问题描述
我需要生成唯一的ID为我的应用程序,我正在寻找合适的算法。我想preFER这样的事 -
I need to generate unique ids for my application and I am looking for suitable algorithms. I would prefer something like this --
YYYY + MM + DD + HH + MM + SS +<随机盐GT; +<东西从preceding值&GT而得;
F.ex。 -
20100128184544ewbhk4h3b45fdg544
我想使用 SHA-256
或东西,但结果字符串应该不会太长。我可以使用 UUID
但同样,他们太长时间,他们都保证是唯一的只有一台机器。
I was thinking about using SHA-256
or something but the resultant string should not be too long. I could use UUID
but again, they are too long and they are guaranteed to be unique on only one machine.
我欢迎建议,想法。我的编程语言是Java。
I would welcome suggestions, ideas. My programming language is Java.
编辑:的id不需要加密安全。我期待在简单的散列交易算法像一个由丹·伯恩斯坦等。
The ids need not be cryptographically secure. I am looking at simpler hashing algos like the one by Dan Bernstein, etc.
推荐答案
所以,我终于解决了这一点 -
So I have finally settled for this -
d = YYYYMMDDHHMMSS
hash = d + sha256(d + random_salt)[:10]
感谢大家的响应。
这篇关于算法生成唯一的(可能是自动递增的)IDS的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
