Re: RSA 4096

Look at the J3H145 card.

You need to ask @JavaCardOS to enable 4096 bits RSA by the way.

So we had to replace the convertor ,used older version of convertor. Yup that's where my second post above talks about how to mitigate th...

Re: how to set project configuration

Here's a workaround I figured out. You will need to build and clean the project as usual even if it continues issue the jc.home not set error. This will not affect the next steps as long as the compilation is clean without errors. jc.home error is due to problems in JCIDE's packaging and can be corr...

Re: how to set project configuration

Hi,

I am also stuck with 'error: Java property "jc.home" is not set.' error while creating an applet that uses Shareable interface.

I am currently running JC 3.0.4.

Do you have the steps to remedy the problem like how to replace Feitian's converter ?

Re: The difference between SHA, AES and RSA algorithm?

SHA -> digital data one way hashing.
AES -> digital content confidentiality protection via data scrambling.
RSA -> digital data confidentiality protection via data scrambling and also digital identity attestation and digital content verification via digital signatures.

Re: The ALgorithm of RSA Sample Code

@sdellava, I would recommend you to read about asymmetric cryptography and start from learning basic cryptography first and how they work. Public keys are used to encrypt a message and not for decrypting messages. Private keys are the ones you must turn to for decrypting messages. You will not be ab...
