I am trying to sign a message with the following Siganture. I know that my card support this signature, but I got the exception NO_SUCH_ALGORITHM

Code: Select all

Signature sig = Signature.getInstance(Signature.ALG_RSA_SHA_256_PKCS1_PSS, false);

And this one can work fine.

Code: Select all

Signature sig = Signature.getInstance(Signature.ALG_RSA_SHA_256_PKCS1, false);

So I guess that there is some problem with the PSS scheme. How can I solve this problem to make it work?

Update: my java card version 3.0.1

The card hardware may not support the one you want. Ask card vendor for details.

Hi, there is no guarantee that the card vendor should implement all given cryptographic mechanism supported by JavaCard. That is, JavaCard 3.0.1 supports several RSA-PSS signature types, but the card might not support all the types.

You can use AlgTest to check if your card support the signature type .
