Http://www.jiamisoft.com/blog/11238-liumeitijiamijishu.htmlWith the rapid development of Internet and the popularization of Internet Multimedia application, the protection of digital copyright and right of privacy has become a more and more concern,

1 sha Encryption: Secure Hash algorithm is mainly applicable to digital signature algorithms (Digital Signature algorithm DSA) defined in the digital signature standard (Digital Signature Standard DSS). For messages that are less than 2^64 bits in

The main purpose of this article is to realize the digital signature problem of PDF, just as a summary of my learning knowledge.1. Overview of digital Signature AlgorithmThis section mainly refers to: 75007189Digital signature: The private key is

Preface 32-bit and 64-bit systems are often mentioned in the computer field, but many people do not know the difference between 32-bit and 64-bit systems. Therefore, I have compiled some documents online, I hope to share with you. For 32-bit and

Supported DES encryption for IOS and java   Recently, we are considering data encryption requirements. So I simply read about Data Encryption. Of course, it is not about the principle, but about how to implement it. Now we need to implement the

The DES algorithm has three entry parameters: Key, Data, Mode. Where key is 8 bytes A total of 64 bits, is the working key of the DES algorithm, the data is 8 bytes 64 bits, is to be encrypted or decrypted, the mode for DES works, there are two

The first time after working with the Java encryption mechanism, the requirement is to use RSA digital signature. At that time, after seeing a face of a confused force, looked up all kinds of information.For the learning process I took a lot of

Here is a simple way to use Zend Guard to encrypt our PHP source code. The current version of Zend Guard is 6.0, download address: http://www.zend.com/en/products/guard/downloads Detailed English document description is here: http://files.zend.com/
