Package aes implements AES encryption (formerly Rijndael), as defined in U.S. Federal Information Processing Standards Publication 197.
aes 包实现了 AES 加密(以前称为 Rijndael),如美国联邦信息处理标准出版物 197 中所定义。
The AES operations in this package are not implemented using constant-time algorithms. An exception is when running on systems with enabled hardware support for AES that makes these operations constant-time. Examples include amd64 systems using AES-NI extensions and s390x systems using Message-Security-Assist extensions. On such systems, when the result of NewCipher is passed to cipher.NewGCM, the GHASH operation used by GCM is also constant-time.
此包中的 AES 操作并非使用恒定时间算法实现。例外情况是在启用了对 AES 的硬件支持的系统上运行时,这使得这些操作成为恒定时间。示例包括使用 AES-NI 扩展的 amd64 系统和使用消息安全辅助扩展的 s390x 系统。在这些系统上,当 NewCipher 的结果传递给 cipher.NewGCM 时,GCM 使用的 GHASH 操作也是恒定时间的。

函数
func NewCipher

NewCipher creates and returns a new cipher.Block. The key argument should be the AES key, either 16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.
NewCipher 创建并返回一个新的 cipher.Block。key 参数应为 AES 密钥,16、14 或 32 字节,以选择 AES-128、AES-192 或 AES-256。
