gpgv
Simplified OpenPGP signature verifier
TLDR
Verify a signed file
$ gpgv [file.sig]
Verify detached signature$ gpgv [file.sig] [file]
Use specific keyring$ gpgv --keyring [keyring.gpg] [file.sig]
Verbose verification$ gpgv -v [file.sig]
Quiet mode$ gpgv -q [file.sig]
SYNOPSIS
gpgv [options] [sigfile] [files]
DESCRIPTION
gpgv is a stripped-down version of gpg designed solely for verifying OpenPGP signatures. It assumes all keys in the keyring are trustworthy and does not check for expired or revoked keys.By default, it uses the trustedkeys.kbx or trustedkeys.gpg keyring in the GnuPG home directory. It is commonly used in package managers and automated verification scripts where trust is pre-established.
PARAMETERS
-v, --verbose
More information during processing.-q, --quiet
Try to be as quiet as possible.--keyring file
Use specified keyring.--homedir dir
GnuPG home directory.--ignore-time-conflict
Turn timestamp checks into warnings.--weak-digest name
Treat digest as weak.--status-fd n
Write status strings to file descriptor.
INSTALL
sudo apt install gpgv
sudo apk add gpgv
CAVEATS
Returns 0 if verification succeeds, 1 if any signature is bad, and other codes for fatal errors. Unlike gpg, gpgv does not validate key trust.
