分享一个sha256哈希加密字符串函数源码

冰原纪

实话说,网上抄的,源码为BV6.0的代码,按键基本毫无压力兼容.源码其中一个数组定义在函数内导致报错,修改后现已正常.

=======以下为源码=======
Private m_lOnBits(30)
Private m_l2Power(30)
Private K(63)
Dim lWordArray()

t1=Plugin.sys.GetTime()
密码 = "123456"
str = SHA256(密码)
TracePrint "密码hash加密=" & str & ",长度=" & len(str)
TracePrint Plugin.sys.GetTime()-t1
