NAME

sopv-inline-verify - Verify OpenPGP signed message

SYNOPSIS

sopv [ --debug ] inline-verify [ --not-before= DATE ] [ --not-after= DATE ] [ --verifications-out= VERIFICATIONS ] [ -- ] CERTS [ CERTS ...] <INLINESIGNED

DESCRIPTION

sopv inline-verify evaluates OpenPGP signatures bundled in a message. Its standard input can be either an OpenPGP Signed Message or a message signed with the OpenPGP Cleartext Signing Framework. If a valid signature is found, it returns 0 and emits the contents of the message (without any signatures) on standard output.

If no valid OpenPGP signature is found, sopv inline-verify returns non-zero.

EXAMPLES

if sopv inline-verify signer.cert < message.signed > message.txt; then
echo "The information found in message.txt was signed"
else
rm message.txt
echo "no valid signature found"
fi

OPTIONS

--not-before= DATE

Do not accept signatures made before the specified DATE . Supply DATE in ISO-8601 format, preferably in UTC (see DATE in sopv(1)).

--not-after= DATE

Do not accept signatures made after the specified DATE . Supply DATE in ISO-8601 format, preferably in UTC (see DATE in sopv(1)).

--verifications-out= VERIFICATIONS

If the caller wants to inspect the details of the valid signatures, it can use this argument to request those details. See VERIFICATIONS in sopv(1) for more details about this format.

ARGUMENTS

One or more CERTS arguments should point to OpenPGP certificates that would be acceptable signers.

RETURN CODE

sopv inline-verify returns 0 to indicate that at least one valid signature was found.

It may fail for other reasons, but NO_SIGNATURE (3) is a likely failure mode when the message contains no valid signature from any of the CERTS .
