libsodium-net offers a couple of hash functions for the following purposes:

Generic hashing

Common use cases:

  • File integrity checking
  • Creating unique identifiers to index arbitrary long data

Note: If you are looking for a faster and more secure alternative than MD5 or SHA1 you want this!

  • Probabilistic data structures such as Bloom filters
  • Integrity checking in interactive protocols

Password hashing

Common use cases:

  • Deriving a key from a password and a salt
  • Protecting an on-disk secret key with a password,
  • Password storage, or rather: storing what it takes to verify a password without having to store the actual password.
