考虑这个方法
declare @pswd nvarchar(max);
set @pswd = '2YKRCqHv';
Select
orig = a.Hash,
hashA = 0x0200 + a.Salt + Hashbytes('SHA2_512', cast('2YKRCqHv' as varbinary(max)) + a.Salt),
hashB = 0x0200 + a.Salt + Hashbytes('SHA2_512', cast(@pswd as varbinary(max)) + a.Salt)
from DB a
where
a.Hash =
0x0200 + a.Salt+ Hashbytes('SHA2_512', cast('2YKRCqHv' as varbinary(max)) + a.Salt)
or
a.Hash =
0x0200 + a.Salt+ Hashbytes('SHA2_512', cast(@pswd as varbinary(max)) + a.Salt)
输出：
orig 0x0200BB316075603286E929221B9C04411AEC602A98B295CC05FCFFA809C2B553A100F4EBD4AA6FB3458E0B7C7E6D6B36FEA4908DF0AECA5142A26FA06B30F125253E15D585EE
hashA 0x0200BB316075603286E929221B9C04411AEC602A98B295CC05FCFFA809C2B553A100F4EBD4AA6FB3458E0B7C7E6D6B36FEA4908DF0AECA5142A26FA06B30F125253E15D585EE
hashB 0x0200BB316075C91147A2AEC396358C3F950C7E930B8DF0F9AC05628E00A74663502EE7BFCE68AA7BA3EC8303AE65107C72CAEF95111DD85CE45F210291B2800141CA37863A09
为什么A和B不同？我该如何创建验证密码程序？
答案 0 :(得分：1)
这是因为hashA CAST VARCHAR VARBINARY hashB CAST NVARCHAR VARBINARY declare @pswd nvarchar(max);
set @pswd = '2YKRCqHv';
Select
orig = a.Hash,
hashA = 0x0200 + a.Salt + Hashbytes('SHA2_512', cast(N'2YKRCqHv' as varbinary(max)) + a.Salt),
hashB = 0x0200 + a.Salt + Hashbytes('SHA2_512', cast(@pswd as varbinary(max)) + a.Salt)
from DB a
where
a.Hash =
0x0200 + a.Salt+ Hashbytes('SHA2_512', cast(N'2YKRCqHv' as varbinary(max)) + a.Salt)
or
a.Hash =
0x0200 + a.Salt+ Hashbytes('SHA2_512', cast(@pswd as varbinary(max)) + a.Salt)
N HashA到@pswd。
第一个是非Unicode，因此不同。
尝试：
VARCHAR请注意在orig的密码前添加temp = split("A BUYS: PRODUCT @ 85 / B SELLS"," ")
A = temp(0)
Product = temp(2)
qty = temp(4)
B = temp(6)
，这会导致它成为Unicode，然后生成相同的结果。
或者，更改.Photos > a > #HoverImg:last-child声明以使用.index-page .Photos a img，其产生与function HeightCalc(x, n) {
$(x).each(function() {
var Calc = ($(this).height() + 50) / 2; // Calculate height of images
$(this).siblings(n).css({
"bottom": Calc
}); // Move divs according to calc. total
});
}
HeightCalc(".index-page .Photos a img", ".HoverImg");
相同的输出。
