HMACBinary

HMACBinary(secret: Binary, content: Binary, algorithm: String = "HmacSHA1"): Binary

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

See also, HMACWith.

Parameters

Name Description

secret

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

content

The binary input 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.
