I've tried converting a PEM-encoded key to DER format, and it appears the password is stripped regardless of the -passout argument.
Example:
openssl rsa -in tmp.pem -outform DER -out tmp.der -passin pass:foo -passout pass:bar -des3
The resulting key appears no longer password-protected, so I am assuming that DER format does not support a password - is that correct?
What alternative way is there to store this in a compact, binary form, and keep the password-protection?
