Question of the day
• How strong is protection in Encryption and Decryption?
Encryption and Decryption uses 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.
