# cryptr
#### A simple shell utility for encrypting and decrypting files using OpenSSL.
## Installation
```
git clone https://github.com/nodesocket/cryptr.git
ln -s "$PWD"/cryptr/cryptr.bash /usr/local/bin/cryptr
```
### Bash tab completion
Add `tools/cryptr-bash-completion.bash` to your tab completion file directory.
## API/Commands
### encrypt
> encrypt \ - Encryptes file with OpenSSL AES-256 cipher block chaining. Writes an encrypted file out *(ciphertext)* appending `.aes` extension.
```
➜ cryptr encrypt ./secret-file
enter aes-256-cbc encryption password:
Verifying - enter aes-256-cbc encryption password:
```
```
➜ ls -alh
-rw-r--r-- 1 user group 1.0G Oct 1 13:33 secret-file
-rw-r--r-- 1 user group 1.0G Oct 1 13:34 secret-file.aes
```
You may optionally define the password to use when encrypting using the `CRYPTR_PASSWORD` environment variable. This enables non-interactive/batch operations.
```
➜ CRYPTR_PASSWORD=A1EO7S9SsQYcPChOr47n cryptr encrypt ./secret-file
```
### decrypt
> decrypt \ - Decrypt encrypted file using OpenSSL AES-256 cipher block chaining. Writes a decrypted file out *(plaintext)* removing `.aes` extension.
```
➜ ls -alh
-rw-r--r-- 1 user group 1.0G Oct 1 13:34 secret-file.aes
```
```
➜ cryptr decrypt ./secret-file.aes
enter aes-256-cbc decryption password:
```
```
➜ ls -alh
-rw-r--r-- 1 user group 1.0G Oct 1 13:35 secret-file
-rw-r--r-- 1 user group 1.0G Oct 1 13:34 secret-file.aes
```
You may optionally define the password to use when decrypting using the `CRYPTR_PASSWORD` environment variable. This enables non-interactive/batch operations.
```
➜ CRYPTR_PASSWORD=A1EO7S9SsQYcPChOr47n cryptr decrypt ./secret-file.aes
```

## Versioning
For transparency and insight into the release cycle, and for striving to maintain backward compatibility, cryptr will be maintained under the semantic versioning guidelines.
Releases will be numbered with the follow format:
`..`
And constructed with the following guidelines:
+ Breaking backward compatibility bumps the major (and resets the minor and patch)
+ New additions without breaking backward compatibility bumps the minor (and resets the patch)
+ Bug fixes and misc changes bumps the patch
