Latest Java Releases

Release 1.71 is now available for download.

This is primarily a feature release, with the feature being the expansion of our post-quantum algorithms to include the NIST finalists and alternate candidates. This release adds SPHINCS+, Classic McEliece, FrodoKEM and SABER to the BCPQC provider. The basic SHA-3 Derived Functions: KMAC, TupleHash and ParallelHash have also been added to the BC provider, in addition to Blake3-256. The OpenPGP API now supports insertion or replacement of PGP public keys in secret key rings, joing/merging of PGP public keys/signatures and the RegExp and PolicyURI signature sub-packets have been added. Signed message generation and verification, as well as generation of certification requests have been added to the ETSI/ITS packages. Additional validations have also been added for both RSA and EC keys and upper bounds on parameter sizes for both algorithms have been introduced. Support has been addd for additional input in deterministic (EC)DSA. In bug fixes, JcaPKIXIdentityBuilder file handling has been fixed, byte[] parameters in the CMP API are now defensively cloned, the fall back mode of the JCE key wrapping operators now ensures the original parameters are preserved, and an error in the creation of TLS 1.3 Export Keying Material which could cause compatibility issues have also been fixed.

Further details on other additions and bug fixes can be found in the release notes file accompanying the release.

 

Java Version Details With the arrival of Java 15. jdk15 is not quite as unambiguous as it was. The jdk18on jars are compiled to work with anything from Java 1.8 up. They are also multi-release jars so do support some features that were introduced in Java 9, Java 11, and Java 15. If you have issues with multi-release jars see the jdk15to18 release jars below.

Packaging Change (users of 1.70 or earlier): BC 1.71 changed the jdk15on jars to jdk18on so the base has now moved to Java 8. For earlier JVMs, or containers/applications that cannot cope with multi-release jars, you should now use the jdk15to18 jars.

Packaging Change (users of 1.68 or earlier): BC 1.69 introduced a new jar, bcutil-*.jar, which is a collection of classes which do not need to be in the JCE provider jar, but are used by the other APIs. You will find you will need to add the bcutil jar to the class path if you are using the other BC APIs.

Change Warning (users of 1.68 or earlier): The BKS-V1 KeyStore format is now disabled by default. See releasenotes for 1.69 for details to turn it on if required.

Change Warning (users of 1.52 or earlier): The PEM Parser now returns an X509TrustedCertificate block when parsing an openssl trusted certificate, the new object was required to allow the proper return of the trusted certificate's attribute block. Please also see the porting guide for advice on porting to this release from much earlier ones (release 1.45 or earlier).

Further Note (users of Oracle JVM 1.7 or earlier, users of "pre-Java 9" toolkits): As of 1.63 we have started including signed jars for "jdk15to18", if you run into issues with either signature validation in the JCE or the presence of the multi-release versions directory in the regular "jdk18on" jar files try the "jdk15to18" jars instead. Please also note the JCE certificate in the public access versions of Oracle Java 6 (6u45) and Oracle Java 7 (7u80) is expired on the 20th April 2021. We still counter sign the jdk15to18 jars with this certificate for compatibility reasons, but Oracle does distribute JVMs for Java 6 and Java 7 with a newer, and stronger, certificate to holders of Java Support Contracts.

Others have contributed to this release, both with code and/or financially and you can find them listed in the contributors file. We would like to thank holders of Crypto Workshop support contracts for additional time that was contributed back to this release through left over consulting time provided as part of their support agreements. Thank you, one and all!

If you're interested in grabbing the lot in one hit (includes JCE, JCE provider, light weight API, J2ME, range of JDK compatibility classes, signed jars, fries, and king prawns...) download crypto-171.tar.gz or crypto-171.zip, otherwise if you are only interested in one version in particular, see below. Early access to our FIPS hardened version of the Java APIs is now available for both BC-FJA 1.0.3 and BC-FJA 2.0.0 as well, contact us at office@bouncycastle.org for further information.

Get the most out of your Bouncy Castle experience!

Get a support contract through Crypto Workshop. We have found two things that distinguish our support contract holders from our regular user base. Developers with access to a support contract are more likely to raise an issue with us early rather than try and muddle through, and developers with access to a support contract also take a more active interest in the beta releases, both FIPS and non-FIPS. The second one is useful as it means any issues or shortfalls in the beta are able to be fixed while the updates are still in beta. The first one is a real cost saver as it does not lead to us receiving emails starting with "Our development team has spent (some number of) weeks trying to work out..." It is much cheaper to have a support contract!

Signed JAR files

From release 1.40 some implementations of encryption algorithms were removed from the regular jar files at the request of a number of users. Jars with names of the form *-ext-* still include these (at the moment the list is: NTRU).

The following signed provider jars are provided so that you can make use of the debug information in them. In the case of the non-provider jars (bcpkix, bcpg, and bcmail), the jar files do not need to be signed to work. You can rebuild them with debug turned on, or operate directly from the source, if you need.
