怎么使用js sha512加密

使用js sha512加密的方法：

1、首先去git上下载sha512.js引御李入需要调用的页面上。

2、调用方法，在head和</head>之间的script标签写入以下js代码：

function calcHash() {

try {

var hashInput = document.getElementById("hashInputText");

var hashInputType = document.getElementById("hashInputType");

var hashVariant = document.getElementById("hashVariant");

var hashRounds = document.getElementById("hashRounds");

var hashOutputType = document.getElementById("hashOutputType");

var hashOutput = document.getElementById("hashOutputText"乎轿);

var hashObj = new jsSHA(

hashVariant.options[hashVariant.selectedIndex].value,

hashInputType.options[hashInputType.selectedIndex].value,

{numRounds: parseInt(hashRounds.value, 10)}

);

hashObj.update(hashInput.value);

hashOutput.value = hashObj.getHash(hashOutputType.options[hashOutputType.selectedIndex].value);

} catch(e) {

hashOutput.value = e.message

}

}

function calcHMAC() {

try {

var hmacText = document.getElementById("hmacInputText");

var hmacTextType = document.getElementById("hmacTextType");

var hmacKeyInput = document.getElementById("hmacInputKey");

var hmacKeyInputType = document.getElementById("hmacKeyType");

var hmacVariant = document.getElementById("hmacVariant");

var hmacOutputType = document.getElementById("hmacOutputType");

var hmacOutput = document.getElementById("hmacOutputText");

var hmacObj = new jsSHA(

hmacVariant.options[hmacVariant.selectedIndex].value,

hmacTextType.options[hmacTextType.selectedIndex].value

);

hmacObj.setHMACKey(

hmacKeyInput.value,

hmacKeyInputType.options[hmacKeyInputType.selectedIndex].value

);

hmacObj.update(hmacText.value);

hmacOutput.value = hmacObj.getHMAC(hmacOutputType.options[hmacOutputType.selectedIndex].value);

} catch(e) {

hmacOutput.value = e.message

}

}

其岁拆肆中jsSHA是sha512.js内已经实现的方法。
