In cryptography, a key derivation function (or KDF) derives one or more secret keys from a secret value such as a master key or other known information such as a password or passphrase using a pseudo-random function. Keyed cryptographic hash functions are popular examples of pseudo-random functions ...
Microsoft has created an implementation of PBKDF1 in the PasswordDeriveBytes class. It can however generate more bytes than PBKDF1, which is limited to the number ...
Imagine I have four files I want to encrypt. I have master key, and from that master key I derive four keys, one for each file: ...
I have two network endpoints that need to use the same derived key. Can the server send the salt to the client 'in the clear'?
