#110 Exported private key from 4096 bit SSH key is wrong

[Trel]

I did the following

1. Generated a key pair with ssh-keygen -b 4096 (no password)
2. Imported the key into XCA.
3. Exported the PEM Private key

The resulting Private key was NOT the same key I imported.
Further, when I tried to then import it into puttykeygen, it told me that file was not even a valid format.

I have some more information.

Export -> File -> PEM Private = Produces the same text as the original
Export -> Clipboard -> PEM Private = Produces something different

(This is on Windows if this makes a difference)

[Christian Hohnstaedt]

Export -> File -> PEM Private exports a PKCS#1 key
Export -> Clipboard -> PEM Private exports a PKCS#8 structure

puttykeygen apparently can't handle the PKCS#8 structure.

Fixed in XCA 1.4.1 with:

SF Bug #110 Exported private key from 4096 bit SSH key is wrong

Actually, it just differs. It is PKCS#8 instead of PKCS#1
