WELCOME

Welcome to the home of the Legion of the Bouncy Castle. A fun place to stay, if
you've got some time to kill.



Here at the Bouncy Castle, we believe in encryption. That's something that's
near and dear to our hearts. We believe so strongly in encryption, that we've
gone to the effort to provide some for everybody, and we've now been doing it
for over 20 years!

The Bouncy Castle Crypto APIs are looked after by an Australian Charity, the
Legion of the Bouncy Castle Inc., which looks after the care and feeding of the
Bouncy Castle APIs. Help us keep this effort Free, Open Source, and Maintained!
Please see our donations page or purchase a support contract through Keyfactor.
Requests to sponsor specific work on the APIs are also most welcome.

The Bouncy Castle APIs currently consist of the following:

 * A lightweight cryptography API for Java and C#.

 * A provider for the Java Cryptography Extension (JCE) and the Java
   Cryptography Architecture (JCA).

 * A provider for the Java Secure Socket Extension (JSSE).

 * A clean room implementation of the JCE 1.2.1.

 * A library for reading and writing encoded ASN.1 objects.

 * Lightweight APIs for TLS (RFC 2246, RFC 4346) and DTLS (RFC 6347/ RFC 4347).

 * Generators for Version 1 and Version 3 X.509 certificates, Version 2 CRLs,
   and PKCS12 files.

 * Generators for Version 2 X.509 attribute certificates.

 * Generators/Processors for S/MIME and CMS (PKCS7/RFC 3852).

 * Generators/Processors for OCSP (RFC 2560).

 * Generators/Processors for TSP (RFC 3161 & RFC 5544).

 * Generators/Processors for CMP and CRMF (RFC 4210 & RFC 4211).

 * Generators/Processors for OpenPGP (RFC 4880).

 * Generators/Processors for Extended Access Control (EAC).

 * Generators/Processors for Data Validation and Certification Server (DVCS) -
   RFC 3029.

 * Generators/Processors for DNS-based Authentication of Named Entities (DANE).

 * Generators/Processors for RFC 7030 Enrollment over Secure Transport (EST).

 * A signed jar version suitable for JDK 1.4-1.15 and the Sun JCE.

The lightweight API works with everything from the J2ME to the JDK 1.15 and
there is also an API in C# providing equivalent functionality for most of the
above.

For further details have a look in either our Java project pages or our C#
project pages where you can find downloads, mailing lists, and other resources.

If you want to provide feedback directly to the members of The Legion or report
something you believe to be a security issue then please use
feedback-crypto@bouncycastle.org. We can provide a PGP key if required.

If you need a support agreement or have issues with the Bouncy Castle APIs that
may require consulting, mentoring, or education, please contact us at Crypto
Workshop

JAVA RELEASE 1.77 IS NOW AVAILABLE FOR DOWNLOAD.

TUESDAY 13TH NOVEMBER 2023

Primarily this release updates the NIST PQC finalists to the drafts published as
FIPS PUB 203, 204, and 205. Some issues in DTLS have also been fixed and some
additional control properties have been added to the BCJSSE. Support has also
been added for PKCS#10 requests with altSignature/altPublicKey extensions and
for DeltaCertificate requests. A final note: the TLS/JSSE APIs now disable RSA
encryption based cipher-suites by default.

For more details go to our latest releases page to download the new version and
see the release notes


JAVA FIPS RELEASE 1.0.2.4 IS NOW AVAILABLE FOR DOWNLOAD.

THURSDAY 28TH SEPTEMBER 2023

A performance/utility patch to our fourth Java FIPS release, certified for Java
1.7, Java 1.8, Java 11, and Java 17 is now available at our Java FIPS page.. In
addition to being certified for 1.7/1.8/11/17 the jar is also compatible with
Java 1.5 and Java 1.6.


JAVA RELEASE 1.76 IS NOW AVAILABLE FOR DOWNLOAD.

SATURDAY 29TH JULY 2023

1.76 is a mixed release. The main changes are around DTLS/TLS and include
support for a "jdk.tls.client.useCompatibilityMode" property, DTLS server
support for client_certificate_type, and a fix for a regression causing null
pointer exceptions on negotiating TLSv1.1 or earlier sessions. In addition, a
bug in the high level Cipher.unwrap() method for HQC has been fixed, SPHINCS+
simple parameters are now fully supported by the BCPQC provider, and Kyber plus
the Round 4 KEMs are now supported by the CRMF/CMS/CMP APIs. Further work has
been done on updating the PGP APIs in line with the upcoming revision to the
standard.

For more details go to our latest releases page to download the new version and
see the release notes


JAVA RELEASE 1.75 IS NOW AVAILABLE FOR DOWNLOAD.

WEDNESDAY 21ST JUNE 2023

1.75 is a minor release. Unfortunately some Java 8 usages managed to "sneak"
into the Java 5 to Java 8 jars making them less than ideal for anything other
than Java 8. The 1.75 release fixes that and also a TLS issue and removes some
deprecated methods and dead classes from the core ASN.1 library.

For more details go to our latest releases page to download the new version and
see the release notes


JAVA LTS 2.73.0 IS NOW AVAILABLE FOR DOWNLOAD.

WEDNESDAY 24TH MAY 2023

Our first LTS release for Java. Designed for as a long term stable release based
on BC Java 1.73, the release also features JNI support for Intel hardware.
Download it now from the Java LTS Page.


C# RELEASE 2.2.1 IS NOW AVAILABLE FOR DOWNLOAD.

FRIDAY 21ST APRIL 2023

Due to a build error 2.2.0 was not optimised, this updated build fixes the issue
as well as fixing a gap in the RFC 9146 connection ID in DTLS support and a
regression in GcmBlockCipher which reduced the number of blocks it could
encrypto (~2^31 blocks instead of ~2^32).

Please see the release notes for further details.


C# RELEASE 2.2.0 IS NOW AVAILABLE FOR DOWNLOAD.

MONDAY 17TH APRIL 2023

This release features support for X.509 Section 9.8 alt signatures and public
keys, rethrow syntax has been improved which should ease debugging, RFC 9146
connection ID in DTLS has been added, support has been added for OpenSSH public
and private key formats as well as fixes for some reported issues.

Please see the release notes for further details.


JAVA RELEASE 1.73 IS NOW AVAILABLE FOR DOWNLOAD.

SATURDAY 8TH APRIL 2023

This release is both targeting features and security. Review of the PQC work has
been done and significant issues found have been addressed in the
implementations. Several candidate algorithms from the NIST lightweight
cryptography competition have been added including the finalist Ascon.
Performance has been improved in existing PQC implementations, EdDSA, PEM
parsing, and CRC24 and implementations of Blake2bp, Blake2sp, and HPKE (RFC
9180) have been added to the light-weight APIs.
