WebKey generation is the process of generating keys for cryptography. The key is used to encrypt and decrypt data whatever the data is being encrypted or decrypted. Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA ). Symmetric-key algorithms use a single shared key; … WebCryptographic algorithms require keys. A Random Number Generator (RNG), also called a Random Bit Generator (RBG), is needed in the key generation process to create a random (strong) key as well as for other cryptographic purposes such as …
