Want to "encrypt" your stuff with a totally not secure algorithm? You're in luck!
Encrypt:
echo "this is not secure" | ./crappycrypto.sh -e
Decrypt:
cat encrypted.txt | ./crappycrypto.sh -d
It should be obvious by now: do NOT not use this for "encrypting" anything you actually care about being private. This is for fun only.
But I suppose, security through obscurity?
