在这里解密报错cn.hutool.crypto.CryptoException: InvalidCipherTextException: invalid cipher text 跟踪源码之后发现是 这个地方2执行完抛出异常,公钥和私钥包括密文都是正确的,同样的代码放到另外一个项目里面可以正常解密,但是在这个项目里面就不行,一个星期前还是OK的,代码没用改动,有没有大神知道是因为什么?
实现代码如下: importorg.bouncycastle.asn1.x9.ECNamedCurveTable;importorg.bouncycastle.asn1.x9.X9ECParameters;importorg.bouncycastle.crypto.InvalidCipherTextException;importorg.bouncycastle.crypto.engines.SM2Engine;importorg.bouncycastle.crypto.params.ECDomainParameters;importorg.bouncycastle.crypto.params.ECPri...

在JAVA中,我们可以使用Bouncy Castle库来实现SM2算法的加解密操作。下面是一个简单的示例代码: SM2加密 importorg.bouncycastle.crypto.AsymmetricCipherKeyPair;importorg.bouncycastle.crypto.InvalidCipherTextException;importorg.bouncycastle.crypto.engines.SM2Engine;importorg.bouncycastle.crypto.params.AsymmetricKeyParameter...
} catch (InvalidCipherTextException e) { e.printStackTrace(); return null; } } /** * 根据privateKey对加密数据encodedata,使用SM2解密 */ public static byte[] decrypt(byte[] encodedata, PrivateKey privateKey) { SM2Engine localSM2Engine = new SM2Engine(); ...
您好,经过以上代码,解决了java无法解密gmssl生成的密文的问题,但是java端生成密文,然后调用encodeSM2CipherToDER方法进行编码,gmssl却无法解密,报invalid ciphertext,能否指点一下呢 zhangjinghao3年前 大佬,您这个的完整解决代码有么,fixToCurveLengthBytes()这个方法在这里没找到。
