Why you should use encryption
Nowadays when more and more sensitive information is stored on computers and transmitted over the Internet, we need to ensure information security and safety.
One of the most common uses of encryption is encrypting emails. Sending sensitive messages, documents and files over the Internet is like sending a postcard as all emails are transmitted in an unsecured form. It doesn't depend on if you send emails via public and private networks. Your message is totally open to interception by anyone along the way - so anybody - your 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.
Private network, where email goes directly to a mail server and resides there until it is retrieved, also doesn't provide necessary security level, as you email can be seen e.g. by network administrator, your boss, etc.
Of course, you may believe that your personal email does not contain any private information, but everyone has got something to keep in secret from his family, neighbors or colleagues. It could be financial, sexual, social, political, or professional secrets. There is really only one sure way to protect your email privacy - using encryption.
• Want to send secure emails to your friends or partners so nobody can read them?
• Are you afraid that someone else can see sensitive data stored on your computer?
• Want to protect your files with passwords so only you can access them?

How strong is protection in Encryption and Decryption?
Both Encryption and Decryption software and freeware use AES 256-bit key encryption algorithm. AES provides strong encryption and was selected by NIST as a Federal Information Processing Standard in November 2001 (FIPS-197). Currently, there are no computers that could break the encryption key in a reasonable amount of time (it will take millions of years). A password, or more precisely its hash (SHA 256), is used to protect the encryption key. Neither the password nor its hash is stored anywhere. If the password is not correct, it will be impossible to get the encryption key and consequently to decrypt information.
How to use Encryption and Decryption for sending secure emails
1. At first you should provide the recipient with the password for decryption. In order to maintain security, it is important, that the password is distribute to the recipient without letting it fall into the wrong hands.
2. Enter the information you want to encrypt in "Text you want to encrypt" area and press "Encrypt" button.
3. Enter password for encryption and confirm it.
4. Select if you want to use "Encrypt with password check confirmation" option and click "OK".
If "Encrypt with password check confirmation" option is on
Your password hash is stored in the encrypted text. Later, when the recipient decrypts the text, the password he/she enters is hashed and compared with the stored password hash. And, in case, the hash of the password the recipient enters matches the stored password hash, encrypted message will be successfully decrypted. If the recipient enters wrong password, he/she will get an error message "Wrong password".
If "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 message the way it doesn't store password hash. If you turn off "Encrypt with password check confirmation" option, it prevents the program from storing password hash in the encrypted text and makes Brute Force attacks harder.
In this case, if the recipient enters wrong password for decryption, he/she won't see any error message, text will be "decrypted" using wrong password and the recipient will see abracadabra instead of the real text.
But don't worry - your original encrypted text is still stored in the "Encrypted text you want to decrypt" area.
5. For more security you can encrypt your text multiple times. Set the necessary number of passes for multiple encryption and click 'OK'.
6. Your text in the encrypted form appears in "Encrypted text" area.
7. Now you can send it by email - just copy it from the "Encrypted text" area and paste it into your email. To copy the encrypted text, right-click on the text and select 'Select all', then right-click again and select 'Copy'.
8. After the recipient receives the email with your encrypted message, he/she should:
- paste the encrypted text in "Encrypted text you want to decrypt" area;
- click the "Decrypt" button;
- enter the password for decryption (you provided him/her before) and confirm it. Note: it is the same password that was used for text encryption
Note: If "Encrypt with password check confirmation" option was on while encryption and the recipient enters wrong password, he/she will get en error message "Wrong password".
If "Encrypt with password check confirmation" option was off while encryption and the recipient enters wrong password for decryption, he/she won't see any error message, the text will be "decrypted" using wrong password and the recipient will see abracadabra instead of the real text. Don't worry if the text was decrypted with wrong password, the original encrypted text is still stored in the "Encrypted text you want to decrypt" area and the recipient can decrypt it with the correct password.
9. If the recipient wants to send you an encrypted message, he/she shoud do the same. Note: the recipient can use the same password for text encryption or use another password. If he/she uses another password for encryption, he/she should provide you with it so you can decrypt his/her message.
How to use Encryption and Decryption to encrypt files
'File encryption' option is available in Encryption and Decryption Pro only.
To encrypt file:
1. Double-click on Encryption and Decryption Pro desktop icon.
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. 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 'Encrypt' button.
7. Enter password for encryption and confirm it.
Note:
- 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".
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.
8. Now you can safely store your file on your PC, send it by email or transfer it in any other ways.
To remove information from 'File you want to encrypt' and 'Save encrypted file to' areas, click 'Clear fields' button.
What is "Multiple encryption" option?
"Multiple encryption" option is available in Encryption and Decryption Pro only. For more security and to prevent Brute Force attack you can encrypt the same text or file multiple times -just set number of passes for multiple encryption.
Encryption And Decryption - encryption and decryption has never been easier!
