sha 2 hash generator

The DH key exchange of SSH is a set of key exchange algorithms for several complex algorithms. The algorithm called Diffie-hellman-groupx-exchange-shax in RFC4419 (there is another simple Rsax-shax switching algorithm). This paper takes

I. List of data encryption/coding algorithms   common cryptographic or coding algorithms used to ensure security are as follows:  1, common key algorithm   key algorithm is used to encrypt sensitive data, digest, signature and other information,

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 number of on-demand computers has important applications in many fields, such as Monte Carlo simulation, cryptography, and network security. The random number quality is directly related to the reliability and security of the network security

Android Development, will inevitably encounter the need to decrypt some of the data content to the local file, or transmission over the network to other servers and devices, but not the use of encryption is absolutely safe, if the encryption

Message Digest also known as data fingerprint, mainly used for data integrity check, such as when you download a jar package in Apache, in addition to the download list will provide a download link, but also provide the MD5 summary value, when you

Previous wordsCryptographic modules provide a way to encapsulate security credentials during an HTTP or HTTPS connection. It also provides encapsulation of OpenSSL's hash, HMAC, encryption (cipher), decryption (decipher), signature (sign), and

Come from:http://blog.csdn.net/lonelyroamer/article/details/7630594 I. Overview The MAC algorithm combines the advantages of the MD5 and Sha algorithms and joins the key support, which is a more secure message digest algorithm. MAC (Message

Topic One: Why is HTTPS safe1. Why is HTTP not secure?The HTTP protocol belongs to the plaintext transmission protocol, the interaction process and data transmission are not encrypted, the communication parties have not carried out any
