I'm trying to generate a key pair using the /java bouncy castle 1.52 implementation for curve 25519 what gives me
java.lang.IllegalArgumentException: string curve25519 not an OID
Here is my code:
public KeyPair generateKeys() throws NoSuchAlgorithmException,
NoSuchProviderException, InvalidAlgorithmParameterException {
ECParameterSpec ecSpec = ECNamedCurveTable.getParameterSpec("curve25519");
KeyPairGenerator g = KeyPairGenerator.getInstance("ECDSA", "BC");
g.initialize(ecSpec, new SecureRandom());
return g.generateKeyPair();
}
the result of this code is a stacktrace below:
java.lang.IllegalArgumentException: string curve25519 not an OID at org.bouncycastle.asn1.ASN1ObjectIdentifier.(Unknown Source) at org.bouncycastle.jcajce.provider.asymmetric.ec.BCECPublicKey.getEncoded(Unknown Source) at org.bouncycastle.jcajce.provider.asymmetric.ec.BCECPrivateKey.getPublicKeyDetails(Unknown Source) at org.bouncycastle.jcajce.provider.asymmetric.ec.BCECPrivateKey.(Unknown Source) at org.bouncycastle.jcajce.provider.asymmetric.ec.KeyPairGeneratorSpi$EC.generateKeyPair(Unknown Source) at com.poc.databank.encryption.BouncyCastleEncryption.generateKeys(BouncyCastleEncryption.java:22) at com.poc.databank.encryption.BouncyCastleTest.testApp(BouncyCastleTest.java:16) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:47) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:44) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:271) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:70) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:238) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:63) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:236) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:53) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:229) at org.junit.runners.ParentRunner.run(ParentRunner.java:309) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)
I checked the bouncy castle code and figured out that the curve25519 is registered in CustomNamedCurves class as
defineCurve("curve25519", curve25519);
but not as
defineCurveWithOID("secp192k1", SECObjectIdentifiers.secp192k1,
secp192k1);
I understand that there should be a reason for this. Please help me to found out a way how I can generate a key pair uising curve25519.
