Re: Keepass NFC Applet
The security of the KeepassNFC applet is insufficient for NFC application and I would probably recommend that only standard ISO7816 contact channel be used and even if contact channels are used, it is still vastly insufficient in terms of security. The reasons: * Lack of PIN access * Sloppy use of R...

Re: Basic question on digital signature
It depends but RSA 2048 and above and ECDSA 256 and above are generally used as baseline.

Re: Basic question on digital signature
Signature algorithms (RSA, ECDSA, DSA) is one thing and Signature Methods (PKCS1 1.5/ OAEP) is another thing. To put it very simplistically, the algorithm is a set of mathematical formula on how you should create a signature (maths and numbers). A method on the other hand is that every algorithm may...

Re: Session key
Here's my method of designing a Secure Channel Protocol customized for your own application. THE A02 SCP PROTOCOL ==================== Assumptions: - APDU buffer at least 256 bytes - RSA-2048-PKCS1-1_5 Cipher is available - AES-256 in ECB and CBC mode is available Tested & Proven Hardware: - Fei...

Re: Q with eJava Token
The eJavaToken specs I know of is:
- 1.96KB User RAM
- 135KB NVM
From a Feitian catalogue I received from those guys a while back.
The 110KB NVM and 1.6 KB RAM in the shopping page is lesser than the specs that are from the Feitian catalogue. Am I mistaking something ?

Re: Session key
There are two options to approach card session encryption. 1.) SCP 02/03 as per GlobalPlatform specifications. Note that SCP encryption only encrypts the APDU Command data (without the headers - CLA, INS, P1, P2, LC) sent from the host computer to the card while the response is not encrypted. MAC-in...

Re: Session key
Are you trying to use the SCP02/03 and trying to find their session keys ? What kind of session keys are you trying to find ? You need to put more detail into your question as it's too abstract for us to know how to reply your question.

Re: 6C 0B - Unknown Error ( DEBUG )
Please use the Code tag for your APDU request/response and codes to make it easier for forum members to read.
Thanks.
Thanks.

Re: Including new Packages
Thank you. If you succeed, do recommend JavaCardOS to stock up some in their store so that the community will have something new to experiment with as well.

Is it even possible to purchase G&D cards directly from G&D ? I have never successfully purchased any directly from G&D, Gemalto and so on.
If you successfully purchased G&D cards, I would like to get some too.
