能否判断电子签名的内容js

const crypto = require('crypto');

function generateHash(message) {
    return crypto.createHash('sha256').update(message).digest('hex');
}

            saltLength: crypto.constants.RSA_PSS_SALTLEN_DIGEST
        },
        Buffer.from(signature),
        Buffer.from(messageHash)
    );
}

async function checkElectronicSignature(publicKey, signature, originalMessage) {
    const messageHash = generateHash(originalMessage);
    const isValid = verifySignature(publicKey, signature, messageHash);
    return isValid;
