Usage: Obfuscator mode key
mode either + or -; eg, a file encrypted with - and then re-encrypted
with - will be decrypted by running + and +.
key the secret stream cipher private-key
Example:
Obfuscator + "12345" < secret > secret_encrypted
Obfuscator - "12345" < secret_encrypted > secret_decrypted
The encryption process uses an algorithm that the author made
himself. It turns out that it's a stream cipher. The length of the
key is linearly related to how many bits of encryption. The bits of
the key generate a pseudorandom keysteam. The author is not an
expert, and it is possible that this is insecure.
