Signer Object Members for SuiteScript in NetSuite

The Signer object is vital for secure communications in SuiteScript, allowing developers to sign strings securely. This feature supports server scripts and is particularly useful in situations requiring digital signatures.

What is the Signer Object?

The Signer object encapsulates a created signature for plain strings and is returned by the certificate.createSigner(options) method. It is a key component of the N/crypto/certificate module.

Signer Object Members

The Signer object includes two main methods that are used for signing operations:

Using the Signer Object

Here's how you can utilize the Signer object in your SuiteScript:

1// Example usage of the Signer object
2var mySigner = certificate.createSigner({
3    certId: 'custcertificate1',
4    algorithm: certificate.HashAlg.SHA512
5});
6 
7mySigner.update("test"); // Update the string to be signed
8var result = mySigner.sign({
9    outputEncoding: encode.Encoding.BASE_64_URL_SAFE,
10    useRawFormatForECDSA: true
11});

Method Details

• Signer.sign(options): This method is crucial for signing a string and can format the result in various ways, including Base64 encoding.
• Signer.update(options): Use this method to modify the input string that will be signed. This method supports plain and encoded strings.
