Encryption has been used for centuries to keep information away from potential hackers and prying eyes. It is also essential for safely transmitting any sensitive data you may have. If a message contains private information, it needs to be encrypted before being sent so that the contents of the message cannot be read by unauthorized parties. The only solution for encrypting it is to use a password. This password will be used as a second factor of authentication and the recipients’ computers only need to store it for one time. But, how about sending encrypted private note messages without the need for any extra authentication? Well, this can be done using ciphers, but the main problem with them is that they generate random strings which can be easily guessed by any computer system running a brute force attack.
Self-Destructing Password
Another solution is to use self-destructing passwords. The theory behind this concept is that the password will be used as a second factor of authentication and it will be stored in a text file on the recipient’s computer. This file can be protected and only accessible for one time. If the password file is not provided, the next time it’s required, an input will automatically erase all files on its PC. As this does not require any additional authentication, it is much safer than the previous method.
Free Online Tools
There are many free online tools that provide this functionality. One of them being the pirvnota Email Encryptor which will allow you to encrypt and decrypt messages with a very simple interface that includes some pre-configured settings. Another tool is the Off-the-Record Messaging which allows users to easily send encrypted messages without the need for an extra authentication factor (such as a password).
Encryption with Email Clients
If you want to use a more advanced tool that allows you to encrypt and decrypt messages, you can use the pirvnota add-on for your email client. It will automatically generate additional passwords for every recipient of an email. When an encrypted message is sent, the password used to decrypt it is only stored in the PC of the recipient, so it is much harder for hackers to access it.
Nevertheless, these tools do not encrypt an entire email and they have a limited number of recipients who can decrypt it. Also, these passwords cannot be used only once, which will make the encryption process less secure. So you should use them to send sensitive information that does not require extra authentication.
The beauty of self-destructing messages is that no one can access them. This is a great way to protect yourself from hackers who want to steal your private information.
