According to the JavaCard 2.1 API,
Interface DESKey contains an 8/16/24 byte key for single/2 key triple
DES/3 key triple DES operations. And Gemxpresso 211is states that it
supports only security algorithm of 3-DES.
Hence, is it true that Gemxpresso 211is can only manipulate the DES key
with
length at most *24* byte?
By the way, if I want to generate a 3-DES key with KeyGenerator in
package javax.crypto, its length must be 112 bits. The problem is how
can I generate the 3-DES key with correct length (off-card) that can
work on Gemxpresso 211is.
