# Kryptera
[](https://www.nuget.org/packages/Kryptera)
[](https://www.nuget.org/packages/Kryptera.Tools)
[](https://codecov.io/gh/gowon/kryptera)
Kryptera is a .NET Core Tool to quickly encrypt and decrypt files using AEAD AES-256-GCM algorithm from [CryptHash.NET](https://github.com/alecgn/crypthash-net/), as well as an encryption key generator. Kryptera means "encrypt" in [Swedish](https://translate.google.com/?sl=sv&tl=en&text=kryptera&op=translate).
## Install
|Package|Stable|Preview|
|-|-|-|
|Kryptera|[](https://www.nuget.org/packages/Kryptera)|[](https://f.feedz.io/gowon/pre-release/packages/Kryptera/latest/download)|
|Kryptera.Tools|[](https://www.nuget.org/packages/Kryptera.Tools)|[](https://f.feedz.io/gowon/pre-release/packages/Kryptera.Tools/latest/download)|
The Kryptera library can be obtained by either locally cloning this git repository and building it or via NuGet/Feedz:
```shell
Install-Package Kryptera
```
or
```shell
dotnet add package Kryptera
```
The command-line tool for encrypting and decrypting files can be installed through the `dotnet` CLI:
```shell
dotnet install --global Kryptera.Tools
```
after which it is available for use in your shell as `kryptera`.
## Usage
You can use the `--help` option to get detailed information about the commands.
```shell
kryptera
Usage:
kryptera [options] [command]
Options:
-v, --verbosity Set output verbosity
--version Show version information
-?, -h, --help Show help and usage information
Commands:
encrypt Encrypt a file or directory using AES-256-GCM
decrypt Decrypt a file or directory using AES-256-GCM
generate Generate a new AES-256 key
```
### Create an encryption key
You can create a new encryption key using the following command:
```shell
> kryptera generate
tRKvyxIcQA6jV0eUoH/LA1QFlDSNUQRfzDJqU9CSvzM=
```
The output is sent directly to the console, and can be piped directly as input into other applications or scripts.
### Encrypt a file or directory
You can encrypt a file or directory using the following command:
```shell
kryptera encrypt --key
```
The filenames for the encrypted files will have `.aes` appended to them to make them easy to distinguish from the original files.
### Decrypt a file of directory
You can decrypt a file or directory using the following command:
```shell
kryptera decrypt --key
```
If the encrypted files have `.aes` extensions, then the filenames for the decrypted files with have this extension removed. If the encrypted file extensions are not `.aes`, then the filenames of the decrypted files with have `-decrypted` appended to the name right before the extension.
