Latest Java Releases
Release 1.54 is now available for download.This is primarily a security release concerning (D)TLS 1.2. Motivated by CVE-2015-7575, we have added validation that the signature algorithm received in DigitallySigned structures is actually one of those offered (in signature_algorithms extension or CertificateRequest). With our default TLS configuration, we do not believe there is an exploitable vulnerability in any earlier releases. Users that are customizing the signature_algorithms extension, or running a server supporting client authentication, are advised to double-check that they are not offering any signature algorithms involving MD5.
In terms of new features, the CMS API now supports the PKCS#7 ANY type for encapsulated content, RFC 3370, Camellia, and SEED are now supported for key agreement in CMS, and CTR/SIC modes now provide an explicit internal counter if initialised with a short IV. TLS/DTLS now includes a non-blocking API. The Blake2b digests are now actually supported in the provider (sorry, it got missed in 1.53...) and ClassCastException issues with Cipher.getOutputSize() for IES ciphers have been fixed. Finally, in accordance with advice from the algorithm's authors, Serpent has been modified to conform to the NESSIE vector suite, the previous version of Serpent, which conforms to the NIST submission format, is now called Tnepres.
Further details on other additions and bug fixes can be found in the release notes file accompanying the release.
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).
Others have contributed to this release, both with code and/or financially. You can find them listed in the contributors file. We would also 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-154.tar.gz or crypto-154.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 as well, contact us at email@example.com for further information.
Keeping the Bouncy Castle Project Going
With various algorithm changes, updates, security issues in protocols, and having to write vendor statements for organisations like CERT, keeping the Bouncy Castle project going is turning into a full time job and several of us have now given up permanent work in order to free up time to work on it. If you are making use of our software, and are interested in making sure we are always here when you need us, there are two principal ways you can help.
The first is by getting a support contract or by sponsoring specific work on the project. Not only will you get a hot-line to Bouncy Castle developers, consulting time, and release alerts if you need them, but you also join our FIPS early access program. You can find out further information on support contracts and consulting at Crypto Workshop.
Secondly, the Bouncy Castle APIs are formally owned by a registered Australian Charity, the Legion of the Bouncy Castle Inc, ABN 84 166 338 567. Without considering the costs of actually doing what we do from release to release, we're also funding certifications, such as FIPS, for the APIs. We can accept donations via PayPal, Bitcoin, or direct transfer. If this sounds more like you, and you want to see this project continue to prosper, please visit our donations page to help. Thanks!
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).
|Provider||Clean room JCE|
|JDK 1.5 - JDK 1.8||bcprov-jdk15on-154.jar
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.
|Providers with debug|
|JDK 1.5 - JDK 1.8||bcprov-debug-jdk15on-154.jar||bcprov-ext-debug-jdk15on-154.jar|

Too slow? You can also find the latest versions on one of our mirrors:
The current working betas, when available, for the next release for JDK 1.3 to JDK 1.8 can be found at http://www.bouncycastle.org/betas. If you need a beta to be made available for another version of Java please ask by emailing firstname.lastname@example.org.
The BC jars are now mirrored on the Maven central repository. You can find them at http://repo2.maven.org/maven2/org/bouncycastle.
Just want to look at the source? The source code repository is now mirrored on GitHub and accessible from here. The repository can be cloned using either
git clone https://github.com/bcgit/bc-java.gitor git protocol
git clone git://github.com/bcgit/bc-java.git
Previous releases, as well as the latest ones, can be downloaded from our ftp server ftp.bouncycastle.org. Please note the FTP server does not support passive mode.
