API/Commands

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

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:

<major>.<minor>.<patch>

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
