No encryption standard can be robust forever. Different Types of EncryptionĪs mentioned, cryptography isn’t a new idea. Because of it, users don’t have to rely on the same key to lock and unlock information online. Public key cryptography (another term for asymmetric encryption) is the foundation for all forms of secure messaging on the open internet. So, having knowledge of one won’t be enough to guess the other. In other words, a private key can’t decrypt a message encrypted by a public key that it doesn’t match.Īlthough intertwined, public and private keys are not derived from each other. Created in pairs, they’re mathematically linked to one another. Where do these two types of encryption keys come from? Asymmetric encryption algorithms dictate their generation. It must be kept secret from everyone else. The private is the one that can decipher the encrypted data you received. The public key is the one that you can share with other people and that can encrypt text. It’s like a lockable mailbox with a mail slip that has its own lock. It’s like a lockable mailbox without a mail slip.Īsymmetric is when two keys (a public one and a private one) are used to transmit unreadable information on the internet.
When the sender and the recipient use just a single key to exchange a message securely – that’s symmetric. There are two types of cryptography : symmetric and asymmetric. Think of encryption and decryption this way:Ī method of locking (scrambling) and unlocking (bringing it back to original) data with unique keys ( passwords ), which are unfathomably long numbers.

In fact, it’s one of the underlying technologies that powers cryptocurrencies (hence the name), virtual private networks (VPNs), password managers, etc. Now, it has evolved into sophisticated tech. The earliest record of its usage dates back to ancient Egypt. Safeguarding privacy is a top priority for discerning internet users.Ĭryptography is as old as pharaohs. The act of restoring the encrypted data back to its original form is called decryption. The act of changing the format of data from comprehensible to unintelligible is called encryption. The readable text is called plaintext, whereas the scrambled version is ciphertext. We’ll tell you, but you first need to know what cryptography is.Ĭryptography is any process of turning understandable data into gibberish. Also, there are different types of encryption. What you might not know is that there are the so-called keys and they have different lengths. You know it protects your data from hackers. This word is constantly thrown around in reviews, specifications, and basically all things internet-related.
