+Configuration of Certificates in test environment(For FTP over TLS):
+====================================================================
+DFC supports two protocols: FTPES and SFTP.
+For FTPES, it is mutual authentication with certificates.
+In our test environment, we use vsftpd to simulate xNF, and we generate self-signed
+keys & certificates on both vsftpd server and DFC.
+1. generate key & certificate with openssl for DFC：
+    openssl genrsa -out dfc.key 2048
+    openssl req -new -out dfc.csr -key dfc.key
+    openssl x509 -req -days 365 -in dfc.csr -signkey dfc.key -out dfc.crt
+2. generate key & certificate with openssl for vsftpd:
+    openssl genrsa -out ftp.key 2048
+    openssl req -new -out ftp.csr -key ftp.key
+    openssl x509 -req -days 365 -in ftp.csr -signkey ftp.key -out ftp.crt
+3. configure java keystore in DFC:
+    We have two keystore files, one for TrustManager, one for KeyManager.
+    First, create a jks keystore for TrustManager:
+      keytool -keystore ftp.jks -genkey -alias ftp
+    Second, convert your certificate in a DER format :
+      openssl x509 -outform der -in ftp.crt -out ftp.der
+    And after, import it in the keystore :
+      keytool -import -alias ftp -keystore ftp.jks -file ftp.der
+
+    For KeyManager:
+    First, create a jks keystore:
+      keytool -keystore dfc.jks -genkey -alias dfc
+    Second, import dfc.crt and dfc.key to dfc.jks. This is a bit troublesome.
+      Step one: Convert x509 Cert and Key to a pkcs12 file
+      openssl pkcs12 -export -in dfc.crt -inkey dfc.key \
+               -out dfc.p12 -name [some-alias] \
+      Note: Make sure you put a password on the p12 file - otherwise you'll get
+      a null reference exception when you try to import it. (In case anyone else had this headache).
+      Note 2: You might want to add the -chainoption to preserve the full certificate chain.
+      Step two: Convert the pkcs12 file to a java keystore
+      keytool -importkeystore \
+        -deststorepass [changeit] -destkeypass [changeit] -destkeystore dfc.jks \
+        -srckeystore dfc.p12 -srcstoretype PKCS12 -srcstorepass some-password \
+        -alias [some-alias]
+    Finished
+
+4. configure vsftpd:
+    update /etc/vsftpd/vsftpd.conf:
+      rsa_cert_file=/etc/ssl/private/ftp.crt
+      rsa_private_key_file=/etc/ssl/private/ftp.key
+      ssl_enable=YES
+      allow_anon_ssl=NO
+      force_local_data_ssl=YES
+      force_local_logins_ssl=YES
+
+      ssl_tlsv1=YES
+      ssl_sslv2=YES
+      ssl_sslv3=YES
+
+      require_ssl_reuse=NO
+      ssl_ciphers=HIGH
+
+      require_cert=YES
+      ssl_request_cert=YES
+      ca_certs_file=/home/vsftpd/myuser/dfc.crt
+
+5. configure config/datafile_endpoints.json:
+   Update the file accordingly:
+            "ftpesConfiguration": {
+                "keyCert": "/config/dfc.jks",
+                "keyPassword": "[yourpassword]",
+                "trustedCA": "/config/ftp.jks",
+                "trustedCAPassword": "[yourpassword]"
+            }
+6. This has been tested with vsftpd and dfc, with self-signed certificates.
+   In real deployment, we should use ONAP-CA signed certificate for DFC, and vendor-CA signed
+   certificate for xNF.
