This function returns a hash of the specified string in the specified algorithm.

Syntax

string hash ( string algorithm, string dataToHash, [ table options ] )

Required Arguments

  • algorithm: A string which must be one of these: "md5", "sha1", "sha224", "sha256", "sha384", "sha512", "hmac"
  • dataToHash: A string of the data to hash.
  • options: A table with options and other necessary data for the algorithm, as detailed below.

Options for each algorithm

  • hmac (HMAC)
    • key: a key to encode the input with.
    • algorithm: a string which must be one of these: "md5", "sha1", "sha224", "sha256", "sha384", "sha512".

Returns

Returns the hash of the data, false if an invalid argument was used.

Example

local myString = "myDatatoHash"
print(hash("md5", myString)) -- This will hash myString with the md5 Algorithm (it's equal to md5()) -> output: 0EF1E2203BD78182911B77EB6B9CC3DE

-- A another Example
local myNewString = "myNewDatatoHash"
print(hash("sha512", myNewString)) -- This will hash myNewString with the sha512 Algorithm -> output: 64A5678DC83EDCD8991E8CF0D69764663C0F933870BB89465F77B6C23D2A2B2400305A36D77404EE647D0D7B9D56CF7937B235BBD3885D08DCC62C81FB6D8429
