zlib-tiny

A Clojure library designed to cover basic needs of packing|unpacking exchange messages, storable chunks etc. And to check their consistency.

Usage

Add the following to your Leiningen’s project.clj:

[net.tbt-post/zlib-tiny "0.3.1"]

Compress

ZLib

;; ZLib Example

(bytes->str
 (force-byte-array
  (inflate
   (deflate
    (str->bytes "test it!")))))

(-> "test it!"
    str->bytes
    deflate
    inflate
    force-byte-array
    bytes->str)

GZip

;; GZip Example

(bytes->str
 (gunzip
  (gzip
   (str->bytes "test it!"))))

(-> "test it!"
    str->bytes
    gzip
    gunzip
    bytes->str)

Checksums

CRC

;; CRC32 example
(crc32 (.getBytes "123456789"))
=> 3421780262

;; CRC64 example
(crc64 (.getBytes "123456789"))
=> -7395533204333446662
