rscrypt (scryptenc-cli) is a command-line utility for encrypt and decrypt files using the scrypt encrypted data format.

This is a Rust implementation of scrypt(1).

cargo install scryptenc-cli

If you want to enable optimizations such as LTO, set them using environment variables.

The release page contains pre-built binaries for Linux, macOS and Windows.

Please see BUILD.adoc.

Encrypt a file:

rscrypt enc data.txt data.txt.scrypt

Decrypt a file:

rscrypt dec data.txt.scrypt data.txt

Output as a human-readable string:

rscrypt info data.txt.scrypt

Output:

Parameters used: N = 1024; r = 8; p = 1;
    Decrypting this file requires at least 1 MiB of memory.

Output as JSON:

rscrypt info -j data.txt.scrypt | jq

Output:

{
  "N": 1024,
  "r": 8,
  "p": 1
}

completion subcommand generates shell completions to standard output.

The following shells are supported:

• bash
• elvish
• fish
• nushell
• powershell
• zsh

Example:

rscrypt completion bash > rscrypt.bash

Please see the following:

• rscrypt(1)
• rscrypt-enc(1)
• rscrypt-dec(1)
• rscrypt-info(1)
