WebTriple DES (or TDES or TDEA or 3DES) is a symmetric block cipher standardized by NIST in SP 800-67 Rev1 , though they will deprecate it soon. TDES has a fixed data block size of 8 bytes. It consists of the cascade of 3 Single DES ciphers (EDE: Encryption - Decryption - Encryption), where each stage uses an independent DES sub-key.
WebThe Caesar Cipher is one of the simplest symmetric encryption techniques, and of course, one of the easiest to crack. Since then, cryptologists have invented many more symmetric encryption techniques, including the ones used today to encrypt data like passwords. Vigenère Cipher French cryptologists invented the Vigenère Cipher in the mid 1500s.

WebApr 10, 2024 · When plain text is encrypted it becomes unreadable and is known as ciphertext. In a Substitution cipher, any character of plain text from the given fixed set of characters is substituted by some other character from the same set depending on a key. For example with a shift of 1, A would be replaced by B, B would become C, and so on. WebNov 18, 2024 · DES stands for Data Encryption Standard. There are certain machines that can be used to crack the DES algorithm. The DES algorithm uses a key of 56-bit size. Using this key, the DES takes a block of 64-bit plain text as input and generates a block of 64-bit cipher text. The DES process has several steps involved in it, where each step is called ...
WebDec 6, 2024 · The simplest substitution cipher is one that replaces each alphabet in a text by the alphabet k positions away (in the modulo 26 sense). For k = 3, the substitutions are D for A, E for B, A for X, B for Y, etc. Such a scheme is referred to as a Caesar cipher. A sample plaintext and the corresponding ciphertext for k= 3 is
