Suppose you have got some useful and sensitive data that you need to share with somebody online, what method can you select to do this? And does this method totally secure your data? Does the information get deleted when it is read by recipients? These are some questions that you need to get answers before you send private notes on the internet.
In this post, we will cover top online service like privnote that allows you to send password and data protected notes online. Using such free web services, you will be able to share some sensitive data online just by adding the password with expiry date and auto shared function. Not all the services are free; some have limitation for the free users. Hence, let us discuss it in complete details.
How Does Data Encryption Work?
Data or text can be encrypted with the encryption algorithm or encryption key. This process results in the ciphertext that can only be viewed in the original form if it’s decrypted with right key.
Kinds of Encryption
The symmetric-key ciphers make use of same secret key to encrypt & decrypt any file or message. Whereas symmetric-key encryption will be faster than the asymmetric encryption, and sender should exchange encryption key with recipient before he will decrypt it.
Since companies need to safely manage and distribute vast quantities of the keys, majority of the data encryption services are adapted and make use of asymmetric algorithm that will exchange secret key just after using the symmetric algorithm for encrypting data.
Alternatively, asymmetric cryptography, at times referred as the public-key cryptography, makes use of two different keys, public and private. Public key can be shared with everybody; however private key should be well-protected. The algorithm’s popularity generally comes from a fact that both private and public keys will encrypt the message to assure authenticity, integrity, confidentiality, and non-repudiability of the data and electronic communications through use of the digital signatures.
Final Words
The encryption algorithm is a method used for transforming data in ciphertext. The algorithm can make use of encryption key to alter data in the predictable way, so although encrypted data can appear random, this will be turned back in plaintext just by using decryption key. It is very important to encrypt messages, data and files that you send if they are sensitive, personal and classified. You do not want the hackers to intercept your message or emails to anyone especially if they are private.
