QIE can accept an expired certificate if it is in a Java truststore and specified on the FTP connection.
1. Download the FTPS certifcate
Us FireFTP add-on for FireFox which enables FTPS protocol and stores certificate in FireFox default store. Install add-on and just type in address bar ftps://your.site and connect. Then export the certificate from tools->options->advanced->encryption->vew certs.
OpenSSL has a command line you can use to get the certificate
openssl s_client -showcerts -connect ftp.site.com:990
2. Create a Java truststore
1. Import the .cer file into qie under the certificates.
2. Export the certificate as a Java Key Store and set a password.
3. Save the .jks file in a location that QIE can access on the qie server. Example: C:\programdata\qie\SSL
3. Add the Custom Camel Parameter.
ftpClient.trustStore.file = C:\programdata\qie\SSL\javatruststore.jks
ftpClient.trustStore.type = JKS
ftpClient.trustStore.algorithm = SunX509
ftpClient.trustStore.password = jksPassword
