JOSE-JWS-SIG(1) JOSE-JWS-SIG(1) NAME jose-jws-sig - Signs a payload using one or more JWKs SYNOPSIS jose jws sig [-i JWS] [-I PAY] [-s SIG] -k JWK [-o JWS] [-O PAY] [-c] OVERVIEW The jose jws sig command signs a payload using one or more JWKs. The pay- load can be provided either in its decoded form (-I) or embedded in an ex- isting JWS (-i). A detached JWS can be created by specifying the -O option. In this case, the decoded payload will be written to the output specified and will not be included in the JWS. If only one key is used (-k), the resulting JWS may be output in JWS Com- pact Serialization by using the -c option. This command uses a template based approach for constructing a JWS. You can specify templates of the JWS itself (-i) or for the JWS Signature Object (-r). Attributes specified in either of these templates will appear unmodi- fied in the output. One exception to this rule is that the JWS Protected Header should be specified in its decoded form in the JWS Signature Object template. This command will automatically encode it as part of the encryp- tion process. If you specify a JOSE Header Parameter (via either the -i or -r options) that affects the construction of the JWE, this command will attempt to be- have according to this parameter as if it were configuration. Currently, jose will modify its behavior for the "alg" JOSE Header Parameter (see RFC 7515 Section 4.1.1). However, it is not necessary to provide any templates: jose jwe enc will automatically fill in the "alg" parameter by inferring the correct algo- rithm from the provided input JWKs. Therefore, the -i and -r options should generally be used for providing extended JWE metadata. It is possible to specify an existing JWS as the JWS template input (-i). This allows the addition of new signatures to an existing JWS.
