2、AES 对称加密 只有一把密码 AES分为几种模式,比如ECB,CBC,CFB等等,这些模式除了ECB由于没有使用IV而不太安全,其他模式差别并没有太明显。 IV称为初始向量,不同的IV加密后的字符串是不同的,加密和解密需要相同的IV。但是由于块的长度是16字节,所以一般可以认为需要的IV是16字节。 PADDING AES块加密说过,PADD...

I am not an expert so someone else needs to clarify, but isn’t GCM one of those modes that uses AES only as a random generator, and so not susceptible to this attack? I guess the big question is, for those of us who liked what we thought was the margin of safety provided by ...
