1. 为什么抉择应用JavaScript来复现算法
JS实现的算法，能够很不便地被任何语言调用
2. CryptoJS中音讯摘要算法的应用
CryptoJS.MD5(message);CryptoJS.HmacMD5(message, key);CryptoJS.SHA1(message);CryptoJS.HmacSHA1(message, key);CryptoJS.SHA256(message);CryptoJS.HmacSHA256(message, key);CryptoJS.SHA512(message);CryptoJS.HmacSHA512(message, key);CryptoJS.SHA3('xiaojianbang', {outputLength: 256})3. 音讯摘要算法的其余调用模式
SHA256var hasher = CryptoJS.algo.SHA256.create();hasher.reset();hasher.update('message');hasher.update(wordArray);var hash = hasher.finalize();var hash = hasher.finalize('message');var hash = hasher.finalize(wordArray);HmacSHA256var hmacHasher = CryptoJS.algo.HMAC.create(CryptoJS.algo.SHA256, key);hmacHasher.reset();hmacHasher.update('message');hmacHasher.update(wordArray);var hmac = hmacHasher.finalize();var hmac = hmacHasher.finalize('message');var hmac = hmacHasher.finalize(wordArray);4. CryptoJS(字符串解析)
