+## Prerequisites
+
+* Pulsar Java/Python/C++/Node.js client 2.7.1 or later versions.
+* Pulsar Go client 0.6.0 or later versions.
+
+## Configure end-to-end encryption
+
+1. Create both public and private key pairs.
+   * ECDSA（for Java and Go clients)
+     ```shell
+     openssl ecparam -name secp521r1 -genkey -param_enc explicit -out test_ecdsa_privkey.pem
+     openssl ec -in test_ecdsa_privkey.pem -pubout -outform pem -out test_ecdsa_pubkey.pem
+     ```
+
+   * RSA (for Python, C++ and Node.js clients)
+     ```shell
+     openssl genrsa -out test_rsa_privkey.pem 2048
