In cryptography, plaintext is usually ordinary readable text before it is encrypted into ciphertext, or readable text after it is decrypted. Data input to or output fromencryptionalgorithms is not always plaintext. For example, when data issuperencrypted, or encrypted more than once using differen...
Cryptography is the process of hiding or coding information so only the intended recipient can read a message. Discover how cryptography works and the potential risks it poses.
In cryptography, a plaintext message is converted to ciphertext using a combination of numerical computations that appear incomprehensible to the untrained eye. Techniques like mathematical concepts and algorithms are used to make the transferred data difficult for others to decode. In other words, the...
In asymmetric encryption, a public key is used to encrypt a message and a private key is used to decrypt it. The exact technique used to scramble plaintext into ciphertext defines how cryptography works. Symmetric encryption, asymmetric encryption, blockchain, and digital signatures are some promi...
The specific knowledge needed to revert a ciphertext into plaintext, known as the key, must be kept secret to ensure a message's security. To crack a cipher without its key takes great knowledge and skill. In the digital era, the goal of cryptography remains the same: to prevent informati...
An encryption algorithm is the method used to transform data into ciphertext. An algorithm will use the encryption key in order to alter the data in a predictable way, so that even though the encrypted data will appear random, it can be turned back into plaintext by using the decryption ke...
Cryptography provides for secure communication in the presence of malicious third-parties—known as adversaries. Encryption uses an algorithm and a key to transform an input (i.e., plaintext) into an encrypted output (i.e., ciphertext). A given algorithm will always transform the same plaintex...
This method is also called secret-key or private-key cryptography because only a single key is used during the process. There are two main types of symmetric key cryptography: Stream Cipher - A streaming algorithm encrypts plaintext bit-by-bit, a single bit at a time. The same plaintext ...
The original format is called plaintext while the unreadable format is referred to as ciphertext. Parties use an encryption scheme called an algorithm and keys for encryption and decryption of messages in a private conversation. The decryption algorithm is also known as a cipher. Why is Decryption...
Cryptography is the practice of developing and using coded algorithms to protect and obscure transmitted information.
