After converting a .cert certification extension to a .jks, the Stat web client we get a warning message that the certificate is not trusted by a CA.
原因
The .cert certification is not signed by a third party certification authority.
解决办法
Instead of exporting the certificate with a .cert extension, it is best to export the certificate with a .pfx extension and then convert this extension to a .jks extension in which Stat can use.
