v1pad is a command-line tool that encrypts and decrypts files using one-time-pad encryption. v1pad uses a virtual pad, meaning that the one-time pad is generated dynamically based on user input instead of being stored in a file. The name v1pad is an abbreviation for Virtual One-Time Pad.

...The code is shared here for posterity (future folk) in the guise that it may help others also on the path to cryptography. This code demo uses a 256bit rolling hash table (8x8bytes) at its heart to mix together pre-defined parameters in a way that allows the cipher to produce encoded output that is locked to a key of arbitrary length without padding. Based upon some random data points the cipher produces encoded output that is non-deterministic in nature, the same key and message will never produce the same output each time it's run. ...

...If the -p passphrase argument is given a specific table is generated and is repeatable each time the same passphrase is given.
