Thanks Harshan,
But I am using multitenancy feature of API manager so the token is
encrypted using using domainname.jks not wso2carbon.jks.
And the domainname.jks does not exists in the physical directory.
My requirement is to validate the jwt token signature generated by wso2 for
tenant using the public key in the client side.
eg,
I have a tenant say ibm.com, the code in AbstractJWTToken is signing the
token using a key which does not exists, is that a in-memory key in the
class AbstractJWTGenerator.
private byte[] signJWT(String assertion, String endUserName)
throws APIManagementException {
try {
//get tenant domain
String tenantDomain =
MultitenantUtils.getTenantDomain(endUserName);
//get tenantId
int tenantId = APIUtil.getTenantId(endUserName);
Key privateKey = null;
if (!(privateKeys.containsKey(tenantId))) {
APIUtil.loadTenantRegistry(tenantId);
//get tenant's key store manager
KeyStoreManager tenantKSM =
KeyStoreManager.getInstance(tenantId);
if
(!tenantDomain.equals(MultitenantConstants.SUPER_TENANT_DOMAIN_NAME)) {
//derive key store name
String ksName = tenantDomain.trim().replace(".", "-");
String jksName = ksName + ".jks";
//obtain private key
//TODO: maintain a hash map with tenants' private keys
after first initialization
privateKey = tenantKSM.getPrivateKey(jksName,
tenantDomain);
} else {
try {
privateKey = tenantKSM.getDefaultPrivateKey();
} catch (Exception e) {
log.error("Error while obtaining private key for
super tenant", e);
}
}
if (privateKey != null) {
privateKeys.put(tenantId, privateKey);
}
} else {
privateKey = privateKeys.get(tenantId);
}
//initialize signature with private key and algorithm
Signature signature = Signature.getInstance(signatureAlgorithm);
signature.initSign((PrivateKey) privateKey);
//update signature with data to be signed
byte[] dataInBytes = assertion.getBytes();
signature.update(dataInBytes);
//sign the assertion and return the signature
byte[] signedInfo = signature.sign();
return signedInfo;
} catch (NoSuchAlgorithmException e) {
String error = "Signature algorithm not found.";
//do not log
throw new APIManagementException(error);
} catch (InvalidKeyException e) {
String error = "Invalid private key provided for the signature";
//do not log
throw new APIManagementException(error);
} catch (SignatureException e) {
String error = "Error in signature";
//do not log
throw new APIManagementException(error);
}
}
