I can get a key that works for decryption if I also pass the d instead of the final NULL, like RSA_set0_key(rsa, n, e, d). (PEM_write_RSAPrivateKey() also returns 0 and prints nothing for the key I create with that method, however) I have added the code below as a test t...
也就是说,如果我们定义的密钥(我们可以通过 java.security.KeyPairGenerator.initialize(int keysize) 来定义密钥长度)长度为 1024(单位是位,也就是 bit),生成的密钥长度就是 1024位 / 8位/字节 = 128字节,那么我们需要加密的明文长度不能超过 128字节 - 11 字节 = 117字节。也就是说,我们最大能将 117 字...
