The keystream is generated using a pseudorandom number generator (PRNG) or a stream cipher algorithm. The keystream is then combined with the plaintext using an XOR operation to generate the ciphertext. Since the keystream is generated continuously, the length of the plaintext and ciphertext is usually the same. Stream ciphers are generally faster than block ciphers and can be used for real-time encryption of data.<\/p><p>On the other hand, a block cipher divides the plaintext into fixed-size blocks, typically 64 or 128 bits in length, and encrypts each block separately. The most commonly used mode of operation is the Electronic Codebook (ECB) mode, where each block is encrypted using the same key. Other modes, such as Cipher Block Chaining (CBC), Counter (CTR), and Galois\/Counter Mode (GCM), provide better security by adding additional inputs, such as an initialization vector (IV), to each block. Block ciphers are slower than stream ciphers but provide better security and can be used to encrypt large amounts of data.<\/p><p>In summary, stream ciphers encrypt data bit-by-bit or byte-by-byte using a continuous keystream, while block ciphers divide the plaintext into fixed-size blocks and encrypt each block separately.<\/p><p><strong>\u00a0<\/strong><\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-accordion-item\">\n\t\t\t\t\t<div id=\"elementor-tab-title-20915\" class=\"elementor-tab-title\" data-tab=\"15\" role=\"button\" aria-controls=\"elementor-tab-content-20915\" aria-expanded=\"false\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon elementor-accordion-icon-left\" aria-hidden=\"true\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-closed\"><svg class=\"e-font-icon-svg e-fas-plus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H272V64c0-17.67-14.33-32-32-32h-32c-17.67 0-32 14.33-32 32v144H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h144v144c0 17.67 14.33 32 32 32h32c17.67 0 32-14.33 32-32V304h144c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t<span class=\"elementor-accordion-icon-opened\"><svg class=\"e-font-icon-svg e-fas-minus\" viewBox=\"0 0 448 512\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M416 208H32c-17.67 0-32 14.33-32 32v32c0 17.67 14.33 32 32 32h384c17.67 0 32-14.33 32-32v-32c0-17.67-14.33-32-32-32z\"><\/path><\/svg><\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-accordion-title\" tabindex=\"0\">15.
