Web当时他们三人都在麻省理工学院工作。RSA 就是他们三人姓氏开头字母拼在一起组成的。但是，如果加密数据比较长的话，可能会出现问题，如：javax.crypto.IllegalBlockSizeException: Data must not be longer than 117 bytes. 1、问题重现. 我们可以编写一个 RSA 的简单实现，如： WebRSA padding should always be used, and it has a minimum size of dozens of bytes, as opposed to a single byte with most block cipher paddings. 2. Can the message size be any byte length or must it be a certain byte length to use RSA encryption? Using a single RSA operation you can only encrypt a small constant amount of bytes (100 or so).
