fxor is a tool that you can use to encrypt/decrypt IN_FILE content with KEY_FILE content using XOR operation, and output to:
- The file OUT_FILE.
- STDOUT if OUT_FILE not defined.
fxor can be used as OTP (One-Time Pad) tool.
IN_FILE: Input file name, Witch will processed.
KEY_FILE: Key file name, Usually random bytes file.
OUT_FILE: Output file name.
-r:
Overwrite (destroy contents) OUT_FILE then output
-s:
Start output from OUT_FILE beginning and replace bytes,
Perfect to encrypt/decrypt IN_FILE and output to IN_FILE!
Output to OUT_FILE (overwrite if exist):
fxor IN_FILE KEY_FILE OUT_FILE -r
Output to OUT_FILE and replace byte by byte from beginning:
fxor IN_FILE KEY_FILE OUT_FILE -s
Output to STDOUT:
fxor IN_FILE KEY_FILE
fxor follows the semantic versioning scheme.
