```
public class DockerKeyIdentifier
extends Object
```
The “kid” field has to be in a libtrust fingerprint compatible format. Such a format can be generated by following steps: 1) Take the DER encoded public key which the JWT token was signed against. 2) Create a SHA256 hash out of it and truncate to 240bits. 3) Split the result into 12 base32 encoded groups with : as delimiter. Ex: "kid": "PYYO:TEWU:V7JH:26JV:AQTZ:LJC3:SXVJ:XGHA:34F2:2LAQ:ZRMK:Z7Q6"
