-Obfuscate & Encrypt Text as White-Space

+**Warning**: The cryptography library Snow10 uses a poor way of generating keys from a password. I will fix this in the future, but it should be "good enough" if you use a highly random password. In general I recommend using PGP instead for the encryption portion for now.
