What is a cryptographically secure random number …

WebIf you generate a truly random series of numbers to use as the encryption key, then you need to send the entire series to you recipient. Also, you cannot simply send it as is or the eavesdropper with see both the encrypted data and the encryption key and be able to decrypt the data. This is why methods like public key encryption are used. WebIdeally, the output of any encryption algorithm, will appear very nearly to be random. This also requires that the key utilized in that algorithm also be nearly random. This brings us to pseudo random number generators. They are called ‘pseudo’ because the output is not truly completely random. dalnice info
