LibSodium.Bindings.ShortHashing

The short-input hashing functions have a variety of use-cases, such as:

Note however that the output of cryptoShortHash is only 64 bit. Therefore, it should not be considered resistant to collisions.

The cryptoShortHashX24 function has a 128-bit output which is more resistant to collisions.

Functions

4 declarations

valuecryptoShortHashKeyGen

Create a secret key of size cryptoShortHashKeyBytes.

It is implemented by libsodium with randombytesBuf

valuecryptoShortHash

:: Ptr CUChar
Buffer that will hold the fingerprint, of size cryptoShortHashBytes.
-> Ptr CUChar
Buffer that holds the input message.
-> CULLong
Length of the input message.
-> Ptr CUChar
Buffer that holds the secret key, of size cryptoShortHashKeyBytes.
-> IO CInt
The function returns -1 if the hashing fails and 0 on success.

Hash an input message with a secret key. The secret key is of size cryptoShortHashKeyBytes and can be generated with cryptoShortHashKeyGen.

valuecryptoShortHashX24KeyGen

It is implemented with randombytesBuf

valuecryptoShortHashX24

:: Ptr CUChar
Buffer that will hold the fingerprint, of size cryptoShortHashSipHashX24Bytes.
-> Ptr CUChar
Buffer that holds the input message.
-> CULLong
Length of the input message.
-> Ptr CUChar
Buffer that holds the secret key, of size cryptoShortHashSipHashX24KeyBytes.
-> IO CInt
The function returns -1 if the hashing fails and 0 on success.
