Automatic Keys


One Time Pad encryption never became popular because of its difficult key management where every file needs to be encrypted with an equally sized unique key file.

FinalCrypt's Automatic Keys enable multi-file OTP Encryption, which is not possible with Manual OTP Key creation for every file to encrypt.

One key encrypting multiple files (key re-usage) breaks the One Time Pad rule making encrypted files vulnerable to exploits. FinalCrypt's Automatic Keys are unique.

One Time Pad Key Demands


One Time Pad Encryption keys have the following requirements:

1. Key files have to be kept completely secret at all times
2. Key files are at least equal in size to the file it encrypts
3. Keys are created with a True Random Number Generator
4. Key files may only be used once to encrypt a file

The above rules make One Time Pad encryption unbreakable.

Many Governments worldwide have used and still use One Time Pad Encryption when maximum secrecy is required.

Key Directory

Your Key Directory stores your automatically created keys
Select your Key Directory on a external (USB) flash drive
Manual keys are still supported but strongly discouraged


FinalCrypt automatically creates Keys in your Key Directory
Key files are never reused to comply to One Time Pad rules
Key File Path = Selected Key Dir + Encrypted File Full Path


FinalCrypt automatically finds key files in your Key Directory
Files are decryptable on matching key (and correct password)
