axxd

An axx file decryption tool.

This tool can decrypt AxCrypt-encrypted files. I made this because I needed a simple native tool to decrypt axx files on Linux and I didn't want to use WINE.

Usage

The newest standalone version can be downladed from GitHub Releases or build from sources using cargo build --release.

axxd 0.1.0
Axxd - an [axx] file [d]ecryptor

USAGE:
    axxd [FLAGS] [OPTIONS]

FLAGS:
    -h, --help            Prints help information
    -n, --no-overwrite    Abort when target file already exists
    -o, --overwrite       Overwrite target file if exists
    -V, --version         Prints version information

OPTIONS:
    -f, --file <FILE>          Input file path
    -p, --passphrase <PASS>    Encryption passphrase

If you don't specify -f or -p options, you will be asked for the missing parameters.

Example:

$ ./axxd -p secret.axx
Enter passphrase: 
test
Decrypting secret.axx...
File successfully decrypted. Saving into "secret.txt".

The app will ask you if a target file already exists. To decrypt files in fully non-interactive mode, use -o or -n.

$ ./axxd -f secret.axx
Enter passphrase: 
test
Decrypting secret.axx...
File successfully decrypted. Saving into "secret.txt".
WARNING: File already exits. Proceed? [y/n]
n
Aborting.

$ ./axxd -f secret.axx -p test -n
Decrypting secret.axx...
File successfully decrypted. Saving into "secret.txt".
WARNING: File already exits. Aborting.

Using the API

You can simply decrypt a file using a decrypt_file<P: AsRef<Path>>(path: P, passphrase: &str) function. It reads the file and then tries to decrypt it using a given passphrase. Returns decrypted content as result.

    match decrypt_file(&source_file, &pass) {
        Ok(content) => save_file(content),
        Err(e) => {
            println!("Cannot decrypt file.");
            display_error_and_quit(e);
        }
    }

You can also use decrypt(data: &EncryptedContent, passphrase: &str) to decrypt raw content. To parse raw bytes into EncryptedContent, use the parse function

    let data = EncryptedContent::parse(&input);
    decrypt(&data, passphrase)
