It supports the following encryption methods:\n\n- **Shift Cipher (Caesar Cipher)**: A substitution cipher that shifts each character by a fixed number of positions in the alphabet.\n- **Affine Cipher**: A cipher that combines multiplication and addition to transform characters. Requires two keys (a multiplier and an offset).\n- **Substitution Cipher**: A cipher where each character is replaced based on a permutation of the alphabet.\n- **Hill Cipher (2x2)**: A cipher based on linear algebra, using a 2x2 key matrix for encryption.\n- **Transposition Cipher**: A cipher that rearranges the characters of the text based on a key.\n- **Vigenere Cipher**: A cipher that applies multiple Caesar ciphers based on a repeating key.\n\nEach command allows the user to specify input text, keys, and alphabet files, as well as the output file and mode (encryption or decryption).\n\n---\n\n## Run\n\n1. Clone the repository:\n\n   ```bash\n   git clone git@github.com:LLIEPJIOK/crypto.git\n   ```\n\n2. Navigate to the project folder:\n\n   ```bash\n   cd crypto\n   ```\n\n3. Run the program:\n\n   ```bash\n   go run main.go\n   ```\n\n---\n\n## General Command Format\n\n```bash\ncrypto \u003ccommand\u003e -t \u003ctext file\u003e -k \u003ckey file\u003e -a \u003calphabet file\u003e -o \u003coutput file\u003e [-d]\n```","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flliepjiok%2Fcrypto","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flliepjiok%2Fcrypto","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flliepjiok%2Fcrypto/lists"}
