We have a question for you, regarding possibility to implement NTAG Originality Signature Validation in JCOP Java Card J3D081.
It seems that we have no way to do ECDSA signature verification in J3D081 without using SHA1 or SHA2 digest algorithm.
Is there any way to execute ECDSA signature verification without using digest algorithm?
If this is not possible with J3D081, please recommend us a Java Card product that would support this.
