Cipher.init 1

Web实例化Cipher对象时，只指定算法(RSA)，而不指定填充。因此，填充将使用与提供程序相关的默认值。 因此，填充将使用与提供程序相关的默认值。 为了避免无意中使用不正确的填充和跨平台问题，还应该显式地指定填充(例如， RSA/ECB/PKCS1Padding ). WebEVP_CIPHER_CTX_init () initializes cipher contex ctx. EVP_EncryptInit_ex () sets up cipher context ctx for encryption with cipher type from ENGINE impl. ctx must be initialized before calling this function. type is normally supplied by a function such as EVP_aes_256_cbc ().
