And cryptography involves scrambling information, converting what you a human can read into sort of nonsense that hopefully a bad guy cannot read.
密码包含不规则的信息,它把我们正常人能读懂的东西转化为,希望坏人读不懂的东西。
And they created this like, really big form of cryptography that everybody uses.
他们发明了每个人都在使用的大型密码。
Fast forward mid-semester when we talk about cryptography and scrambling information, we need the ability to express ourselves in words, not just numbers, and we have that already.
回想一下期中的时候,我们讨论过密码学,和一些不规则信息,我们需要话语来表达自己,而不是数字,其实我们已经有了。
Yeah. I don't really know a whole lot of modern cryptography yet
嗯,目前我对现代密码学的了解还不多,
But I know today in my math class, we were learning about the guys who created RSA Public Key Cryptography.
但是今天的数学课上,我们在学习RSA公钥加密算法的创始人。
In Week 2 we'll look at things like cryptography and functions and the tools that by which you begin to assemble solutions to problems; in Week 3 we'll introduce what are generally ; known as algorithms and data structures; mechanisms by which you can solve problems more efficiently, effectively.
第2周,我们学习加密技术及其功能,还会学到一些操作工具,通过这些工具的使用来收集解决问题的办法,第3周,我们将介绍;,算法和数据结构,以及可以更有效地解决问题的机制。
The number that you choose to rotate your letters by is what we call in cryptography, a key.
你选择的旋转字母的数量,就是所谓的加密学,一个密钥。
Well, we'll talk before long about cryptography.
好,我们等下讲讲密码学。
There's cryptography going on.
这里就使用了密码技术。
Can you tell us what exactly cryptography is?
密码学究竟是什么呢?
But in society today, and we'll talk a bit about security topics -- and such throughout the course, for cryptography -- for encrypting things like your credit card information and bank accounts -- you don't use 32 bits, you don't use 64 bits, you generally use 1024 bits, 4,048 bits.
但在当今的社会上,我们将讨论一点安全方面的知识,贯穿整个课程,密码学-,加密一些像信用卡信息,银行账号之类的东西--你不能用32位,你也不能用64位,你通常要使用1024位,4048位。
