generate the thumbprint for a key
SYNOPSIS
jose thumbprint [-s SHASIZE | --sha SHASIZE] [-U --update [-b --beautify -p --private]] [-k|--key] [JWKSTRING]
Prints the thumbprint for the provided JWKSTRING and SHASIZE.
If no key is provided, then thumbprint reads the key from STDIN.
The SHASIZE can be either 1, 256, 384, or 512. Default SHASIZE is 256.
If -U or --update is present, then the tool will update the key id
to the new thumbprint and return the updated key. In this case the -b
or --beautify option will beautify the key for readability, and the tool
accepts the -p or --private option. If this option is not present,
then the key will only contain the public components. In order to get all key
components of the initial key passing -p or --private is
useful. This option has no effect if the initial key was a public key.
