- DEFLATE is one of the most basic and widespread algorithms out there
- PPMD is an improved version of PPM algorithm orignally developed in 1984
- Bzip2 - Burrows-Wheeler algorithm that also employs Huffman coding. It is one of the most powerful compression algorithms to date
- LZMA is a modified version of LZ77 (similar to DEFALTE) which employs entropy coding by Markov chains and Patricia trees
7-Zip may preprocess 32-bit x86 executable files with either BCJ or BCJ2 to achieve greater compression ratios.
7-Zip supports data encryption by 256-bit AES algorithm. The encryption key is also strengthened by applying SHA-256 hashing
