With the current world situation after the 9-11 terrorist attacks, your freedoms and privacy are under attack as never before by governments around the world, all in the name of "safety". The Fourth Amendment to the Constitution of the United States, in regards to e-mail and the Internet, is being thrown out the window. Protect your right to electronic privacy with Top Secret Crypto, the most powerful data and e-mail encryption program in the world. Do it now before it is too late and encryption programs are made illegal worldwide.

Top Secret Crypto (TSC) vs. PGP:

Maximum RSA Key Size: PGP: 2,048 bits TSC: 8,192 bits Maximum Conventional Key Size: PGP: 128 bits TSC: 5,093 bits - Method 1 Maximum Conventional Key Size using a One Time Pad Key File: PGP: N/A TSC: 20,261 bits - Method 2 Mximum Key Size Using a True One Time Pad File: PGP: N/A TSC: Same size as file or e-mail message - Method 3

TAN$TAAFL Software Company announces the release of Top Secret Crypto v1.10 which includes the following new features (Writing, sending, receiving, and reading encrypted e-mail messages just got a whole lot easier):

(1) - Import and export Public Keys through the clipboard in radix-64 text format.

(2) - Encrypt and decrypt portions of documents, or whole documents, through the clipboard.

(3) - Write e-mail messages using a Rich Text Edit Box, encrypt the message into a Top Secret Crypto Encrypted Message, and send it via your MAPI enabled e-mail program. Include file attachments and request a read receipt.

(4) - View the contents of your e-mail inbox, read all messages in text format, decrypt messages that are encrypted, and view the decrypted message in a Rich Text Edit Box in its original format. Reply to, or forward, any message.

(5) - View and manage the contents of your Address Book.

(6) - Send a regular e-mail message using your default e-mail program.

(7) - Select a file to attach to a regular e-mail message using your default e-mail program.

Note: Items 4 thru 7 requires that your default e-mail program support the Simple MAPI (Messaging Application Programming Interface) Protocol, which is used by e-mail programs such as Outlook, Outlook Express, or Eudora. AOL 4.0 and 5.0 do not support this protocol.

Top Secret Crypto is also the only encryption program that lets you create and use True One Time Pad Files for use in encrypting files. A True One Time Pad File provides one byte of random data for every byte in the file you are encrypting. The encryption key is therefore as long as the file you are encrypting. This constitutes a one-time pad encryption system that is unbreakable in theory and practice. Privacy maintained by mathematical law is now a reality.

Using removable media drives that support disk sizes up to 1, 2, 10, or even 20 gigabytes of random data; you can now create your own one-time pads to encrypt files with. Using a new, extremely fast algorithm to generate random data, a 1 gigabyte True One Time Pad File can be created in under 7 minutes on a 400 MHz Pentium II computer (22+ hours on an unregistered version using the original algorithm to generate random data).

Top Secret crypto utilizes RSA Public Key cryptography with key sizes ranging from 480 to 8,192 bits. It's conventional encryption algorithm, used by Methods 1 and 2, strings together 4, 8, 16, 32, 64, or 256 pseudo random number generators to provide extremely large key sizes. This is a stream cipher whose output is considered a pseudo one-time pad. Method 3, which encrypts with a True One Time Pad File, does not use any pseudo random number generators. Each byte in the file is encrypted against one byte of random data in a True One Time Pad File.

Top Secret Crypto provides three methods to encrypt your files and e-mail messages with, each with its own advantages and disadvantages.

Method 1 ======== A randomly produced session key for the conventional encryption algorithm is encrypted within a RSA Encrypted Integer. Depending on the size of the smallest RSA Key used, Top Secret Crypto will seed 4, 8, 16, 32, or 64 random number generators, which require 325-353, 613-669, 1189-1301, 2341-2565, or 4645-5093 random bits as the key. As long as the NSA cannot break the RSA Public Key Encryption System, these key sizes should be sufficient. I recommend a public key size of at least 4,096 bits. If you have a fast computer, use 8,192 bits. This should ensure adequate security for the foreseeable future.

The advantages of using a randomly produced session key encrypted within a RSA Encrypted Integer are (1) you can send an encrypted file to one or multiple recipients at the same time and (2) no extra material, such as a True One Time Pad File or One Time Pad Key File, is required to be exchanged between the sender and recipient.

The only disadvantage is if someone ever figures out a fast method of factoring large integers into their prime components. The key to the conventional encryption algorithm can then be extracted from the RSA Encrypted Integer and your file can be decrypted.

Method 2 ======== A One Time Pad Key File is used to seed 256 pseudo random number generators for the conventional encryption algorithm. This method provides a key space of between 18,469 to 20,261 bits for the conventional encryption algorithm. It is impossible for anyone to ever duplicate a key space of this size. I consider this method 100% secure.

The one advantage to using a One Time Pad Key File is its security. No one can decrypt a file encrypted with a One Time Pad Key File unless they steal a copy of the One Time Pad Key File.

The disadvantages are (1) you can only send an encrypted file to one recipient at a time, and (2) the sender and recipient must have a secure method of exchanging One Time Pad Key Files.

Method 3 ======== A True One Time Pad File is used to encrypt your file with. This method provides one byte of random data for each byte in the file you are encrypting. The key space is just as long as the file. There are no pseudo random number generators used, just random data. This is 100% secure and cannot be broken in theory or practice.

The one advantage to using a True One Time Pad File is its security. No one can decrypt a file encrypted with a True One Time Pad File unless they steal a copy of the True One Time Pad File.

The disadvantages are (1) you can only send an encrypted file to one recipient at a time, and (2) the sender and recipient must have a secure method of exchanging True One Time Pad Files.

Top Secret Crypto is particularly suited to businesses, (i.e. auditors, newspaper reporters, agents, buyers, troubleshooters, etc.) where the True One Time Pad Files, or One Time Pad Key Files, can be created in house for use by individuals when they go out into the field to conduct their work. They can then send back encrypted reports that are 100% secure from the preying eyes of any government's intelligence agencies, here or abroad.

Most individuals will find Method 1, a randomly produced session key encrypted within a RSA Encrypted Integer, more convenient. After exchanging Public Keys they can immediately start sending encrypted e-mail and files.
