A program that helps you encrypt / decrypt files with:

• Shifting bits
• SHA-256 checksum
• SHA-512 checksum
• Flip bits
• Reverse bytes
• Reverse bits
• Overwrite with nulls

Shifting: enctools -shift <number_of_shifts> <input_file> <output_file> or enctools -shift <number_of_shifts> <input_file>. If you want to encrypt by shift x times, you need to decrypt by shifting -x times.
SHA-256 checksum: enctools -sha256 <input_file> <output_file>
SHA-512 checksum: enctools -sha512 <input_file> <output_file>
Flip bits: enctools -flipbit <input_file> <output_file>. If you want to decrypt, just "encrypt" it one more time.
Reverse bits: enctools -revbit <input_file> <output_file>. If you want to decrypt, just "encrypt" it one more time.
Reverse bytes: enctools -revbyte <input_file> <output_file>. If you want to decrypt, just "encrypt" it one more time.
Nullify: enctools -null <input_file>.
Help: enctools -h.

When the output file is not provided, the output file is the input file.
The program is in testing, so there are a few exceptions that the program didn't catch. The program may won't work in some binary files (.exe, ...)

Thanks ChatGPT for corprating with me to make this program.
