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.

Thank you for all help. I have run JCAlgTest and my card supports ALG_ECDSA_SHA256 mode. :lol:
