WebMar 7, 2024 · Encryption is a process which transforms the original information into an unrecognizable form. Decryption is a process of converting encoded/encrypted data in a form that is readable and understood by a human or a computer. Encryption method helps you to protect your confidential data such as passwords and login id. WebCryptography ensures confidentiality by encrypting sent messages using an algorithm with a key only known to the sender and recipient. A common example of this is the messaging …

WebExamples: AES DES Caesar Cipher Public Key Cryptography, or asymmetric cryptography, uses two keys to encrypt data. One is used for encryption, while the other key can decrypts the message. Unlike symmetric cryptography, if one key is used to encrypt, that same key cannot decrypt the message, rather the other key shall be used. WebApr 12, 2024 · Note that steganography and cryptography are not mutually exclusive. For example, steganography could hide a message inside another file using encryption for extra security. The recipient could then extract the encrypted message and decrypt it using a given key. Examples of Steganography. Steganography has been in use for centuries. eastchester ny school board
