NAME

6       sq-verify - Verifies signed messages or detached signatures
7
8       When verifying signed messages, the message is written to stdout or the
9       file given to --output.
10
11       When a detached message is verified, no output is  produced.   Detached
12       signatures are often used to sign software packages.
13
14       Verification  is  only successful if there is no bad signature, and the
15       number of successfully verified signatures reaches the  threshold  con‐
16       figured  with the "--signatures" parameter.  If the verification fails,
17       the program terminates with an exit status indicating failure.  In  ad‐
18       dition  to  that,  the last 25 MiB of the message are withheld, i.e. if
19       the message is smaller than 25 MiB, no output is produced, and if it is
20       larger, then the output will be truncated.
21
22       The converse operation is "sq sign".

SYNOPSIS

26       sq verify [FLAGS] [OPTIONS] [--] [FILE]
27

FLAGS

29       -h, --help
30              Prints help information
31

OPTIONS

33       -o, --output FILE
34              Writes to FILE or stdout if omitted
35
36
37       --detached SIG
38              Verifies a detached signature
39
40
41       -n, --signatures N
42              Sets  the  threshold of valid signatures to N. If this threshold
43              is not reached, the message will  not  be  considered  verified.
44              [default: 1]

46
47       --signer-cert CERT
48              Verifies signatures with CERT

ARGS

51       FILE   Reads from FILE or stdin if omitted
