SFEDXOR 0.0.2 - Single File Encryption & Decryption - Random Keys or Manual Keys - Hackers - Feb 20, 2024

SFEDXOR
Version 0.0.2
Single File Encryption & Decryption: XOR

Encrypt Any Filetype
Decrypt Your Encrypted File
Single String Key / "Password"
Use Random Encryption Key (automatically matches byte size of file you are encrypting)
or Supply Your Own Key
Output Key to File (for use later)
Use File for Key Input (instead of string)

ENCRYPT EXAMPLES

Code
./SFEDXOR -i <inputfile> -o <outputfile> -m encrypt [-k <keyfile>] [-ko <keyoutputfile>] [-ks <keystring>]
- <inputfile>: Path to the input file to be encrypted.
- <outputfile>: Path to save the encrypted output file.
- -m encrypt: Mode for encryption.
- -k <keyfile>: Optional. Path to a file containing the encryption key. If not provided, a key will be auto-generated.
- -ko <keyoutputfile>: Optional. Path to save the encryption key to a file.
- -ks <keystring>: Optional. Inline key string to use for encryption.

Encrypt with auto-generated key:
Code
./SFEDXOR -i input.txt -o encrypted.txt -m encrypt

Encrypt with specified key file and save key to another file:
Code
./SFEDXOR -i input.txt -o encrypted.txt -m encrypt -k key.txt -ko key_saved.txt

Encrypt with inline key string:
Code
./SFEDXOR -i input.txt -o encrypted.txt -m encrypt -ks mysecretpassword


DECRYPT EXAMPLES

Code
./SFEDXOR -i <inputfile> -o <outputfile> -m decrypt [-k <keyfile>] [-ks <keystring>]
- <inputfile>: Path to the encrypted input file.
- <outputfile>: Path to save the decrypted output file.
- -m decrypt: Mode for decryption.
- -k <keyfile>: Optional. Path to a file containing the decryption key.
- -ks <keystring>: Optional. Inline key string to use for decryption.

Decrypt with specified key file:
Code
./SFEDXOR -i encrypted.txt -o decrypted.txt -m decrypt -k key.txt

Decrypt with inline key string:
Code
./SFEDXOR -i encrypted.txt -o decrypted.txt -m decrypt -ks mysecretpassword

The original SFEDXOR 0.0.1 does not include input/output key files, only inline string keys, and did not have random encryption key generation:

Disclaimer:
This is not a crypter, it is a single file encryption & decryption tool. You can use it to lock down your own files for security, to decrypt later. You can also use the final program in scripts that access command line for bulk encryption/decryption. The program does not have built in folder support, only single files. This works with any type of file, but you must make sure to keep the same file extension on the output when you decrypt. The file extension used for the encrypted file doesn't matter as long as it is decrypted into the final, correct format.

XOR is two-way symmetrical encryption. If you use a key that is shorter than the file you are encrypting/decrypting, you can expect partially exposed data.

consider using std::random_device along with std::mt19937 for better random number generation instead of srand(time(nullptr))

[Image: ADdv3e1.png?ex=65e2591e&is=65cfe41e&hm=b...height=417]~ std::mt19937
[Image: X8VMazK.png?ex=65e25926&is=65cfe426&hm=8...height=417]~ srand(time(nullptr))


In the XorEncryptDecrypt function, replace direct file reading/writing with buffered input/output streams to handle files efficiently in chunks.
( For dealing with massive files )


Cool project though, hoping to see more updates in the future.

Very nice Hackers !!! <3 💯
My bro Klonopin master of the art!We posted together by the way hahaha !

This is smart for thinking about file buffering / chunks.
I will look into that if I release a 0.0.3 as well as making sure rand is more reliably random.
