Error - Encryption Command Failed Unusable Secret Key

Contents

[ date ] [ thread ] [ subject ] [ author ] Hello, I'm having another problem, again not in the FAQ: sql.gz: encryption failed: unusable public key This happens when I try to encrypt a file with my public key. gpg: skipped: unusable public key This is what I'm trying to do: I want to backup a remote database regularly gpg encryption failed no public key but I'd like to transmit it encrypted. So I want to run this command: sqldump ... | gzip -c | gpg ... -o gpg: [stdin]: encryption failed: no public key backup.gpg And then send the file backup.gpg to the client. This should be more than enogh for my needs. So, I have gpg installed in the server. I imported my public key and I didn't see any errors. there is no assurance this key belongs to the named user I went to the .gnupg directory and pubring.gpg is there and has a non-zero size. When I do a --list-keys on the server I see my public key there: /path/to/.gnupg/pubring.gpg -------------------------------------------------------- pub 1024D/42713DE9 2006-03-21 Daniel Carrera sub 2048g/F2EB9C97 2006-03-21 I am trying to encrypt with the following command: $ gpg -a --homedir /path/to/.gnupg -r daniel at theingots.org --batch -o sql.asc -e sql.gz Note: The '-e sql.gz' is for testing. I'll replace this

Gpg Batch Unusable Public Key

by a pipe later. When I run this command from a PHP script I get this error: gpg: F2EB9C97: There is no indication that this key really belongs to the owner gpg: sql.gz: encryption failed: unusable public key I don't care about the first line. I don't plan to have a secret key on the server. But that first line does show that it located the correct public key. I don't understand how the public key can be unusable if it can identify the key ID correctly. What are the chances of that? Could it be that I don't have a secret key? Why would a secret key be required if I just want to encrypt? Could it be because I'm running this from a PHP script? Why would that make the key unusable? I'm sure I'm not the first person who has thought of putting gpg on a server and using only a public key for encryption. Help? Any suggestions would be most appreciated.

The purpose of it to encrypt any important files like logs before admin pulling them into his local unusable public key using admin portal and then decrypt them using private key. The plan is to export public key into a file and make appliance installation process to import it using gpg --import command. But I realized, the key is needed to be trusted/signed before do any encryption. How to make this key is trusted without any human intervention at the time of installation? Btw, our appliance os is ubuntu vm and we use kickstart to automate.

One answer is you could sign the key. gpg --edit-key YOUR_RECIPIENT sign yes save The other is you could tell gpg to go ahead and trust. gpg --encrypt --recipient YOUR_RECIPIENT --trust-model always YOUR_FILE share|improve this answer answer

produces liberated ebooks for the true book lover. Creating the perfect GPG keypair March 13th, 2013 Before you start reading, keep in mind that I’m a layperson, just like you. This guide was created by synthesizing a lot of different information and tutorials available online, but I’m not a GPG developer, or even a cryptography professional. I'm just an enthusiast who thinks encryption is a critical part of modern society. The encryption technology landscape can change rapidly, the PGP standard is bewilderingly complex, and GPG is a stunningly obtuse piece of software on the best of days. There are a lot of ways of creating a functional keypair, and my perfect way may not be your perfect way. Please make sure to do your own research to ensure the explanations and steps below make sense for you and your situation. While I’ll do my best to keep this guide updated with what I personally consider to be the latest best practice, I can’t guarantee anything and I can’t answer any GPG-related questions. There’s a lot of information online on how to create a new GPG keypair. Unfortunately a lot of it is old advice and recommends settings that today might be unsafe. There also isn’t too much information on how to protect your keypair if you use a laptop that might get lost or stolen. Protecting your keypair on a laptop is tricky. On one hand, you need your private key with you to decrypt or sign messages. On the other hand, if your laptop is stolen then you risk losing your entire online identity, perhaps going back years, because the thief would have access to your private key and could then impersonate you. You’d think that today, where laptops and world travel are commonplace, there’d be a little more information on how to secure a private key you have to travel with. But I could only find one resource: the Debian Wiki entry on subkeys. Fortunately it turns out this wiki page has exactly the solution we need. Subkeys help protect your identity in case of private key (laptop) theft If a thief gets ahold of the laptop with your private key on it, it’s pretty much game over. The thief can not only decrypt messages intended for you, they can also impersonate you by signing messages with your private key. Your only recourse would be to revoke your key, but that would mean losing years of signatures o
