HMACBinary

HMACBinary(Binary, Binary, String): Binary

Computes an HMAC hash (with a secret cryptographic key) on input content.

Parameters

Name Description

Name	Description
`secret`	The secret cryptographic key (a `Binary`) used when encrypting the `content`).
`content`	The input content, a `Binary` value.
`algorithm`	The hashing algorithm. `HmacSHA1` is the default. Valid values depend on the JDK version you are using. For JDK 8 and JDK 11, `HmacMD5`, `HmacSHA1`, `HmacSHA224`, `HmacSHA256`, `HmacSHA384`, and `HmacSHA512` are valid algorithms. For JDK 11, `HmacSHA512/224` and `HmacSHA512/256` are also valid.

secret

The secret cryptographic key (a Binary) used when encrypting the content).

content

The input content, a Binary value.

algorithm

The hashing algorithm. HmacSHA1 is the default. Valid values depend on the JDK version you are using. For JDK 8 and JDK 11, HmacMD5, HmacSHA1, HmacSHA224, HmacSHA256, HmacSHA384, and HmacSHA512 are valid algorithms. For JDK 11, HmacSHA512/224 and HmacSHA512/256 are also valid.

Example

This example uses HMAC with a secret value to encrypt the input content.
