OpenJDK 27 · sun.security.jgss.krb5.WrapToken_v2 · APIdia, the JavaDoc alternative

This class represents the new format of GSS tokens, as specified in RFC 4121, emitted by the GSSContext.wrap() call. It is a MessageToken except that it also contains plaintext or encrypted data at the end. A WrapToken has certain other rules that are peculiar to it and different from a MICToken, which is another type of MessageToken. All data in a WrapToken is prepended by a random confounder of 16 bytes. Thus, all application data is replaced by (confounder || data || tokenHeader || checksum).
