LockBox - Open-Source and Simple Encyrption

Design

What It Does

LockBox is a symmetric-encryption algorithm designed to be run as a standalone program- E.g., in cases of local file encryption. However, under the license of LockBox, all users are allowed to customize it to their needs.

How It Works

LockBox works by using a custom, crytographically-secure random number generator to generate a symmetric key, based on values such as time since Unix epoch, the bit values of random RAM addresses, and more.

This varies HEAVILY from former versions of LockBox, which used a unique method of random image generation as a way or storing and sharing keys- Which was both stupid and smart in equal rites.

To-Do List

• [X] PrepFile()
  • Small misnomer- Does not prep the file itself, instead gives a block size that the file will be broken into in order to encrypt it. This is almost entirely useless on modern systems, only really existing to support memory-limited and legacy systems.
• [ ] Enc/Dec
  • The actual encryption and decryption code. This is going to be the hardest part, and will therefore take the longest.
• [ ] Padder()
  • Uses either an ANSI-X.923 or a PKCS#7-style method of padding.
• [ ] Validate()
  • Simple validation script. Just decrypts the data and compares the results. Simple, quick, and effective.
