== NAME

jose-jwk-thp - Calculates the JWK thumbprint

== SYNOPSIS

*jose jwk thp* -i JWK [-H ALG] [-o THP]

== OVERVIEW

The *jose jwk thp* command calculates the thumbprint of one or more JWKs.

== OPTIONS

* *-i* _JSON_, *--input*=_JSON_ :
  Parse JWK(Set) from JSON

* *-i* _FILE_, *--input*=_FILE_ :
  Read JWK(Set) from FILE

* *-i* -, *--input*=- :
  Read JWK(Set) standard input

* *-a* _ALG_, *--algorithm*=_ALG_ :
  Use the specified hash algorithm (case sensitive)

* *-a* ?, *--algorithm*=? :
  List available hash algorithms

* *-o* _FILE_, *--output*=_FILE_ :
  Write thumbprint(s) to FILE

* *-o* -, *--output*=- :
  Write thumbprint(s) to standard input

* *-f* _THP_, *--find*=_THP_ :
  Search input keys for JWK with the given thumbprint

== EXAMPLES

Calculate the S1 thumbprint of a newly generated key:

    $ jose jwk gen -i '{"alg":"ES256"}' -a S1 | jose jwk thp -i-
    BzmSH6W8a8LlbQ1mD0iBJdYj4x4

Calculate the S256 thumbprints of a JWKSet containing two keys:

    $ jose jwk thp -i keys.jwkset -a S256

    jo_j_O5gqYpKcZKHPp3miTszAeV60MXHvdb_kkjjTWE

Find the input key with the given thumbprint:

    $ jose jwk thp -i keys.jwkset -f HYRNOxxOOHap0amTONoy1bHnS5M -o key.jwk
