gssapi - Exporting GSSCredential to byte array and vice versa -


i implementing s4u protocol using gss in java. since java 7 not support protocol, plan write jni wrapper on gss api methods in c not have equivalent in java.

as part of writing jni on gss_acquire_cred_impersonate_name described in http://k5wiki.kerberos.org/wiki/projects/services4user#gss_acquire_cred_impersonate_name .

this method takes populated input credential handle (gss_cred_id_t) , populates output credential handle. in java code have gsscredential created need pass c function in form of gss_cred_id_t , convert output credential handle gss_cred_id_t gsscredential further use.

how can export gsscredential object byte array , vice versa in order communicate c function ?

thanks

  1. you should rather java 8 code, has built-in support.
  2. export cred custom extension gss-api , therefore not available. globus jgss implementation support extension.
