A Neovim plugin to encrypt and decrypt buffers with ccrypt.

ccrypt is like AES and is based on the Rijndael cypher, and uses a 256-bit block size:

• Project page: ccrypt

You must have ccrypt installed and it must be in your path.

Install the plugin with your package manager:

lazy.nvim:

{
    "fouladi/ccrypt-wrapper.nvim",
    config = function()
        require("ccrypt-wrapper").setup({})
    end,
}

After setup, the following commands will be automatically applied.

The commands :Encrypt and :Decrypt are defined to call ccrypt for encrypting and decrypting the buffer.

The commands :EncryptFile and :DecryptFile call ccrypt to encrypt and decrypting whole file.

Encrypts buffer content using ccrypt with a password.

Decrypts buffer content using ccrypt with a password.

Encrypts the currently open buffer file using ccrypt.

1. Prompts the user to enter and confirm an encryption password.
2. Checks if the buffer is named and non-empty.
3. Writes the buffer to disk.
4. Prompts for confirmation if the target file (<file>.cpt) already exists.
5. Uses ccrypt to encrypt the file, which automatically appends .cpt.
6. Deletes the original unencrypted file after successful encryption.
7. Opens the encrypted file in the current buffer.

Decrypts the currently open .cpt file using ccrypt.

1. Prompts the user to enter the decryption password.
2. Validates that the current file has a .cpt extension.
3. Writes the buffer to disk (to ensure content is current).
4. Uses ccrypt to decrypt the file in-place.
5. Automatically opens the decrypted file (with .cpt removed) in the buffer.

If you have not installed ccrypt, you will receive this error message when you call up the above functions:

Error: ccrypt is not installed.
