go get github.com/richard-lyman/lithcrypt/
The result of encrypting some byte slice is a header followed by the encrypted content. The header contains the salt, N, r, p, key length, and iv - enough to decrypt the content if the password is provided.
- Run the installation command from above
- Place the following code in some file (we'll call ours 'main.go')
- From the same folder where you created your file ('main.go'), run the command
go run main.go(replacing 'main.go' with whatever name you gave your file)
package main

"encoding/base64"
