Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

installation got error 0x6444 while calling buildKey more than 45 times in constructor

Post by JavaCardVE » Tue Jun 26, 2018 6:40 am

I have an applet using buildKey for 100 times in constructor.It would be able to save 100 keys and used them.
but in installation time igot error 0x6444 (in Fudan javacard)

When I decrease buildkey from 100 times to 45 times, the installation is successful.
I use the fallowing algorithm for buildkey.

Code: Select all

SAMMasterKeys[i] = (DESKey) KeyBuilder.buildKey(KeyBuilder.TYPE_DES,KeyBuilder.LENGTH_DES3_2KEY, false);   


I want to know what happens to card(software,hardware,middle-ware,...) that this error occurred.

I have a jemalto card and the applet can install successfully(with 100 times buildkey).

Maybe Fudan card has no enough space to build 100 keys :?:

it looks like there is not enough RAM(COD or COR).
