crypt.hash

Generates a hash of the provided data.

Syntax

crypt.hash(data: string, algorithm: string, key?: string) -> string

Parameters

Parameter	Type	Description
`data`	`string`	The data to hash
`algorithm`	`string`	Required hash algorithm name
`key`	`string?`	Optional key for `BLAKE2B`; ignored by other algorithms

Returns

Type	Description
`string`	The hexadecimal hash string

Description

crypt.hash generates a cryptographic hash of the input data using the specified algorithm.

Supported Algorithms

Example

local data = "Hello, World!"

local hash = crypt.hash(data, "SHA256")
print("SHA256:", hash)

-- Other algorithms
print("MD5:", crypt.hash(data, "MD5"))
print("SHA1:", crypt.hash(data, "SHA1"))
print("SHA512:", crypt.hash(data, "SHA512"))
