Did you ever find a resolution to this issue?

bentoo commented on August 26, 2024

I was able to resolve this issue by using BouncyCastle 1.46

http://central.maven.org/maven2/org/bouncycastle/bcprov-jdk16/1.46/bcprov-jdk16-1.46.jar

from applepay_crypto_demo.

I talked to the CryptoWorkshop team that built the BouncyCastle library and they gave me the following fix:

PEMParser pemReaderPublic = new PEMParser(new StringReader(ephemeralPubKeyStr));
SubjectPublicKeyInfo ephemeralPublicKeyInfo = (SubjectPublicKeyInfo)pemReaderPublic.readObject();

ECPublicKey ephemeralPublicKey = (ECPublicKey)new JcaPEMKeyConverter().setProvider("BC").getPublicKey(ephemeralPublicKeyInfo);

So many thanks,bentoo. I use the following code for retrieving ECPublicKey:

KeySpec keySpec = new X509EncodedKeySpec(ephemeralPublicKey_bytes);
KeyFactory keyFact = KeyFactory.getInstance("EC", Security.getProvider("BC"));
PublicKey pubKey = keyFact.generatePublic(keySpec);
ephemeralPublicKey = (ECPublicKey)pubKey;

that runs well
