Electronic Code Book (ECB) mode of operation uses the most basic approach where the plaintext is divided into blocks, and each block is then encrypted separately. However, ECB has several weaknesses, particularly in terms of security and confidentiality, as duplicate plaintext blocks result in duplicate ciphertext blocks. Therefore, ECB is not recommended for sensitive or critical applications, but it can be useful in some specific scenarios where security is not a primary concern, such as encryption of non-sensitive data or low-level cryptographic protocols.
