java card- ECDSA signature

Post by Usiger » Wed Oct 19, 2016 11:37 pm

I have a java card. And I found that this card supports ECC over GF(p) for keys up to 320 bits and SHA-256 as well. Does this mean that the card supports ECDSA signature mode such as ALG_ECDSA_SHA256? Thanks for any help.

Generally speaking, your card will support ALG_ECDSA_SHA256 as well. But it really depends on the implementation.

Run JCALGTest on your card and you can get all the supported terms from the test result.
