Detailed explanation-1: -An encryption key is typically a random string of bits generated specifically to scramble and unscramble data. Encryption keys are created with algorithms designed to ensure that each key is unique and unpredictable. The longer the key constructed this way, the harder it is to break the encryption code.
Detailed explanation-2: -Encryption is a way of scrambling data so that only authorized parties can understand the information. In technical terms, it is the process of converting human-readable plaintext to incomprehensible text, also known as ciphertext.
Detailed explanation-3: -Encryption uses complex mathematical algorithms and digital keys to encrypt data. An encryption algorithm (cipher) and an encryption key encode data into ciphertext. Once the ciphertext is transmitted to the recipient, the same or different key (cipher) is used to decode the ciphertext back into the original value.
Detailed explanation-4: -Encryption keys are strings of information (bits) that are used by cryptographic algorithms to encode (encrypt) and decode (decrypt) data. Encrypted data is unreadable without proper decoding, thus making it highly secure and difficult for hackers to compromise.
Detailed explanation-5: -How does encryption work? Encryption takes plain text, like a text message or email, and scrambles it into an unreadable format-called “cipher text.” This helps protect the confidentiality of digital data either stored on computer systems or transmitted through a network like the Internet.
