.</p>
+ <p>The crypto application supports using OpenSSL in FIPS mode. In
+ this scenario only the validated algorithms provided by the Object
+ Module are accessible, other algorithms usually available in
+ OpenSSL (like md5) or implemented in the Erlang code (like SRP)
+ are disabled.</p>
+ </section>
+
+ <section>
+ <title>Enabling FIPS mode</title>
+ <list type="ordered">
+ <item>
+ <p>Build or install the FIPS Object Module and a FIPS enabled
+ OpenSSL library.</p>
+ <p>You should read and precisely follow the instructions of
+ the <url
+ href="http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp1747.pdf">Security
+ Policy</url> and <url
+ href="https://www.openssl.org/docs/fips/UserGuide-2.0.pdf">User
+ Guide</url>.</p>
+ <warning><p>It is very easy to build a working OpenSSL FIPS
+ Object Module and library from the source. However it <em>does
+ not</em> qualify as FIPS 140-2 validated if the numerous
+ restrictions in the Security Policy are not properly
+ followed.</p></warning>
+ </item>
+ <item>
+ <p>Configure and build Erlang/OTP with FIPS support:</p>
+ <pre>
+$ <input>cd $ERL_TOP</input>
+$ <input>./otp_build configure --enable-fips</input>
+...
+checking for FIPS_mode_set... yes
+...
+$ <input>make</input>
+ </pre>
+ <p>If <c>FIPS_mode_set</c> returns <c>no</c> the OpenSSL
+ library is not FIPS enabled and crypto won't support FIPS mode
+ either.</p>
+ </item>
+ <item>
+ <p>Set the <c>fips_mode</c> configuration setting of the
+ crypto application to <c>true</c> <em>before loading the
+ crypto module</em>.</p>
+ <p>The best place is in the <c>sys.config</c> system
+ configuration file of the release.</p>
+ </item>
+ <item>
+ Start and use the crypto application as usual. However take
+ care to avoid the non-FIPS validated algorithms, they will all
+ throw exception <c>not_supported</c>.
+ </item>
+ </list>
+ <p>Entering and leaving FIPS mode on a node already running crypto
+ is not supported. The reason is that OpenSSL is designed to
+ prevent an application requesting FIPS mode to end up accidentally
+ running in non-FIPS mode. If entering FIPS mode fails (e.g. the
+ Object Module is not found or is compromised) any subsequent use
+ of the OpenSSL API would terminate the emulator.</p>
+ <p>An on-the-fly FIPS mode change would thus have to be performed
+ in a critical section protected from any concurrently running
+ crypto operations. Furthermore in case of failure all crypto calls
+ would have to be disabled from the Erlang or nif code. This would
+ be too much effort put into this not too important feature.</p>
+ </section>
+
+ <section>
+ <title>Incompatibilities with regular builds</title>
+ <p>The Erlang API of the crypto application is identical
+ regardless of building with or without FIPS support. However the
+ nif code internally uses a different OpenSSL API.</p>
+ <p>This means that the context (an opaque type) returned from
+ streaming crypto functions (<c>hash_(init|update|final)</c>,
+ <c>hmac_(init|update|final)</c> and
+ <c>stream_(init|encrypt|decrypt)</c>) is different and
+ incompatible with regular builds when compiling crypto with FIPS
+ support.</p>
+ </section>
+
+ <section>
+ <title>Common caveats</title>
+ <p>In FIPS mode non-validated algorithms are disabled. This may
+ cause some unexpected problems in application relying on
+ crypto.</p>
+ <warning><p>Do not try to work around these problems by using
+ alternative implementations of the missing algorithms! An
+ application can only claim to be using a FIPS 140-2 validated
+ cryptographic module if it uses it exclusively for every
+ cryptographic operation.</p></warning>
+
+ <section>
+ <title>Restrictions on key sizes</title>
+ <p>Although public key algorithms are supported in FIPS mode
+ they can only be used with secure key sizes. The Security Policy
+ requires the following minimum values:
+ </p>
+ <taglist>
+ <tag>RSA</tag><item>1024 bit</item>
+ <tag>DSS</tag><item>1024 bit</item>
+ <tag>EC algorithms</tag><item>160 bit</item>
+ </taglist>
+ </section>
+
+ <section>
+ <title>Restrictions on elliptic curves</title>
+ <p>The Erlang API allows using arbitrary curve parameters, but
+ in FIPS mode only those allowed by the Security Policy shall be
+ used.</p>
+ </section>
+
+ <section>
+ <title>Avoid md5 for hashing</title>
+ <p>Md5 is a popular choice as a hash function, but it is not
+ secure enough to be validated. Try to use sha instead wherever
+ possible.</p>
+ <p>For exceptional, non-cryptographic use cases one may consider
+ switching to <c>erlang:md5/1</c> as well.</p>
+ </section>
+
+ <section>
+ <title>Certificates and encrypted keys</title>
+ <p>As md5 is not available in FIPS mode it is only possible to
+ use certificates that were signed using sha hashing. When
+ validating an entire certificate chain all certificates
+ (including the root CA's) must comply with this rule.</p>
+ <p>For similar dependency on the md5 and des algorithms most
+ encrypted private keys in PEM format do not work
+ either. However, the PBES2 encryption scheme allows the use of
+ stronger FIPS verified algorithms which is a viable
+ alternative.</p>
+ </section>
+
+ <section>
+ <title>SNMP v3 limitations</title>
+ <p>It is only possible to use <c>usmHMACSHAAuthProtocol</c> and
+ <c>usmAesCfb128Protocol</c> for authentication and privacy
+ respectively in FIPS mode. The snmp application however won't
+ restrict selecting disabled protocols in any way, and using them
+ would result in run time crashes.</p>
+ </section>
+
+ <section>
+ <title>TLS 1.2 is required</title>
+ <p>All SSL and TLS versions prior to TLS 1.2 use a combination
+ of md5 and sha1 hashes in the handshake for various purposes:</p>
+ <list>
+ <item>Authenticating the integrity of the handshake
+ messages.</item>
+ <item>In the exchange of DH parameters in cipher suites
+ providing non-anonymous PFS (perfect forward secrecy).</item>
+ <item>In the PRF (pseud-random function) to generate keying
+ materials in cipher suites not using PFS.</item>
+ </list>
+ <p>OpenSSL handles these corner cases in FIPS mode, however the
+ Erlang crypto and ssl applications are not prepared for them and
+ therefore you are limited to TLS 1.2 in FIPS mode.</p>
+ <p>On the other hand it worth mentioning that at least all
+ cipher suites that would rely on non-validated algorithms are
+ automatically disabled in FIPS mode.</p>
+ <note><p>Certificates using weak (md5) digests may also cause
+ problems in TLS. Although TLS 1.2 has an extension for
+ specifying which type of signatures are accepted, and in FIPS
+ mode the ssl application will use it properly, most TLS
+ implementations ignore this extension and simply send whatever
+ certificates they were configured with.</p></note>
