 == Add ECDH-ES support to JwtBuilder
 
-Open Liberty has enhanced its JSON Web Token 1.0 (`jwt-1.0`) feature by introducing support for ECDH-ES (Elliptic Curve Diffie-Hellman Ephemeral Static) as a key management algorithm in the JwtBuilder configuration. This update allows application developers to use Elliptic Curve Cryptography for encrypting the Content Encryption Key (CEK) of a JWE, providing a modern alternative to the previously supported RSA-OAEP with enhanced security.To use ECDH-ES, developers must define an Elliptic Curve public key in the keyManagementKeyAlias attribute.The EC public and private key pair can be generated using securityUtility or keytool, for example:
-  - `./securityUtility createSSLCertificate --sigAlg=SHA256withECDSA --keySize=256 --server=myServer --validity=3650 --password=password`
-  - `keytool -genkeypair -alias eccert -keyalg EC -groupname secp256r1 -validity 3650 -storetype pkcs12 -keystore myKeystore.p12 -storepass password`
-ECDH-ES can be configured under the `keyManagementKeyAlgorithm` attribute in a JwtBuilder element of `JSON Web Token 1.0` (`jwt-1.0`) feature.The EC public key used for encryption must be referenced by its alias in `keyManagementKeyAlias`, and the keystore must be specified using the `trustStoreRef` attribute.
-Sample server.xml configuration:
