Hi Team,
I get "java.security.spec.InvalidKeySpecException: key spec not recognised"
exception while running it in carbon component but the same code (library)
works fine as a self contained web application.
I am using "buncycastle" library to decode public key.
here is the code:
public PublicKey decodePublicKey(byte[] encodedPublicKey) throws
U2fException {
try {
X9ECParameters curve = SECNamedCurves.getByName("secp256r1");
ECPoint point;
try {
point = curve.getCurve().decodePoint(encodedPublicKey);
} catch (RuntimeException e) {
throw new U2fException("Could not parse user public key",
e);
}
return KeyFactory.getInstance("ECDSA").generatePublic(
new ECPublicKeySpec(point,
new ECParameterSpec(
curve.getCurve(),
curve.getG(),
curve.getN(),
curve.getH()
)
)
);
} catch (InvalidKeySpecException e) {
throw new U2fException(ERROR_DECODING_PUBLIC_KEY, e);
} catch (NoSuchAlgorithmException e) {
throw new U2fException(ERROR_DECODING_PUBLIC_KEY, e);
}
}
online resources suggests its because class loading issues[1
<http://www.bouncycastle.org/jira/browse/BJA-131>], also the provider
installation guide[2
<http://www.bouncycastle.org/wiki/display/JA1/Provider+Installation>].
I tried installing JCE provider to jre, didn't help. web application is
working without installing the provider
need information regards JCE provider class loading and security policy
details in carbon.
