Using gzip and aespipe $ cat clear_text | gzip | aespipe > clear_text gz aes #Compress Encrypt $ cat clear_text gz aes | aespipe -d | gunzip > clear_text #Decrypt Decompress aespipe is what it sounds like, a program that takes input on stdin and outputs aes encrypted data on stdout
What is the maximum compression ratio of gzip? - Super User It very much depends on the data being compressed A quick test with a 1Gb file full of zeros using a standard version of gzip (with default options or specifying -9) gives a compressed size of ~1018Kb, so your 10Kb file could potentially expand into ~10Mbytes
How to gzip multiple files into one gz file? - Super User Quoth the gzip manpage: If you wish to create a single archive file with multiple members so that members can later be extracted independently, use an archiver such as tar or zip GNU tar supports the -z option to invoke gzip transparently gzip is designed as a complement to tar, not as a replacement
Between xz, gzip, and bzip2, which compression algorithim is the most . . . The fastest algorithm are by far lzop and lz4 which can produce a compression level not very far from gzip in 1 3 seconds while gzip took 8 1 second The compression ratio is 2 8 for lz4 and 3 7 for gzip Here are a few results I extracted from this article : Gzip : 8 1s @ 3 7 lz4 : 1 3s @ 2 8 xz : 32 2s @ 5 43 xz -e : 6m40 @ 7 063 xz
gzip - How do I gunzip a directory? - Super User gzip is a stream compressor - it doesn't really look at the contents of what you are compressing beyond what it needs to to in order to make it smaller so it has no concept of directories Just as a side note, I find bzip2 to do a much better job of compression than gzip - albeit slower
