In version 3.0.0... setRequiredRole is the same setRequiredAuthority.... ?

I am setting
httpClientOptions.setSsl(true).setPemKeyCertOptions(new PemKeyCertOptions().setKeyPath(keyCrtFile).setCertPath(certCrtFile).setCertPath(caCrtFile));

as path and I have three certificate file which need to be authenticate ca.pem,cert.pem,key.pem
its giving me error
SEVERE: java.lang.RuntimeException: Missing -----BEGIN PRIVATE KEY----- delimiter

@kamaljeetrathi

You need to convert PKCS8 to PK8
openssl pkcs8 -topk8 -inform PEM -outform PEM -in ca.key -out ca-new.pem -nocrypt

Also, if using this code in Production, don't use 'SHA1WithRSA' as it is insecure and not even supported by Google Chrome any longer; use 'SHA256WithRSA' instead.
