I got stuck in a strange problem. I always failed to install my applet no matter in JCIDE simulator or in real card.
But I found that when I annotated this code line, it can run w/o any problem.

Code: Select all

HMACKey hmacKey = (HMACKey) KeyBuilder.buildKey(KeyBuilder.TYPE_HMAC,KeyBuilder.LENGTH_HMAC_SHA_1_BLOCK_64, false);

Does this line have any problem?

It might be because either JCIDE simulator or your real card doesn't support the algorithm or key size.

JCIDE doesn't support HMAC. You can use SHA1 instead.

Can you show me a sample code of SHA1? If any example exists, I would be greatly appreciated.
