In an opened KeyStore window, select the key pair entry and click on
the right mouse button - if the private key is not unlocked you will be
prompted for the private key password. From the popup menu select
Export > Export Private
Key action. The exported Private Key type can be PKCS #8
(both binary and PEM) or OpenSSL - this is selectable from the right side
of the file chooser window. The exported key can also be encrypted (in
this case an encryption algorithm and a password must be provided) or not.
For PKCS #8 one can further chose to PEM encode the file, by using the
File Chooser filter (Files of type: PKCS #8 Private Key Files (PEM
The Private Key will be exported in the selected file, having the following formats, depending on the export Private Key Type and file chooser filter selection:
PKCS #8 Private Key Files;
PKCS #8 Private Key Files (PEM encoded);
OpenSSL Private Key Files (PEM encoded).
The encryption algorithm is dependent on the selected export Private Key Type and CERTivity automatically changes this in the list.
