Hi All,
Shall we use Nimbus libraryto generate JWT in API Manager?
Currently, we are generating the token without any standard libraries which
leads to errors like [2] and [3].
For the JIRA [3], currently we are having following code snippet to
create x5t header.
byte[] digestInBytes = digestValue.digest();
String publicCertThumbprint = hexify(digestInBytes);
String base64EncodedThumbPrint = Base64Utils.encode(
publicCertThumbprint.getBytes());
But, We have to use in the following way inorder to fix by ourself
byte[] digestInBytes = digestValue.digest();
String base64EncodedThumbPrint;
base64EncodedThumbPrint = Base64Utils.encode(digestInBytes);
base64EncodedThumbPrint = base64EncodedThumbPrint.split("=")[0]; // Remove
any trailing '='s
base64EncodedThumbPrint = base64EncodedThumbPrint.replace('+', '-'); //
62nd char of encoding
base64EncodedThumbPrint = base64EncodedThumbPrint.replace('/', '_'); //
63rd char of encoding
return base64EncodedThumbPrint;
If we are using Nimbus, we can use JWSHeader.Builder [4] to generate JWT
Headers like
JWSHeader header = new JWSHeader.Builder(JWSAlgorithm.HS256).
contentType("text/plain").
customParam("exp", new Date().getTime()).
build();
We can add custom headers too. Appriciate your input on this.
