 Introducing **Archiver 3.1** - a cross-platform, multi-format archive utility and Go library. A powerful and flexible library meets an elegant CLI in this generic replacement for several platform-specific or format-specific archive utilities.

 **Security note: This package does NOT attempt to mitigate zip-slip attacks.** It is [extremely difficult](https:/rubyzip/rubyzip/pull/376) [to do properly](https:/mholt/archiver/pull/65#issuecomment-395988244) and [seemingly impossible to mitigate effectively across platforms](https:/golang/go/issues/20126). [Attempted fixes have broken processing of legitimate files in production](https:/mholt/archiver/pull/70#issuecomment-423267320), rendering the program unusable. Our recommendation instead is to inspect the contents of an untrusted archive before extracting it (this package provides `Walkers`) and decide if you want to proceed with extraction.
