WebVariables are technically defined as reserve memory location to store values. Thus, when you create a variable, the space is reserved for the variable in the memory. The operand to the left of the operator is the name of the variable. The operand to the right of the operator is the value stored in the variable. A cryptographic hash function (CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with fixed size of bits) that has special properties desirable for a cryptographic application: • the probability of a particular -bit output result (hash value) for a random input string ("message") is (like for any good hash), so the hash value can be used a…

WebRC5 was developed by Ron Rivest. It is a block encryption algorithm based on the symmetric key. The main feature of this is, it is quite fast as it uses only primitive computer operations. It allows a variable number of rounds and variable bit size key to add flexibility. Another advantage of using RC5 is that it requires less memory for execution. Webprivate key (secret key): In cryptography , a private key (secret key) is a variable that is used with an algorithm to encrypt and decrypt code. Quality encryption always follows a fundamental rule: the algorithm doesn't need to be kept secret, but the key does. Private keys play important roles in both symmetric and asymmetric cryptography. dynal magnetic beads
