Re: Is it possible to use ALG_HMAC_SHA1 in JC2.2.1?
You could just use the value that you find in the JC2.2.2 version for the constant ALG_HMAC_SHA1 (= (byte)24) and pass it to the Signature.getInstance() method. So using the value is not a problem. However, the smartcard must support this algorithm in order for you to be able to use. @horse dream ,...
