Most of the modern archiving utilities support this format. You can also use it on Windows with installation of additional software. Tar is mostly used in Linux and it doesn’t support compression or encryption. Initially, it was used to combine and write data to sequential tape drives but was later standardized as a compression format.

7zip vs betterzip archive#

Tape Archive (Tar) is one of the oldest archive formats.

Below, we will evaluate each archive format using three parameters – whether it supports compression and encryption, which Operating System and software is available for its usage. There are various archive formats available. Note: There are several other encryption algorithms but the above-mentioned three are the most used ones. Blowfishīlowfish encryption algorithm encrypts the archives with a 64-bit block size and a variable key length of 32 to 448-bits.

AES uses a symmetric key algorithm which means that a common key is used for encrypting and then decrypting the data. You can encrypt data using 128, 192 and 256 bits of encryption. AESĪdvanced Encryption Standard is an encryption algorithm used by the US agencies to secure sensitive data. The secret key is selected randomly from a 56 to 64-bit address space. Now let’s go through some of the popular encryption methods:ĭata Encryption Standard uses private secret keys to encrypt and decrypt data. Since Deflate does not contain implementations restricted by patents, it has become very popular and is widely used, especially in Linux. Deflateĭeflate is a popular data compression algorithm which uses a combination of LZ77 and Huffman coding algorithms to compress data (combining LZMA and PPM algorithms to produce more compression). Prediction by partial matching (PPM) is a statistical data compression method which works by using set of previous symbols in the uncompressed symbol stream to predict the next symbol in the stream. Burrows-Wheeler Transform Algorithm (BWT)īWT works by permuting a string of text in order and then compress them by replacing the repeating characters into symbols. It can also compress data that is not compressible with other compression algorithms. It supports multi-threaded compression and decompression of data.

LZMA2 is a container which contains both the uncompressed and LZMA-compressed data. LZMA uses a dictionary compression algorithm which makes use of complex data structures to encode one bit at a time. Lempel–Ziv–Markov (LZMA) chain algorithm is a lossless data compression algorithm. Compression algorithm is the method used by the archive to compress the files and make the overall file size smaller.
