概述

如美國(guó)聯(lián)邦信息處理標(biāo)準(zhǔn)出版物197中所定義的,aes實(shí)現(xiàn) AES 加密(以前稱(chēng)為 Rijndael)。

這個(gè)包中的 AES 操作不是使用恒定時(shí)間算法實(shí)現(xiàn)的。在支持 AES 的硬件支持的系統(tǒng)上運(yùn)行時(shí)會(huì)有一個(gè)例外,這些操作會(huì)使這些操作保持恒定時(shí)間。例子包括使用 AES-NI 擴(kuò)展的 amd64 系統(tǒng)和使用 Message-Security-Assist 擴(kuò)展的 s390x 系統(tǒng)。在這樣的系統(tǒng)中,當(dāng) NewCipher 的結(jié)果傳遞給 cipher.NewGCM 時(shí),GCM 使用的 GHASH 操作也是恒定的。
