jose-jwk-thp - Calculates the JWK thumbprint

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

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

• -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

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
