.TH "JOSE\-JWS\-VER" "1" "May 2017" "" ""
.
.SH "NAME"
\fBjose\-jws\-ver\fR \- Verifies a JWS using the supplied JWKs
.
.SH "SYNOPSIS"
\fBjose jws ver\fR \-i JWS [\-I PAY] \-k JWK [\-a] [\-O PAY]
.
.SH "OVERVIEW"
The \fBjose jws ver\fR command verifies a signature over a payload using one or more JWKs\. When specifying more than one JWK (\fB\-k\fR), the program will succeed when any of the provided JWKs successfully verify a signature\. Alternatively, if the \fB\-a\fR option is given, the program will succeed only when all JWKs successfully verify a signature\.
.
.P
If the JWS is a detached JWS, meaning that the payload is stored in binary form external to the JWS itself, the payload can be loaded using the \fB\-I\fR parameter\.
.
.P
Please note that, when specifying the \fB\-O\fR option to output the payload, the payload is output whether or not the signature validates\. Therefore, you must check the return value of the command before trusting the data\.
.
.SH "OPTIONS"
.
.TP
\fB\-i\fR \fIJSON\fR, \fB\-\-input\fR=\fIJSON\fR
