That "remembers" passphrase for the given key. $ KEYGRIP=$(gpg -fingerprint -fingerprint | grep fingerprint | tail -1 | cut -d= -f2 | sed -e 's/ //g') $ /usr/ local/opt/gpg-agent/libexec/gpg-preset-passphrase -preset $KEYGRIP Furthermore, the tool is not installed in your $PATH by default, but can be found at /usr/local/opt/gpg-agent/libexec/gpg-preset-passphrase when installed via Homebrew.įinally, you need a KEYGRIP, which this mailing list post informs us is actually the fingerprint of the key, and not just the fingerprint, but the subkey fingerprint, which you can display with the arcane gpg -fingerprint -fingerprint command. It is possible to increase that time span with the -default-cache-ttl and -max-cache-ttl settings, but if you want to make it permanent you need to use the gpg-preset-passphrase tool. This all works without the allow-preset-passphrase stuff, but the gpg-agent is configured to remember passphrases for only 600 seconds, unlike ssh-agent. (Which requires us to add allow-preset-passphrase in ~/.gnupg/nf. To make this work, we either need to do: $ eval $(gpg-agent -daemon -allow-preset-passphrase) Note the -use-agent switch which instructs gpg to try and use gpg-agent. Specifically, the kind of command I wanted to run was like: $ gpg -q -yes -batch -no-tty -use-agent -o $OUTFILE -d $INFILE For both versions, the user guide is the same, but the installation differs a bit.
#GPG TOOL FOR MAC PORTABLE#
WinGPG has two versions: a Windows-based setup and a portable version. Being a ‘shell’ for original GPG makes it your must-have protection tool. Decryptionĭecryption requires the private key, so to avoid entering a passphrase repeatedly, I wanted to use gpg-agent. Is GPG code secure enough WinGPG sure is. They can be restored (to "ultimate" trust) with: $ gpg -edit-key then entering trust at the prompt, entering and confirming the desired trust level ( 5) and then issuing a quit. I believe the cause is that my key pair was generated on another machine, and when I switched machines, it lost its trust settings. You may answer the next question with yes. Here the command I want to run is something like: $ gpg -a -q -batch -no-tty -yes -r -o $FILE.encrypted -e $FILEĮncryption is done with the public key, so you don’t need to enter a passphrase, but I was nevertheless getting derailed by a prompt: It is NOT certain that the key belongs to the person named The reason I started investigating this is so I could do batch encryption and decryption from a within a shell script.
#GPG TOOL FOR MAC INSTALL#
If you use Homebrew, it’s easy: $ brew install gpg-agentīut note, there is no man page ( here is one I found online), and for the gpg-preset-passphrase tool there is no man page I could find at all (other than this document).
