I am confused why I get this message:
gpg: decryption failed: No secret key
I tried gpg --import but still doesn't help.
John-Wong:~ jwong$ gpg --import mastersub.key

Doesn't »--passphrase-file« need an argument, does it? If so,
gpg looks for a passphrase file named »-o«.

This is "encrypting" the symmetric key sk to the public key. It is equal to what
PKCS#1 would consider the signature primitive RSASP1, mathematically equivalent
to the decryption primitive RSADP.

Hi Dirk & Ken,
I'm working on a similar problem... automated decryption "in the field" and
what I have come to is this:
Encrypt the message with a symmetric algorithm, adding salt and a
hash/checksum to ensure validity. Then,

Let me clarify because it is not obvious: this is not the case. It is
perfectly valid to have a secret key without a passphrase. The drawback
is anyone with file access to the on-disk copy of the secret key has
full po

For this usecase I'm using AgentForwarding ( https://wiki.gnupg.org/

h into the remote machine to
trigger decryption and passphrase entry.
B) You can secure the private key on the remote machine by using a
Secure Element. OpenPGP Card, Yubikey..
Since the key resides only on the Secure Element and can not be
exported it is save from virtual theft - obvious
Hi,
The situation is that there is a machine on remote. And I want to send an
encrypted file to that remote machine and let the machine decrypt the file
automatically. So I'm facing the problem that:
* To encrypt the file by a public key:
Which means I have to put a secret key on the remot

Obviously I meant key stretching.
