OIC - Generate SHA-256 Checksum Using JavaScript in OIC

Oracle Integration Cloud (OIC) provides a built-in checksum function to generate a SHA-256 hash without using any external library. This is useful when creating request signatures or validating message integrity.

JavaScript Action (SHA256Generator.js)

function checksum_sha256(inputStr) {
    var sha256_result = oic.checksum.sha256(inputStr, "sha-256");
    return sha256_result;
}

Use Cases

Generate SHA-256 checksum for REST requests.

Create secure hash values for authentication.

Verify message integrity before sending data.

This reusable JavaScript action can be called from any OIC integration whenever a SHA-256 checksum is required.
