All the software of all modern computers is written on the basis of the idea of coding information. All processes on the Internet are also associated with the encoding process; any digital information is a binary code. Encoding is also successfully used in the process of protecting information, individual files on the Internet.
Necessary
- - Programming skills;
- - a program like Crypditor.
Instructions
Step 1
Storing unencrypted information on the server can lead to unwanted leakage of information, in particular - keys to the database or, for example, some important document. Therefore, it is better to encrypt all files in advance, i.e. encode. There are many programs that can help you protect the data you need, but many of them are either unreliable or paid. Many data can be protected using standard PHP tools. The base function base64_encode () is suitable for this. For reverse decoding, respectively, base64_decode () is used. There are also algorithms md5 () and sha1 (), but they are practically indecipherable. PHP also widely uses JSON encoding. It allows you to encrypt information in a specific data array and has the form json_encode ($ array). For decoding, respectively, json_decode ($ array). To encode information transmitted from forms, you can use the crypt () method. It encrypts information in one direction. The advantage of this feature is that it allows you to define your own rules.
Step 2
Using Java Script, you can easily encode some image data. There is a javascript: imageData function for this. There is also a kind of URI algorithm that can assign its own identifier to each element. The URI has the syntax: "URI = URL + URN URL =: // URN =".
Step 3
To encode passwords from any resources, or even from a computer, you can use the Crypditor program, which uses the AES encryption algorithm. Moreover, this program allows you to check the strength of the passwords used before they are encrypted.
