TEA 编码算法的 PLAN9 汇编优化实现
|
||
|
||
## 1.17 版本及以上
|
||
代码与[MiraiGo](https://github.com/Mrs4s/MiraiGo/blob/574c4e57b1467225f03936342e477ee0d587a2dc/binary/tea.go)相比，替换了加密算法为`runtime.fastrand`，提升速度如下。

## 1.16 版本及以下
|
||
使用 PLAN9 汇编编写`Encrypt`，内联编写`Decrypt`，替换了加密算法为`runtime.fastrand`，与[MiraiGo](https://github.com/Mrs4s/MiraiGo/blob/574c4e57b1467225f03936342e477ee0d587a2dc/binary/tea.go)代码同在`go1.16`版本下编译相比，提升速度如下（new16.txt）。

可见在编码时，在`go1.16`版本下的某些时候（编码大小在`0-16kb`之间），`gofastTEA`比`go1.17`版本的`MiraiGo`实现更快，且整体来看，`gofastTEA`在`go1.16`版本下的执行效率已经可以与`MiraiGo`实现的`go1.17`版本基本持平。 |
