本文實例講述了JS使用插件cryptojs進行加密解密數據。分享給大家供大家參考，具體如下：

Testing websockets

var key = 'BOTWAVEE';

//CBC模式加密

function encryptByDESModeCBC(message) {

var keyHex = CryptoJS.enc.Utf8.parse(key);

var ivHex = CryptoJS.enc.Utf8.parse(key);

encrypted = CryptoJS.DES.encrypt(message, keyHex, {

iv:ivHex,

mode: CryptoJS.mode.CBC,

padding:CryptoJS.pad.Pkcs7

}

);

return encrypted.ciphertext.toString();

}

//CBC模式解密

function decryptByDESModeCBC(ciphertext2) {

var keyHex = CryptoJS.enc.Utf8.parse(key);

var ivHex = CryptoJS.enc.Utf8.parse(key);

// direct decrypt ciphertext

var decrypted = CryptoJS.DES.decrypt({

ciphertext: CryptoJS.enc.Hex.parse(ciphertext2)

}, keyHex, {

iv:ivHex,

mode: CryptoJS.mode.CBC,

padding: CryptoJS.pad.Pkcs7

});

return decrypted.toString(CryptoJS.enc.Utf8);

}

//DES ECB模式加密

function encryptByDESModeEBC(message){

var keyHex = CryptoJS.enc.Utf8.parse(key);

var encrypted = CryptoJS.DES.encrypt(message, keyHex, {

mode: CryptoJS.mode.ECB,

padding: CryptoJS.pad.Pkcs7

});

return encrypted.ciphertext.toString();

}

//DES ECB模式解密

function decryptByDESModeEBC(ciphertext){

var keyHex = CryptoJS.enc.Utf8.parse(key);

var decrypted = CryptoJS.DES.decrypt({

ciphertext: CryptoJS.enc.Hex.parse(ciphertext)

}, keyHex, {

mode: CryptoJS.mode.ECB,

padding: CryptoJS.pad.Pkcs7

});

var result_value = decrypted.toString(CryptoJS.enc.Utf8);

return result_value;

}

function test(){

var source = $("#source").val();

var cc = encryptByDESModeEBC(CryptoJS.enc.Utf8.parse(source));

$("#target").val(cc);

}

function test1(){

var source = $("#sourceS").val();

var dd = decryptByDESModeEBC(source);

$("#jiemi").val(dd);

}
