“too much data for rsa block”这个错误通常出现在使用RSA加密算法对大量数据进行加密时。RSA算法是一种非对称加密算法,它有一个固有的限制,即待加密的数据块大小不能超过密钥长度(以字节为单位)减去必要的填充(padding)空间。例如,如果使用2048位的RSA密钥,那么理论上最大可以加密的数据块大小约为256字节(2048位...
public static String decryptRSA(String str, String privateKey) throws Exception { Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); Cipher rsa = Cipher.getInstance("RSA/ECB/PKCS1Padding", "BC"); rsa.init(Cipher.DECRYPT_MODE, getPrivateKey(privateKey)); byte[] s =...
否则你可能会像笔者似的遇到Java.lang.ArrayIndexOutOfBoundsException: too much data for RSA block异常。遇见这个异常，你需要先确定你给Cipher 加密的明文(或者需要解密的密文)是否过长；排除掉明文(或者密文)过长的情况，你需要考虑是不是你的Cipher 线程不安全了。
你这个解决了吗？同问

On the receiving end, the encrypted symmetric key is decrypted using the RSA private key, and then the decrypted symmetric key is used to decrypt the data. Conclusion The “too much data for RSA block” error occurs when trying to encrypt large amounts of data with RSA encryption. To handl...
