从 PHP 7.0 升级到 PHP 7.1 废弃了一个在过去普遍应用的扩展(mcrypt),但是微信官方提供的消息加密解密算法中的核心部分中确实使用 mcrypt 的,Prpcrypt class 的加密方法(encrypt)和解密方法(decrypt),怎么改成 openssl 的函数呢?

I encrypted a string with EVP_aes_128_cbc cipher, then changed the 1st byte of the ciphertext, and decrypt this changed ciphertext. Unexpectly, it didn't decrypt error or get a fully wrong result, but got a wrong 1st 16 bytes and same string of rest. Here is the encrypt func: ...
GCM是认证加密模式中的一种,它结合了上述两者的特点(GCM中的G就是指GMAC,C就是指CTR),能同时确保数据的保密性、完整性及真实性,另外,它还可以提供附加消息的完整性校验,加密流程如下图: 就像CTR模式下一样,先对块进行顺序编号,然后将该块编号与初始向量(IV)组合,并使用密钥k,对输入做AES加密,然后,将加密的...
