Since you are on Windows  make sure that your certificate in Windows  compatible   most importantly that it doesn t have  M in the end of each line  If you open it it will look like this   -----BEGIN CERTIFICATE----- M MIIDITCCAoqgAwIBAgIQL9 89q6RUm0PmqPfQDQ mjANBgkqhkiG9w0BAQUFADBM M   To solve  this  open it with Write or Notepad   and have it convert it to Windows  style  Try to run openssl x509 -text -inform DER -in server cert pem and see what the output is  it is unlikely that a private secret key would be untrusted  trust only is needed if you exported the key from a keystore  did you

My mistake was simply using the CSR file instead of the CERT file

Another possible cause of this is trying to use the  x509  module on something that is not X 509  The server certificate is X 509 format  but the private key is RSA  So  openssl rsa -noout -text -in privkey pem openssl x509 -noout -text -in servercert pem

Change encoding in notepad   UTF-8 with BOM  That is how it worked for me

My situation was a little different  The solution was to strip the  pem from everything outside of the CERTIFICATE and PRIVATE KEY sections and to invert the order which they appeared  After converting from pfx to pem file  the certificate looked like this   Bag Attributes localKeyID      issuer     -----BEGIN CERTIFICATE-----     -----END CERTIFICATE----- Bag Attributes more garbage    -----BEGIN PRIVATE KEY-----     -----END PRIVATE KEY-----   After correcting the file  it was just   -----BEGIN PRIVATE KEY-----     -----END PRIVATE KEY----- -----BEGIN CERTIFICATE-----     -----END CERTIFICATE-----

You can get this misleading error if you naively try to do this    clear  - gt  Private Key Encrypt - gt   encrypted  - gt  Public Key Decrypt - gt   clear    Encrypting data using a private key is not allowed by design    You can see from the command line options for open ssl that the only options to encrypt - gt  decrypt go in one direction public - gt  private     -encrypt        encrypt with public key   -decrypt        decrypt with private key   The other direction is intentionally prevented because public keys basically  can be guessed   So  encrypting with a private key means the only thing you gain is verifying the author has access to the private key   The private key encrypt - gt  public key decrypt direction is called  signing  to differentiate it from being a technique that can actually secure data     -sign           sign with private key   -verify         verify with public key   Note  my description is a simplification for clarity  Read this answer for more information

I had the same issue using Windows  got if fixed by opening it in Notepad   and changing the encoding from  UCS-2 LE BOM  to  UTF-8
