syn.crypt.custom.hash Synchronous

syn.crypto.custom.hash

Compute a digest using one of the Synapse compatibility library’s supported algorithms. Use it to select a digest algorithm while keeping the compatibility calling convention. The algorithm is the first argument here; crypt.hash takes the data first.

Syntax

Luau

syn.crypt.custom.hash(algorithm: string, data: string) -> string

Parameters

Function parameters
Parameter	Type	Description
`algorithm`	`string`	MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-384, or SHA3-512. Case and common separator variants are normalized.
`data`	`string`	Bytes to hash.

Returns

string

The digest as lowercase hexadecimal text.

Availability

This function requires the Synapse environment setting, which is off by default.

Example

Luau

-- Enable the Synapse environment setting first.
local digest = syn.crypt.custom.hash("SHA256", "example contents")
print(digest)
print(#digest) -- 64 hexadecimal characters
