This program goals is to keep safely passowrds that the user wants to store in it. for storing passwords by site/address, searches passwords by address and saves passwords to file with simple “encryption”.

1. Storing passwords.
2. Searching for passowrd by typing address of a site.
3. Savinf passwords to file.
4. Printing a report of sites and passwords.

• The encryption is based on master key that is asked from the user.
• The master key is be stored anywhere.
• If the user forgets the master key the passwords can’t be recovered.
• Passwords are decrypted only when displayed and plaintext password must be wiped from memory after display.
• Program encrypts the passwords by performing xor-operation between master key and the password.
• Encryption is performed by xoring each character in the password with a character from the master key.
• Master key is repeated consecutively over the password.
• The encryption may produce zero as a result of encryption so you need to store the length of the password to be able decrypt the password later.
• Running the “encryption” twice using the same master key should returns password to its original state.
