 What is Encryption And Decryption Pro?
Encryption and Decryption Pro is strong text and file encryption software for personal and professional security. It allows you to protect the privacy of your email messages, documents and sensitive files by encrypting them with AES 256-bit key encryption algorithm to provide high protection against unauthorized data access.

What is the difference between EncryptionAndDecryption Pro and EncryptionAndDecryption?
Encryption and Decryption is text encryption freeware.
Encryption and Decryption Professional Edition is more powerful. It is text and files encryption software.

I forgot my password. How can I get the data back?
Our software has no backdoors. If you forgot or lost your password, there is no way to recover the encrypted information.
[top]
How long my password should be to ensure better protection?
Each character you add to your password length increases its security. Your passwords should be 12 or more characters in length. The more characters your password contains, the more difficult it can be to guess.
Password length is even more important than using different additional characters. E.g. if you use standard English alphabet (A-Z, a-z) and digits (0-9) - total 62 characters, increasing password length from 6 to 8 characters causes the number of possible passwords will be increased in 3844 times. While 18 additional special characters that can be used for creating passwords (total 80 characters) if password length is 6 characters, will increase the number of possible passwords only in about 4.6 times.

Is the password stored in the encrypted file or text?
No, password is stored neither in the encrypted file nor in the encrypted text.
If "Encrypt with password check confirmation" option is on while encrypting:
Your password hash (not password) is stored in the encrypted text/file. The program will
compare this hash with the hash of the password you enter for decryption. If they are identical, the program will decrypt information.
Hashing is a one way action only; it is impossible to derive the password from the hash. The hashing process is simply a way of checking
that the correct password has been input.
If "Encrypt with password check confirmation" option is off while encrypting:
To mitigate the threat of trivial Brute Force attacks on the encrypted information, you can encrypt it 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 or file and makes Brute Force attacks harder.
In this case, you enter wrong password for decryption, you won't see any error message, text or file will be "decrypted" using wrong password and you will see abracadabra instead of the real information.

How to encrypt text
1. Enter the information you want to encrypt in "Text you want to encrypt" area and press "Encrypt" button.
2. Enter password for encryption and confirm it.
3. Select if you want to use "Encrypt with password check confirmation" option or not and click "OK". For more information about "Encrypt with password check confirmation" option click here
4. For more security you can encrypt your text multiple times. Set the necessary number of passes for multiple encryption and click 'OK'.
5. Your text in the encrypted form appears in "Encrypted text" area.

How to decrypt text
1. Open Encryption and Decryption Pro main window.
2. Click "Tools" button and select "Decryption" item.
3. Put the radio button next to "Text"
4. Paste the text you want to decrypt in "Encrypted text you want to decrypt" area.
5. Click the "Decrypt" button.
6. Enter password for decryption and confirm it. Note: it is the same password that was used for text encryption
7. Decrypted text appears in the "Decrypted text" window.

What is the maximum length of text I can encrypt?
If you use Encryption and Decryption Professional Edition:
- 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.
If you use Encryption and Decryption (free version):
Max length of text you can encrypt is 255 characters
[top]
What is "Encrypt with password check confirmation" option?
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.

How to encrypt files
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.
8. Select if you want to use "Encrypt with password check confirmation" option or not and click "OK". For more information about "Encrypt with password check confirmation" option click here
9. For more security you can encrypt file multiple times. Set the necessary number of passes for multiple encryption and click 'OK'.

How to decrypt files
1. Open Encryption and Decryption Pro main window.
2. Click "Tools" button and select "Decryption".
3. Put the radio button next to "File"
4. Select the file you want to decrypt in "File you want to decrypt" field.
5. In "Save decrypted file to ..." field select where you want to save the decrypted file. You can save decrypted file with the same name or you can change its name.
6. Click the "Decrypt" button.
7. Enter password for decryption and confirm it. Note: it is the same password that was used for file encryption
[top]
What is the maximum size of file I can encrypt?
Maximum size of the file you can encrypt is 2 GB.
[top]
What kinds of files can be encrypted?
Using Encryption and Decryption you can encrypt any kind of file.

How strong is protection in Encryption and Decryption?
The program 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.
