this is how i'm trying to connect

jdbc:postgresql://hostname:5432/dbname?sslmode=require&sslcert=D:\\work\\linux\\postgres-ssl\\postgresql.crt&sslkey=D:\\work\\linux\\postgres-ssl\\postgresql.pk8&sslrootcert=D:\\work\\linux\\postgres-ssl\\root.crt&sslpassword=password";`

i'm on springboot version 2.5.4 with Java 11. i created the certificates using openssl utility

UPDATE:

i created the key using openssl pkcs8 -topk8 -v1 PBE-SHA1-3DES -inform PEM -outform DER -in postgresql.key -out postgresql.pk8 and now the exception is different
