+## Cryptographic Software Notice
+
+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 http://www.wassenaar.org for
+more information.
+
+The Apache Software Foundation has classified this software as Export
+Commodity Control Number (ECCN) 5D002, 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
+"publicly available" Section 742.15(b) exemption (see the BIS Export
+Administration Regulations, Section 742.15(b)) for both object code
+and source code.
+
+The following provides more details on the included cryptographic
+software:
+
+ * Apache Flink Shaded publishes flink-shaded-netty-tcnative-dynamic
+ (linking against a system-provided OpenSSL) and
+ flink-shaded-netty-tcnative-static (embedding Google's BoringSSL
+ library) as convenience binaries on Maven Central, for use as
+ Apache Flink's optional OpenSSL-based SSL engine. The source
+ release contains build scripts only; the cryptographic libraries
+ are included in the compiled artifacts.
