# Let's Decrypt
Let's Decrypt is a powerful decryption tool supporting multiple encryption standards. It allows users to decrypt messages and files using various cryptographic algorithms and efficiently manage decrypted outputs.
## Supported Encryption Methods
Let's Decrypt supports the following encryption methods:
- **Fernet** (Symmetric encryption ensuring message integrity)
- **AES-128** (Advanced Encryption Standard with a 128-bit key)
- **AES-192** (Advanced Encryption Standard with a 192-bit key)
- **AES-256** (Advanced Encryption Standard with a 256-bit key)
- **ChaCha20** (A high-performance stream cipher alternative to AES)
## Installation
You can install Let's Decrypt using one of the following methods:
### Install via pip
For Python users, install Let's Decrypt using `pip`:
```sh
pip install letsdecrypt --break-system-packages
```
### Install via Snap
For Linux users, install Let's Decrypt using Snap:
```sh
snap install letsdecrypt
```
## Usage
Let's Decrypt can be used for encryption and decryption of text messages and files.
### Basic Command Syntax
```sh
letsdecrypt.py [-h] [--fernet] [--aes-128] [--aes-192] [--aes-256] [--chacha20] [--key KEY]
[--key-file KEY_FILE] [--go-decrypt GO_DECRYPT] [--go-decrypt-file GO_DECRYPT_FILE]
[--save-decrypt SAVE_DECRYPT] [--save-output SAVE_OUTPUT]
[--save-decrypt-random SAVE_DECRYPT_RANDOM] [--save-output-random SAVE_OUTPUT_RANDOM]
[--verbose] [--silence]
```
### Decryption Methods
- `--fernet` → Use the **Fernet** encryption standard for decryption.
- `--aes-128` → Decrypt using **AES-128** encryption.
- `--aes-192` → Decrypt using **AES-192** encryption.
- `--aes-256` → Decrypt using **AES-256** encryption.
- `--chacha20` → Decrypt using **ChaCha20** encryption.
### Key Input Options
- `--key KEY` → Provide the decryption key as direct input.
- `--key-file KEY_FILE` → Provide a file containing the decryption key.
### Decryption Options
- `--go-decrypt GO_DECRYPT` → Decrypt a message directly from input.
- `--go-decrypt-file GO_DECRYPT_FILE` → Specify a file containing an encrypted message for decryption.
### Output Options
- `--save-decrypt SAVE_DECRYPT` → Save the decrypted message to a specified file.
- `--save-output SAVE_OUTPUT` → Save the entire program output to a file.
- `--save-decrypt-random SAVE_DECRYPT_RANDOM` → Save the decrypted message to a randomly named file.
- `--save-output-random SAVE_OUTPUT_RANDOM` → Save the complete program output to a randomly named file.
### Additional Settings
- `--verbose` → Enable verbose mode for detailed output.
- `--silence` → Display only the decrypted message without logs.
### Example Usage
## Security Considerations
- Always store your encryption keys securely.
- Do not use weak passwords for encryption.
- Use **Fernet** for an easy and secure encryption method.
