Subject [ANNOUNCEMENT] Apache Commons Crypto 1.0.0 Released
Date Tue, 09 Aug 2016 08:45:31 GMT
The Apache Commons Crypto team is pleased to announce the release of Apache Commons Crypto
1.0.0, The release is available for download at

Apache Commons Crypto is a cryptographic library optimized with AES-NI (Advanced Encryption
Standard New Instructions). It provides Java API for both cipher level and Java stream level.
Developers can use it to implement high performance AES encryption/decryption with the minimum
code and effort. Please note that Crypto doesn't implement the cryptographic algorithm such
as AES directly. It wraps to Openssl or JCE which implement the algorithms.



1. Cipher API for low level cryptographic operations.

2. Java stream API (CryptoInputStream/CryptoOutputStream) for high level stream encryption/decryption.

3. Both optimized with high performance AES encryption/decryption. (1400 MB/s - 1700 MB/s
throughput in modern Xeon processors).

4. JNI-based implementation to achieve comparable performance to the native C/C++ version
based on OpenSSL.

5. Portable across various operating systems (currently only Linux/MacOSX/Windows);

Apache Commons Crypto loads the library according to your machine environment (it checks system
properties, `` and `os.arch`).

6. Simple usage. Add the commons-crypto-(version).jar file to your classpath.

Export restrictions


This distribution includes cryptographic software. The country in which you currently reside
may have restrictions on the import, possession, use, and/or re-export to another country,
of encryption software. BEFORE using any encryption software, please check your country's
laws, regulations and policies concerning the import, possession, or use, and re-export of
encryption software, to see if this is permitted. See <> for
more information.

The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has classified
this software as Export Commodity Control Number (ECCN) 5D002.C.1, which includes information
security software using or performing cryptographic functions with asymmetric algorithms.
The form and manner of this Apache Software Foundation distribution makes it eligible for
export under the License Exception ENC Technology Software Unrestricted (TSU) exception (see
the BIS Export Administration Regulations, Section 740.13) for both object code and source

The following provides more details on the included cryptographic software:

* Commons Crypto use [Java Cryptography Extension](
provided by Java

* Commons Crypto link to and use [OpenSSL]( ciphers

Initial release


The initial release is known to build on Linux, MacOS/X and Windows (using MinGW).

It may build on other systems.

Please note that the JNA interface to OpenSSL is a preliminary release.

It is relatively slow, but may be of use on systems which aren't yet supported by the JNI

See the release-notes at

for a full list of changes.

Please verify signatures using the KEYS file available at the above location when downloading
the release.
