Hi,
I am trying to use ECIES mechanism for cryptography and when I am running the below code I am geting error Illegal key size or default parameters
Security.addProvider(new BouncyCastleProvider());
// NOTE just "EC" also seems to work here
KeyPairGenerator kpg = KeyPairGenerator.getInstance("ECIES");
kpg.initialize(new ECGenParameterSpec("secp256r1"));
// Key pair to store public and private key
KeyPair keyPair = kpg.generateKeyPair();
Cipher iesCipher = Cipher.getInstance("ECIES");
iesCipher.init(Cipher.ENCRYPT_MODE, keyPair.getPublic());
The last line is giving the error. Please find below the error
Exception in thread "main" java.security.InvalidKeyException: Illegal key size or default parameters
at javax.crypto.Cipher.checkCryptoPerm(Cipher.java:1026)
