我正在尝试将装甲ECC gpg密钥转换为相应的java类ECPrivateKey/ECPublicKey.

要生成我正在使用的密钥对: gpg --expert --full-generate-key

然后选择(9)ECC和ECC(或(10)ECC(仅签名))

然后选择(3)NIST P-256

导致:

如何从这种装甲文本格式获得有效的java.security.interfaces.ECPrivateKey和java.security.interfaces.ECPublicKey java类？

我的最终目标是以下列方式登录:

String createSignatureFromJson(String jsonPayload, byte[] privateKey) {
        Payload payload = new Payload(jsonPayload)
        def key = privateKeyParse(privateKey)

        JWSSigner signer = new ECDSASigner((ECPrivateKey)key)
        JWSHeader header = new JWSHeader.Builder(JWSAlgorithm.ES256).build()

        JWSObject jwsObject = new JWSObject(header, payload)
        jwsObject.sign(signer) …

我试图在需要GPG版本> 2.1的GPG ECC（NIST P-256）密钥签名的源上使用apt-get

我怎样才能使apt-get使用gpg2代替gpg？（混叠不起作用）
