我正在尝试将一把加密的ECC gpg密钥转换为相应的Java类ECPrivateKey/ECPublicKey。
我使用以下命令生成密钥对:
然后选择(3)NIST P-256
结果如下:
我使用以下命令生成密钥对:
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
结果如下:

我该如何将这个加密文本格式转换为有效的java.security.interfaces.ECPrivateKey和java.security.interfaces.ECPublicKey类?
我的最终目标是以以下方式进行签名:
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)
jwsObject.signature
}
