tinycrypt

Tiny library for encrypting files and byte streams.

Installation:

go get github.com/BitlyTwiser/tinychunk

Testing:

• Initially run go mod tidy to install necessary packages.
• One can test the module via utilizing the go test framework. go test tinycrypt_test.go -v

Usage:

• Example usage can be seen within the test file.
