Cryptr is a simple shell utility for encrypting and decryption files using OpenSSL.
Installation
git clone https://github.com/nodesocket/cryptr.git
ln -s “$PWD”/cryptr/cryptr.bash /usr/local/bin/cryptr
Add tools/cryptr-bash-completion.bash
to your tab completion file directory.
Encrypt
encrypt <file> – 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 <file.aes> – 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
