Load a RSA private key in Java (algid parse error, not a sequence)

Question

I\'m trying to load a private RSA key generated with ssl into java, my code is:

Generate the key:

openssl genrsa -out mykey.pem 1024         


        

Answer 1

You could still load the keys if necessary,

public static PublicKey bigIntegerToPublicKey(BigInteger e, BigInteger m)  {
    RSAPublicKeySpec keySpec = new RSAPublicKeySpec(m, e);
    KeyFactory fact = KeyFactory.getInstance("RSA");
    PublicKey pubKey = fact.generatePublic(keySpec);
    return pubKey;
}

public static PrivateKey bigIntegerToPrivateKey(BigInteger e, BigInteger m) {
    RSAPrivateKeySpec keySpec = new RSAPrivateKeySpec(m, e);
    KeyFactory fact = KeyFactory.getInstance("RSA");
    PrivateKey privKey = fact.generatePrivate(keySpec);
    return privKey;
}

all you need is the modulus and the exponent.
