.
.SH "NAME"
\fBjose\-jwk\-use\fR \- Validates a key for the specified use(s)
.
.SH "SYNOPSIS"
\fBjose jwk use\fR \-i JWK [\-a] [\-r] \-u OP
.
.SH "OVERVIEW"
The \fBjose jwk use\fR command validates one or more JWK(Set) inputs for a given set of usages\. This will be validated against the "use" and "key_ops" properties of each JWK\.
.
.P
By default, if a JWK has no restrictions an operation will be allowed\. However, by specifying the \fB\-r\fR option you can ensure that a JWK will not be allowed unless it explicitly permits the option\.
.
.P
In normal operation, \fBjose jwk use\fR will fail if any of the JWKs do not validate\. However, if the \fB\-o\fR option is used \fBjose jwk use\fR will instead write a JWK(Set) containing all of the input keys that validate\. If no JWKs validate, the command will fail\.
