Hi ,

Trying to use establish a connection using PKCS8 certificate created with
password.

*openssl pkcs8 -topk8 -inform PEM -in client.key -outform DER -out
client.pk8 -passout pass:foobar*

I set the properties as below:
*...*

*sslProperties.setProperty("sslkey",
"client.pk8");sslProperties.setProperty("sslpassword","foobar");*
*...*

*Connection connection = DriverManager.getConnection(jdbcUrl,
sslProperties);*
*....*
*This is failing with the error:*

*org.postgresql.util.PSQLException: SSL error: Connection reset at
org.postgresql.ssl.MakeSSL.convert(MakeSSL.java:43) at
