base64 encryption

Analysis of four basic encryption algorithms in Java   Simple java encryption algorithms include: 1. BASE64 Base64 is one of the most common encoding methods used to transmit 8-bit code on the network. For details, refer to RFC2045 ~ RFC2049,

Several encryption methods common to iOSThe normal encryption method is to encrypt the password and save it to user preferences.The keychain is saved in clear text, but does not know the exact location of the storage1,base64 encryption Base64 coding

First, the Basic authentication of http:During the communication of the HTTP protocol, the HTTP protocol defines the Basic authentication process to allow the HTTP server to authenticate the user to the Web browser, and when a client makes data

Some basic concepts involved in mail development 1.1, mail server and e-mail To provide e-mail functionality on the Internet, you must have a dedicated e-mail server. For example, the Internet is now a lot of providers of mail services: Sina, Sohu,

I've never written a document before, and I've decided to start sorting the code from now on. It's easy to look through it later. Because now do the project data need to encrypt, so that they see in the database is ciphertext, so first through the

I. Scenario Description: Title How effective, the smallest amount of existing code intrusion to achieve the client-server data exchange encryption? Two. Explore: 1. Demand Analysis The WEBAPI server has the following interfaces: public class

SIP is similar to HTTP protocol. The authentication mode is also the same. The HTTP protocol (RFC 2616) stipulates that the base mode and digest mode can be used ). RFC 2617 specifies two authentication modes. RFC 1321 is the MD5 standard. Digest is

Ios 32-bit and 16-bit MD5 EncryptionDuring IOS development, we usually adopt encryption methods to ensure data security. Common encryption methods include Base64 encryption and MD5 encryption. Base64 encryption is reversible. Currently, MD5
