WebApr 11, 2024 · Cryptographic security is a key component of data security, and salting and key stretching are two important methods used to protect data from malicious actors. Salting and key stretching are both used to increase the complexity of cryptographic keys, making them more difficult to guess or crack. Web“Hello”, for example, will always equal to the same combination of letters and numbers, and therefore can be guessed through brute force. One way of protecting against this is by adding a salt or using salted passwords. Salting is the act of adding a series of random …
