Encryption:
The process of converting plaintext into ciphertext using an algorithm and a key to secure information during transmission or storage.
Plaintext:
The original, human-readable data or message before encryption is applied
Algorithm:
A set of well-defined steps or rules followed to perform encryption and decryption.
Ciphertext:
The encrypted, unreadable output produced by applying an encryption algorithm to plaintext.
Key: .
A piece of information used by an encryption algorithm to control the transformation of plaintext into ciphertext and vice versa
Symmetric Encryption:
A type of encryption where the same key is used for both encryption and decryption.
Private Key:
In asymmetric encryption, the key that is kept secret and used for decrypting messages.
Asymmetric Encryption:
A type of encryption that involves a pair of keys (public and private) where data encrypted with one key can only be decrypted by the other key.
Public Key:
In asymmetric encryption, the key that is shared openly and used for encrypting messages.
AES (Advanced Encryption Standard):
A symmetric encryption algorithm widely adopted for securing sensitive information.
RSA:
A widely used asymmetric encryption algorithm named after its inventors: Ron Rivest, Adi Shamir, and Leonard Adleman.
Hash Function:
A one-way function that transforms data into a fixed-size string of characters, commonly used for integrity verification.
Digital Signature:
A cryptographic technique that verifies the origin and integrity of a digital message or document.
SSL/TLS:
Protocols that provide secure communication over a computer network, commonly used for securing web traffic.
Key Exchange:
The process by which cryptographic keys are shared between two parties to enable secure communication
