GunderCrypt is a command line-based text encrypting/ciphering program and library for java. This is a semi-advanced cipher class implementing pseudo-random shifting, combined with password protected letter shifts (GunderCrypt.java), it provide simple cryptography for any plain text messages. Messages are encrypted more securely the more words that are present. Passwords must be ONLY uppercase letters and spaces. No lowercase or numbers.

It is an Advanced text Ciphering tool and should be run as follows:
GunderCrypt.jar [mode] [text] [password]

Modes:
encode Turns a string into an encoded message.
e Same as encode.
decode Decodes a coded message.
d Same as decode.

text:
