My FlexSecure Journey

Just an “important” update

I have been doing a bit of testing recently with my AliExpress Java card that I linked above, Although it works, It is not a direct comparison to the FlexSecure.

Details

Global Platform information:

Java Card version 2.3
Global Platform version 2.3
GP Secure Channel Protocol: 02 option 55
Max. length APDU data field: 255 bytes
Global Platform card manager

Turns out, its a much older version of what Dangerous Things supply here

The DT Version is running 3.0.5

So, whilst the Aliexpress card:

  • will work with SOME Applets
  • It cant be updated (Factory Set)
  • It has some limitations.

So if you have the AliExpress card already, just know that you wont be able to load the full gamut of applets, But, if you are looking at getting a test card, save yourself a headache just go for the DT Java Card Version.

I am upgrading my card so I can do “All the things”

I’ll edit my link above
