International Data Encryption Algorithm (IDEA): The International Data Encryption Algorithm (IDEA) is a symmetric-key block cipher known for its strength and efficiency in encrypting electronic data. IDEA utilizes 64-bit blocks and a complex series of operations in multiple rounds to provide a high level of security. It’s widely respected for its design and has been used in various encryption protocols, notably in some versions of the Pretty Good Privacy (PGP) protocol for securing emails.
