What is Encryption and Decryption?
Encryption and Decryption is free text encryption software (text encryption freeware) that allows you protect the privacy of your email messages by encrypting them with AES 256-bit key encryption algorithm to provide high protection against unauthorized data access. Once the information has been encrypted, you shouldn't worry your information can be seen by others - you can safely send/receive encrypted messages over the Internet to share private information with your friends, family, co-workers.
How you can use text encryption and decryption software
• Safely send sensitive messages and files over the Internet
Sending sensitive messages, documents and files over the Internet is very dangerous as all emails are transmitted in an unsecured form. So anybody - ISP, your boss, etc. can read your emails. Even if you connect to your server and send your emails via SSL, it only means that your emails can't be seen while transmitting between you and your server. When your email reaches your server it can be seen by your email service provider. Then your server usually sends your email to the recipient in an unsecured way and your email can also be easily seen by anyone.
If you need to send sensitive information over the Internet you should encrypt it first. Encryption and Decryption Pro (text encryption software) allows you easily encrypt and decrypt your text and files. Now you can send emails and files from home or office in a safe way. If you need to send sensitive information via email, simply paste the encrypted text into your email or attach the encrypted file to your email and all the recipient has to do is to decrypt your text or file.
• Safely store sensitive information on your PC
Encryption and Decryption Pro is very useful for storing private documents and files on your PC. Encryption and Decryption Pro works with both - text information and files. Just select what you want to encrypt, and Encryption and Decryption Pro helps you keep documents, private information and files in a confidential way.
• Advanced password generator
Encryption and Decryption Pro uses Universal Random Number Generator (URAND) subroutine for generating really random passwords.
• Password keeper
Encryption and Decryption Pro is easy-to-use password management solution that securely stores all your passwords and associated information
What is Advanced Encryption Standard (AES)?
AES/Rijndael 256-bit key encryption
AES stands for Advanced Encryption Standard. AES is a symmetric key encryption technique which will replace the commonly used Data Encryption Standard (DES).
It was the result of a worldwide call for submissions of encryption algorithms issued by the US Government's National Institute of Standards and Technology (NIST) in 1997 and completed in 2000.
The winning algorithm, Rijndael, was developed by two Belgian cryptologists, Vincent Rijmen and Joan Daemen. AES provides strong encryption and was selected by NIST as a Federal Information Processing Standard in November 2001 (FIPS-197).
The AES algorithm usesthree key sizes: a 128-, 192-, or 256-bit encryption key. Each encryption key size causes the algorithm to behave slightly differently, so the increasing key sizes not only offer a larger number of bits with which you can scramble the data, but also increase the complexity of the cipher algorithm.

How to encrypt text (text encryption)
1. Double-click on Encryption and Decryption Pro desktop icon or tray icon to open Encryption and Decryption Pro main window.
2. Click "Tools" button and select "Encryption" item.
3. Put the radio button next to "Text"
4. Enter or paste the text you want to encrypt in "Text you want to encrypt" area.
• For Windows Vista/XP/2003/2000 max length of text you can encrypt is 524224 characters.
• For Windows 98/ME max length of text you can encrypt is 32704 characters.
5. Click the "Encrypt" button.
6. Enter password for encryption and confirm it. Attention! You have to remember it, because it will be needed for decryption.
"Encrypt with password check confirmation" option is on (by default this option is on after installation, then it remembers its last state)
If "Encrypt with password check confirmation" option is on, your password hash is stored in the encrypted text. Later, when you decrypt the text, the password you enter is hashed and compared with the stored password hash. And, in case, the hash of the password you enter matches the stored password hash, your encrypted text will be decrypted. If you enter wrong password, you'll get en error message "Wrong password".
"Encrypt with password check confirmation" option is off
To mitigate the threat of trivial Brute Force attacks on the encrypted text, you can encrypt your text the way it doesn't store password hash. If you turn off "Encrypt with password check confirmation" option, it prevents program from storing password hash in the encrypted text and makes Brute Force attacks harder.
In this case, if you enter wrong password for decryption, you won't see any error message, your text will be "decrypted" using wrong password and you will see abracadabra instead of the real text.
Don't worry if you decrypted the text with wrong password, your original encrypted text is still stored in the "Encrypted text you want to decrypt" area and you can decrypt it with the correct password.
7. Your text in the encrypted form appears in "Encrypted text" area.
Now you can safely store your text (message) on your PC, send it by email or transfer it in any other ways. If you want to send your message in the encrypted form, just copy it from the "Encrypted text" area and paste it to your email.
To remove information from "Text you want to encrypt" and "Encrypted text" areas, click "Clear fields" button.
How to encrypt file
To encrypt file:
1. Double-click on Encryption and Decryption Pro desktop icon or tray icon to open Encryption and Decryption Pro main window.
2. Click "Tools" button and select "Encryption" item.
3. Put the radio button next to "File"
4. Select the file you want to encrypt in "File you want to encrypt" field. Note: Maximum size of the file you can encrypt is 2 GB
5. In "Save encrypted file to ..." field select where you want to save the encrypted file. You can save encrypted file with the same name or you can change its name.
6. Click the "Encrypt" button.
7. Enter password for encryption and confirm it. Attention! You have to remember it, because it will be needed for decryption.
"Encrypt with password check confirmation" option is on (by default this option is on after installation, then it remembers its last state)
If "Encrypt with password check confirmation" option is on, your password hash is stored in the encrypted file. Later, when you decrypt the file, the password you enter is hashed and compared with the stored password hash. And, in case, the hash of the password you enter matches the stored password hash, your encrypted file will be decrypted. If you enter wrong password, you'll get en error message "Wrong password".
"Encrypt with password check confirmation" option is off
To mitigate the threat of trivial Brute Force attacks on the encrypted file, you can encrypt your file the way it doesn't store password hash. If you turn off "Encrypt with password check confirmation" option, it prevents program from storing password hash in the encrypted file and makes Brute Force attacks harder.
Attention! Be careful while entering password. If you enter wrong password for decryption, you won't see any error message, your file will be "decrypted" using wrong password and it will be overwritten with wrong information and there is no way to recover it except if you have backup. To protect your file information, we recommend you decrypt the file to another file.
8. Now you can safely store your file on your PC, send it by email or transfer it in any other ways.
