InvalidKeyException: Wrong key size 异常通常是在使用加密算法时,由于提供的密钥尺寸不符合算法的要求而触发的。以下是一些解决此异常的步骤和建议: 1. 确认异常类型 异常类型已经明确为 InvalidKeyException: Wrong key size,这通常发生在加密或解密操作中,当使用的密钥不符合算法对密钥
我是觉得使用DES加密算法时,它一直显示key的字节长度不对,就想着换一种表述方式,又看到了别的友友的经验分享,就换成这样试了试(直接放进main主函数里面就能运行): Stringtext="123"; SecretKeySpec sks=newSecretKeySpec(password.getBytes(),"DES"); Cipher c=Cipher.getInstance("DES"); c.init(Cipher.ENC...
PublicKey publicKey = keyPair.getPublic(); //生成私钥 PrivateKey privateKey = keyPair.getPrivate(); //获取字节数组 byte[] privateencoded = privateKey.getEncoded(); byte[] publicencoded = publicKey.getEncoded(); // 使用base64 转码 String privateKeyEncoded = String.valueOf(Base64.encode(pri...
SecretKeySpec secretKey = new SecretKeySpec(key, algorithm); 如果是用密匙工厂就可以用非十六进制字符串的key SecretKeyFactory keyFactory = SecretKeyFactory.getInstance(algorithm); DESKeySpec desKey = new DESKeySpec(key); SecretKey secretKey = keyFactory.generateSecret(desKey); ...

Possible Reasons forjava.security.InvalidKeyException: Illegal key size This error means that our Java Virtual Machine (JVM) is using a policy that permits limited cryptography key sizes only due to the US export laws. Now, the point is, why are we getting this error? Two possibilities are gi...
