This article mainly introduces the computer 7z refers to what format, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

7z is an efficient compression format, which can use a variety of compression algorithms for data compression, with a very high compression ratio. The 7z format supports 256-bit key AES algorithm encryption, and the key is obtained by SHA-256hash algorithm with the secret code provided by the user.

7z is a mainstream and efficient compression format with a very high compression ratio. In computer science, 7z is a file format that can use a variety of compression algorithms for data compression. This format was originally implemented and adopted by 7-Zip, but the file format is public, and the 7-Zip software itself is open source under the GNU wide General Public license (GNU LGPL) agreement. The latest version of the LZMA SDK is V9.34. The MIME type of 7z format is application/x-7z-compressed.

Generally speaking, the 7z format of 7-Zip can be 30-70% smaller than the compressed file using zip format.

And the zip format created using 7-Zip is 2-10% smaller than that created by most other compression software.

Main features:

Open source and modular component architecture (allows the use of any compression, conversion, or encryption algorithm)

Highest compression ratio

Powerful AES-256 encryption

Algorithms that can be changed and configured for compression

Support for very large files (up to 16EB)

Unicode filename support

Support solid compression, allowing files of inner classes to be compressed in a stream, so that similar content can be effectively compressed

Supports header compression of files

Support for multithreaded compression

The 7z format supports 256-bit key AES algorithm encryption. The key is obtained by the SHA-256hash algorithm of the secret code provided by the user (using a large number of iterations to make the brute force decoding of the secret code more difficult)

Thank you for reading this article carefully. I hope the article "what format 7z in the computer refers to" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
