Create HMAC Signature | TEXT_HMAC

Syntax

TEXT_HMAC( [value], [secret], [encoding = "hex"], [algorithm = "sha256"] )

Parameters

value
The TEXT to generate the signature for. If it is not a TEXT value, it will be set to an empty TEXT.

secret
The TEXT secret to generate the signature. If it is not a TEXT value, it will be set to an empty TEXT.

encoding optional
The encoding for the output. If not provided, the output will be encoded as hexadecimal. Valid values are:

• hex
• base64

algorithm
The algorithm used to generate the signature. If not provided, the sha256 algorithm will be used. Valid values are:

• sha1
• sha224
• sha256
• sha384
• sha512
• ripemd160

Return Value

A TEXT in the specified ENCODING that is the calculated HMAC signature of VALUE.

Description

Generate an HMAC signature.
