我将就两个因素认证进行最后年度项目,第二个因素作为用户名/密码的数字证明。 我的想法是,在网络应用方面,如何用数字插头样本在 Java这样做。 是否有办法可以使用任何密码算法? 与数字标签有关的缺点是什么? 请让我提供一些细节。
易于使用的是x.509证书。 页: 1 JavaTM PKI Programmer s Guide, 如同它一样,对使用x.509份证书所必需的Java/60/8s进行了很好的概述。 很多 Java开发商使用Bouncy城堡, 用于补充加密标本。
使用X.509证书的冰层是,几乎所有东西都支持这些证书。 你们可以很容易地将X.509客户证书放到大多数网络浏览器中,大多数网络服务器可以很容易配置起来接受。 建立自己的Certificate Authority TinyCA 方案。 ( opensl 指挥线工具为t awful,但丁 CA使得能够轻易获得一切权利。
The biggest downside to x.509 is probably the awkwardness involved in setting up your own CA -- so many programs have a list of CA Root Certificates that are baked into the program and supplying your own Root Certificate can be annoying -- somehow you have to transport that file to your clients in a manner that prevents tampering. (A task that would be easier if your CA root were already in the software.)
ctr mode makes it possible to use a block cipher as a stream cipher but how strong will be the encryption in this mode ?
I need help please. I started to program a common brute forcer / password guesser with CUDA (2.3 / 3.0beta). I tried different ways to generate all possible plain text "candidates" of a defined ASCII ...
I am using the Bouncy Castle Java cryptographic algorithm implementation. I am getting an IllegalKeySizeException. To overcome this I have even changed my java security jars (local_policy.jar and ...
I want to encrypt some server data using .NET s RSACryptoServiceProvider and decrypt it when someone enters a key/password via a web page. What are my options for protecting, or ideally not even ...
For each of our binary assets we generate a MD5 hash. This is used to check whether a certain binary asset is already in our application. But is it possible that two different binary assets generate ...
I used openSSL command to create 2 files: 1 for RSA public key & 1 for RSA private key. How do I recover RSA keys using C? Specifically, I have these functions: RSA_public_encrypt(read_num, ...
Hi i am trying to set up an RSA cryptosystem i have all the values except d selected prime numbers: p=1889, q=2003, n=3783667, phi=3779776, e= 61 i got stuck finding d could anyone help me to figure ...
This is a combinatorics question with some theory in hashing algorithms required. Let s say the input can be any random sequence of bytes 30 kB to 5 MB of size (I guess that makes quite a few ...
