syn.crypt.hash Synchronous

Compute a fixed SHA-384 digest for a byte string. It is a quick way to compare content fingerprints when a script uses the Synapse crypto namespace.

Syntax

Luau

syn.crypt.hash(data: string) -> string

Parameters

Function parameters
Parameter	Type	Description
`data`	`string`	Bytes to hash.

string

The SHA-384 digest as lowercase hexadecimal text.

Use syn.crypt.custom.hash when the other side requires a different supported algorithm. A digest does not keep the input secret.

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

Luau

local fingerprint = syn.crypt.hash("profile-v2")
print(fingerprint)
assert(fingerprint == syn.crypt.hash("profile-v2"))
