(SSL)windows secure Channel doesn't allow pemkeyfile has password

if I compile the c driver with -DENABLE_SSL=WINDOWS (windows secure Channel), connection would be failed if the client pem key file has password.

the error info of log:

[error@stream-secure-channel] Failed to parse private key. ASN1 bad tag value me t. (0x8009310B) [warning@stream-secure-channel] a client certificate has been requested

---

note:

1. I create the private key for the pem file with this command: openssl genrsa -des3 -out server.key 2048 , and then input password : 1234

   using mongo.exe , I can connect with the same pem file and password from my own working computer successfully: mongo --host 10.154.10.39 --ssl --authenticationDatabase admin --username user1 -p 123 --sslCAFile d:/ca.pem --sslPEMKeyFile d:/cry.pem --sslPEMKeyPassword 1234

   however, if my program uses the mongocxx driver, always get failed.

2. if I use the driver which is compiled with "-DENABLE_SSL=OPENSSL", this issue dissapears.
