This is an AWS Lambda layer containing the statically linked 7za binary utility from the p7zip package. p7zip is a Unix port of the 7-Zip file archiver. It supports high compression ratio in the 7z format, as well as many other compression and archive formats (e.g. zip, tar, gzip, bzip2). It also supports strong AES-256 encryption in 7z and zip formats. You can use this layer in your Lambda function to compress/uncompress 7z/zip archive files, e.g. using the node-7z wrapper for Node.js.

As we are no longer using this Lambda layer in our own projects, this repo has been archived. (No pun intended.) To generate Zip archives using strong AES-256 encryption, you can use the archiver package with the archiver-zip-encrypted plugin instead.

You can use the published layer using the following ARNs (based on region):

Alternatively, if you want to publish the layer yourself, edit the provided Makefile to set the AWS region to publish to, then run make publish.

The 7za binary can be found in /opt/bin/7za inside your Lambda container.

This package includes p7zip 16.02, pulished on 2016-07-14. For more information, check out https://sourceforge.net/projects/p7zip/files/p7zip/.
