<h1>Bouncy Castle Crypto Package - Release Notes</h1>
</center>
<h2>1.0 Introduction</h2>
<p>
The Bouncy Castle Crypto package is a Java implementation of
cryptographic algorithms. The package is organised so that it
contains a light-weight API suitable for use in any environment
(including the J2ME) with the additional infrastructure
to conform the algorithms to the JCE framework.
</p>
<h2>2.0 Release History</h2>
<a id="r1rv79"><h3>2.1.1 Version</h3></a>
Release: 1.79<br/>
Date: 2024, TBD.
<h3>2.1.2 Defects Fixed</h3>
<ul>
<li>Leading zeroes were sometimes dropped from Ed25519 signatures leading to verification errors in the PGP API. This has been fixed.</li>
</ul>
<h3>2.1.3 Additional Features and Functionality</h3>
<ul>
<li>BCJSSE: Added support for security property "jdk.tls.server.defaultDHEParameters" (disabled in FIPS mode).</li>
</ul>
<a id="r1rv78d1"><h3>2.2.1 Version</h3></a>
Release: 1.78.1<br/>
Date: 2024, 18th April.
<h3>2.2.2 Defects Fixed</h3>
<ul>
<li>The new dependency of the the PGP API on the bcutil jar was missing from the module jar, the OSGi manifest, and the Maven POM. This has been fixed.</li>
<li>Missing exports and duplicate imports have been added/removed from the OSGi manifests.</li>
<li>The OSGi manifests now have the same bundle IDs as 1.77 and lock down dependencies to the equivalent variations.</li>
<li>A check in the X.509 Extensions class preventing the parsing of empty extensions has been removed.</li>
</ul>
<a id="r1rv78"><h3>2.3.1 Version</h3></a>
Release: 1.78<br/>
Date: 2024, 7th April.
<h3>2.3.2 Defects Fixed</h3>
<ul>
<li>Issues with a dangling weak reference causing intermittent NullPointerExceptions in the OcspCache have been fixed.</li>
<li>Issues with non-constant time RSA operations in TLS handshakes have been fixed.</li>
<li>Issue with Ed25519, Ed448 signature verification causing intermittent infinite loop have been fixed.</li>
<li>Issues with non-constant time ML-KEM implementation ("Kyber Slash") have been fixed.</li>
<li>Align ML-KEM input validation with FIPS 203 IPD requirements.</li>
<li>Make PEM parsing more forgiving of whitespace to align with RFC 7468 - Textual Encodings of PKIX, PKCS, and CMS Structures.</li>
<li>Fix CCM length checks with large nonce sizes (n=12, n=13).</li>
<li>EAC: Fixed the CertificateBody ASN.1 type to support an optional Certification Authority Reference in a Certificate Request.</li>
<li>ASN.1: ObjectIdentifier (also Relative OID) parsing has been optimized and the contents octets for both types are now limited to 4096 bytes.</li>
<li>BCJSSE: Fixed a missing null check on the result of PrivateKey.getEncoded(), which could cause issues for HSM RSA keys.</li>
<li>BCJSSE: When endpoint identification is enabled and an SSL socket is not created with an explicit hostname (as happens with HttpsURLConnection), hostname verification could be performed against a DNS-resolved IP address. This has been fixed.</li>
<li>The missing module import of java.logging to the provider module has been added.</li>
<li>GOST ASN.1 public key alg parameters are now compliant with <a href="https://datatracker.ietf.org/doc/rfc9215/">RFC 9215</a>.</li>
<li>An off-by-one error in the encoding for EccP256CurvePoint for ITS has been fixed.</li>
<li>PEM Parser now enforces PEM headers to start at the beginning of the line to be meaningful.</li>
</ul>
<h3>2.3.3 Additional Features and Functionality</h3>
<ul>
<li>An implementation of MLS (<a href="https://datatracker.ietf.org/doc/rfc9420/">RFC 9420 - The Messaging Layer Security Protocol</a>) has been added as a new module.</li>
<li>NTRU now supports NTRU-HPS4096-1229 and NTRU-HRSS-1373.</li>
<li>Improvements to PGP support, including Camellia key wrapping and Curve25519, Curve448 key types (including XDH with HKDF).</li>
<li>Added initial support for ML-KEM in TLS.</li>
<li>Added XWing hybrid KEM construction (X25519 + ML-KEM-768).</li>
<li>Introduced initial KEMSpi support (NTRU, SNTRU Prime) for JDK 21+.</li>
<li>Introduced initial composite signature support for X509 Certificates.</li>
<li>PKCS#12 now supports PKCS12-AES256-AES128, PKCS12-AES256-AES128-GCM, PKCS12-DEF-AES256-AES128, and PKCS12-DEF-AES256-AES128-GCM.</li>
<li>The default type for the KeyStore.getInstance("PKCS12", "BC") can now be set using the org.bouncycastle.pkcs12.default system/security property.</li>
<li>The PGP SExpParser will now handle Ed25519 and Ed448 keys.</li>
<li>Dilithium and Kyber key encoding updated to latest Draft RFCs (<a href="https://datatracker.ietf.org/doc/draft-ietf-lamps-dilithium-certificates/">draft-ietf-lamps-dilithium-certificates</a> and <a href="https://datatracker.ietf.org/doc/draft-ietf-lamps-kyber-certificates/">draft-ietf-lamps-kyber-certificates</a>)</li>
<li>Support has been added for encryption key derivation using HKDF in CMS - see <a href="https://datatracker.ietf.org/doc/draft-housley-lamps-cms-cek-hkdf-sha256/">draft-housley-lamps-cms-cek-hkdf-sha256</a>.</li>
<li>X500Name now recognises jurisdiction{C,ST,L} DNs.</li>
<li>CertPathValidationContext and CertificatePoliciesValidation now include implementations of Memoable.</li>
<li>The Composite post-quantum signatures implementation has been updated to the latest draft <a href="https://datatracker.ietf.org/doc/html/draft-ounsworth-pq-composite-sigs/">draft-ounsworth-pq-composite-sigs</a>.</li>
</ul>
<h3>2.3.4 Notes.</h3>
<ul>
<li>Both versions of NTRUPrime have been updated to produce 256 bit secrets in line with Kyber. This should also bring them into line with other implementations such as those used in OpenSSH now.</li>
<li>BCJSSE: The boolean system property 'org.bouncycastle.jsse.fips.allowRSAKeyExchange" now defaults to false. All RSA
key exchange cipher suites will therefore be disabled when the BCJSSE provider is used in FIPS mode, unless this system
property is explicitly set to true.</li>
<li>OSGi compatibility should now be much improved.</li>
<li>SignedMailValidator now includes a more general rollback method for locating the signature's trust anchor for use when the first approach fails.</li>
<li>The PKCS12 store using GCM does not include the PKCS#12 MAC so no longer includes use of the PKCS#12 PBE scheme and only uses PBKDF2.</li>
<li>In keeping with the current set of experimental OIDs for PQC algorithms, OIDs may have changed to reflect updated versions of the algorithms.</li>
</ul>
<h3>2.3.5 Security Advisories.</h3>
<p>
Release 1.78 deals with the following CVEs:
</p>
<ul>

</ul>
<h3>2.4.4 Notes.</h3>
<ul>
<li>Kyber and Dilithium have been updated according to the latest draft of the standard. Dilithium-AES and Kyber-AES have now been removed. Kyber now produces 256 bit secrets for all parameter sets (in line with the draft standard).</li>
<li>NTRU has been updated to produce 256 bit secrets in line with Kyber.</li>

</ul>
<h3>2.8.4 Security Advisories.</h3>
<ul>
<li>The PQC implementations have now been subject to formal review for secret leakage and side channels, there were issues in BIKE, Falcon, Frodo, HQC which have now been fixed. Some weak positives also showed up in Rainbow, Picnic, SIKE, and GeMSS - for now this last set has been ignored as the algorithms will either be updated if they reappear in the Signature Round, or deleted, as is already the case for SIKE (it is now in the legacy package). Details on the group responsible for the testing can be found in the <a href="../CONTRIBUTORS.html">CONTRIBUTORS</a> file.</li>
<li>For at least some ECIES variants (e.g. when using CBC) there is an issue with potential malleability of a nonce (implying silent malleability of the plaintext) that must be sent alongside the ciphertext but is outside the IES integrity check. For this reason the automatic generation of nonces with IED is now disabled and they have to be passed in using an IESParameterSpec. The current advice is to agree on a nonce between parties and then rely on the use of the ephemeral key component to allow the nonce (rather the so called nonce) usage to be extended.</li>
</ul>
<h3>2.8.5 Notes.</h3>
<ul>
<li>Most test data files have now been migrated to a separate project bc-test-data which is also available on github. If you clone bc-test-data at the same level as the bc-java project the tests will find the test data they require.</li>
<li>There has been further work to make entropy collection more friendly in container environments. See <a hef="https://github.com/bcgit/bc-java/blob/master/prov/src/main/java/org/bouncycastle/jcajce/provider/drbg/DRBG.java">DRBG.java</a> for details. We would welcome any further feedback on this as we clearly cannot try all situations first hand.</li>
