rev 59107 : imported patch security


  90  *    i32 strlen(string) + 1
  91  *    octets of string, with the \0x00 ending
  92  *
  93  * The old style block is always created by MIT krb5 used even if a new style
  94  * is available, which means there can be 2 entries for a single Authenticator.
  95  * Java also does this way.
  96  *
  97  * See src/lib/krb5/rcache/rc_io.c and src/lib/krb5/rcache/rc_dfl.c.
  98  *
  99  * Update: New version can use other hash algorithms.
