goKryptor is a small and portable cryptographic tool for encrypting and decrypting files. This tool supports XOR and AES-CTR (Advanced Encryption Standard in Counter Mode) encryption algorithm. The '--start-offset' or '--end-offset' flag allows you to encrypt/decrypt a portion of file or the whole of it.
Usage: goKryptor -a aes -k STRING -c 1024 <command> <file or folder>

Flags:
-h, --help Show context-sensitive help.
-a, --algo=STRING Algorithm used to encrypt or decrypt data (xor,aes). The none value simulate encryption/decryption by simply renaming the files with the file extension specified.
-k, --key=STRING Key used to encrypt or decrypt data.
-c, --chunk-size=1024 Chunk size used to encrypt or decrypt data (default: 1024 bytes).
-o, --out-path=STRING Specify the output path to write encrypted data. A specific file can be specified or a folder path (must end with '/' or '\\').
--start-offset=0 Encrypt/Decrypt data FROM a specific offset (by using negative number, the encryption/decryption starts from the end of file).
--end-offset=0 Encrypt/Decrypt data TO a specific offset (by using negative number, the encryption/decryption starts from the end of file).
-x, --file-ext=STRING Specify the file extension to be used for encrypting/decrypting files (default: .enc or .plain).
-e, --entropy Display and calculate the Shannon Entropy of the file.
-v, --version Print version information and quit.
Commands:
encrypt --key=STRING --chunk-size=1024 <path>
Encrypt file or all items in folder.
decrypt --key=STRING --chunk-size=1024 <path>
Decrypt file or all items in folder.
