“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...
including SSL/TLS, SSH, and PGP. However, when working with large amounts of data in Android, you may encounter the “too much data for RSA block” error.

今天在做RSA加密的时候遇到了一个这样的错误:ArrayIndexOutOfBoundsException: too much data for RSA block 查询相关资料后得知该错误是加密数据过长导致的。 加密数据长度 <= 模长-11 解决办法:将要加密的数据截取后分段加密 下面是关于RSA算法密钥长度/密文长度/明文长度的介绍 本文转自:http://blog.sina.com....
Cipher。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

You can even use a blockchain to assign names and bind them to public keys. The only thing that's truly mandatory if you're building a PKI from scratch is that, definitionally, you've got to be using public keys. Everything else can change....
